What is it? .
Hyaluronic Acid (HA) is classified as a glycosaminoglycan capable of holding up to 1,000 times its weight in water. It is like an enormous sponge. The skin accounts for about half of all the HA found in the entire body. In fact, one reason that hormone replacement treatments sometimes cause the skin to look more youthful and less sun-damaged is because they increase the skin’s HA concentration.
How does it work?
The primary way in which Hyaluronic Acid functions is by reducing water loss from the skin. It acts as a cushion and lubricant in the joints and other tissues. It is a clear substance that is produced by the body naturally and is part of the extracellular matrix (ECM) the skin’s protective barrier. It helps to retain collagen, increase moisture, and provide elasticity and flexibility. In other words, HA keeps us looking young! Many people report that their skin feels “dewier,” that the bags under their eyes diminish and that their skin texture is smoother after applying serums containing hyaluronic acid.
Size and application
The size of different HA molecules is critically important for hyaluronic acid’s various functions. Larger molecules are found in healthy tissue and help keep inflammation, free radical damage and dehydration under control, whereas smaller polymers of HA can send distress signals to the immune system and raise inflammation to help with injury or wound healing. In fact, as well as being a super hydrator, HA is beneficial for treating cold sores, mouth sores, ulcers, bites and burns due to its ability to keep damaged tissue moist. And because it is a naturally occurring substance in the human body there is little risk of a reaction.
Aging is triggered by both intrinsic and extrinsic factors, meaning daily environmental exposure to pollutants and UV light, along with the normal process of aging. Studies show that there are multiple sites in the skin involved in the control of HA synthesis, deposition, cell and protein association and degradation. As we get older skin cells lose their ability to bind and retain water. Dryness occurs and this is when wrinkling begins. Additionally, wrinkles and fine lines are usually more visible in low humidity compared to high humidity environments because they further reduce the water-holding capacity and elasticity of the skin. Hyaluronic Acid can help all these situations by naturally reducing signs of aging and cutting epidermal water loss associated with environmental exposure and the normal aging process.
HA has been referred to as “the key molecule involved in skin moisture” and in the past decade scientists have been able to create technology-advanced HA formulas that are capable of really seeping below the skin’s surface. Recent studies show that topical application of advanced (low molecular weight) HA serums can improve skin moisture and lead to significant reductions in wrinkle depth within just several weeks.
To summarize, Hyaluronic Acid, because of it compatibility with just about every skin condition is a must have tool to add to your beauty box. Look for formulas that have more than one type of HA. This ensures that your skin will benefit topically and also see results at a deeper level over time.
Here’s how nighttime is the right time for the skin to reboot, repair and refresh
By day, the body protects itself; by night, the body repairs itself. As aesthetic professionals we are constantly reminding our clients about the importance of their before-bed skincare ritual to piggyback onto this physiological phenomena.
So what exactly does the skin get up to when we are out cold in the Land of Nod (or as we British compatriots like to say, “Off to Bedfordshire”)?
Keeping the Beat
The circadian rhythm is a 24-hour cycle that regulates the bodies of all living creatures. In humans, it is often referred to as the ‘body clock’, for it tells us when to sleep, rise, eat, regulating many physiological processes. When we find ourselves getting hungry or sleepy at the same time each day, that’s the circadian rhythm at work.
Everyone has a slightly different circadian rhythm – hence Larks (morning people) and Owls (night people) – but the average length is 24 and one-quarter hours. Back in 1981, Charles Czeisler, MD, PhD, FRCP of Harvard Medical School showed that daylight keeps a person’s internal clock aligned with the environment. This means that those who are most comfortable staying up late have naturally longer circadian rhythms than those who prefer to jump out of bed at the crack of dawn.
Generally, left to their own devices (that is, with no caffeine, party drugs, adrenaline or undue stress interrupting things), our bodies’ circadian sleep mode pattern kicks in around 9:00 pm.
Researchers also know that melatonin, the sleep hormone that protects the skin from pollution and sun damage during the day, begins to activate about this time signaling that it is time to wind down.
Then later as we sleep, serious skin revival and repair processes really kick in including increased production of HGH, the human growth hormone that helps all tissue repair and regenerate, as well as enhanced cell turnover.
So how can we as skincare professionals design our client’s nighttime skin care regime to capitalize on all this activity and ensure that the skin is refreshed and restored by morning?
Start by advising your clients on a few strategies and remember to remind them to treat their neck and décolletage at the same time.
• Leverage the 9 p.m. skin receptivity window: According to Anna Persaud, CEO at This Works, a skincare company based in the UK that pays particular attention to circadian rhythms and how they affect the skin, “The mid-evening phase, around 9 p.m., is when the skin is most able to absorb topical treatments and DNA repair is boosted.” So, even if your client doesn’t generally go to sleep until midnight, if she’s in for the evening, advise her to perform her abolitions at this time.
• Remove, rinse and repeat: Double cleansing at night is an absolute necessity no matter where you live because of today’s polluted atmosphere. Using two types of cleanser has become popular for good reason. Applying an oil-based product or micellar water first to gently remove make-up, followed by a deep pore cleanser that can be washed off, is an efficient way to make absolutely sure the skin is scrupulously clean. This is essential if your client uses mineral based cosmetics – which I love and recommend – but have found they can adhere to the skin more than conventional formulations.
• Exfoliate as needed: Adding an exfoliating product or mechanical cleansing brush (like a Clarisonic) to the routine is also very helpful; two to three times a week for sensitive skin and more often for normal. For those with super-sensitive or rosacea-prone skin, I recommend avoiding exfoliating directly around the nostrils as this area tends to redden and flair. Just make sure the client keeps the brushes properly cleaned after each use and changed on a regular basis.
• Don’t forget to tone: I always recommend toning after cleansing to make sure not a scrap of anything remains on the skin and to restore the pH. Toning can also add a little extra hydration for those with extra dry skin.
Aesthetician’s Tool Box
Figuring out what products to recommend is where your skill and experience come to the fore. Each client is individual, of course, with skin that responds differently to products and ingredients. Here are my favorite ones that enhance the skin’s natural ability to regenerate itself.
• Retinol to boost collagen production and speed cell renewal. Well reputed to aid in exfoliation, topical retinol products can be sensitizing so advise your clients when first starting with this to use once or twice a week initially to build up the skin’s tolerance.
• Antioxidants to fight free radical damage. Our bodies naturally contain antioxidants that neutralize free radicals in enzymes like superoxide dismutase, catalase and glutathione peroxidase. There are also smaller non-enzymatic antioxidants like vitamins C and E, coenzyme Q10 (ubiquinol) and glutathione. However, these natural mechanisms can become overwhelmed if too many free radicals are present, which is where the idea of topping up with antioxidant-containing products comes in. Great options to boost stability include Vitamins C and E, ferulic acid, green tea, lutein, lycophene, and resveratrol.
• Niacinamide (Vitamin B3) to boost the skin’s ability to fight pollution from the outside and counteract daily stress from the inside.
• Peptides to promote collagen production. Composed of amino acids, peptides form a vital part of the skin’s biological signaling mechanism. They carry information to the cells and stimulate fibroblast activity. In serum form, Matrixyl 3000, argiriline and pentapeptides are three options that have proved most effective.
• Stem cells to speed cellular repair. The advantage of plant-derived stem cells is that they are unspecialized or meristematic, until they receive a signal from the host plant to differentiate or change. Meristematic cells are generated from a defense response from the plant when it is cut. The responding callus contains stem cells that are now neutral. As they carry the entire DNA gene expression of the plant, they can turn themselves into any particular cell that is needed to heal or regenerate. At this stage these cells are cultured in the laboratory, become a usable active ingredient that eventually, when applied topically can protect against free radical damage caused by pollution, UV exposure, inflammation and photoaging. And the results can be dramatic. Smoother, toned skin with improved elasticity and firmness. Green apple, edelweiss, gardenia, sea fennel, grape and lilac are all great options.
• ATP to support cell metabolism. Known as the “energy currency of life”, adenosine tri-phosphate is a coenzyme that stores energy and improves microcirculation while restoring suppleness, radiance and firmness to the skin.
• Hyaluronic acid and ceramides to fortify the lipid barrier. While we are sleeping, the skin becomes more permeable and consequently is more receptive to all these fabulous ingredients above. This is obviously a good thing. However, the downside is that it works both ways. Permeable skin can easily become dehydrated through loss of moisture particularly in dryer, hotter or especially chilly climates where one sleeps with the air conditioner or heater on all night. Hyaluronic acid and ceramides are both natural components in human skin and are compatible with every complexion type needing a boost in the hydration department.
Getting enough sleep is a challenge for many of us these days and your clients will appreciate your suggestions. I recommend printing this list off to hand out to them on their spa visits.
• Expose yourself to lots of bright, natural light during the day. Getting outside each day, even if it’s a quick 20-minute walk, will boost ability to sleep at night as well as your lift your mood and alertness.
• Set regular bed and wake times whenever possible.
• Avoid hot baths just before bed.
Contrary to popular belief, a steaming bath can interfere with sleep by heating up the body’s core temperature. At bedtime you want to cool down. If you love that scalding soak in the tub, make sure you have it at least one hour before getting under the sheets.
• Keep your bedroom screen-free.
This is a hard one for many of us, but banishing the laptop, TV and mobile phones is one of the best things any of can do for our skin, our health and our stress levels. Exposure to the blue light these devices emit can inhibit the release of melatonin dramatically. If you can avoid looking at bright screens one to two hours before bedtime, the difference in both your skin and your mood will be dramatic.
• Sleep on your back if you can manage it.
Lines, wrinkles and puffiness literally get pressed into faces that sleep smashed into a pillow.
• Slip on a silk pillowcase.
While sleeping on our backs is better for us, for many it’s just not doable. So to avoid those deep creases and puffy eyes, a silk pillowcase can help. These are also great for the man in your life to help prevent ingrown hairs.
• Use lavender or chamomile pillow sprays.
This lovely touch can be very effective to help you fall asleep more quickly. Inhaling the aromas with a deep breathing exercise for just a few minutes quiets the mind and allows you to slip into a deep restful slumber.
• Careful with the alcohol.
Alcohol can interfere with a good night’s rest so have that glass of wine earlier in the evening. A glass of water before bedtime will also help to keep the skin hydrated while you sleep and nuts, especially almonds and walnuts, add oil and therefore moisture to the body and skin.
• Enjoy a light snack before bedtime.
This one is from the inestimable Anna Persaud who says, “Go for foods rich in tryptophan like turkey, chicken, pumpkin seeds and bananas.”
I cannot underestimate the importance of putting nighttime to work for maximum skin health and beauty. When a client is compliant, that’s when the results can be really remarkable. A motivated client recognizes that she is in a partnership with us, the aesthetician, to bring out the best in her skin. We know that what they do for their skin every day – and every night – is as important as what we do for them once a month when they visit us in the salon. Clearly, it makes all the difference in the world.
What is an LED?
You may well ask how light treatments can actually benefit the skin. I am talking about the LEDs (light emitting diodes) that seem to be popping up everywhere. Truthfully, it took me a while to be assured of the benefits. However, at SkinSense we have found that both blue light and infrared light therapy can be really effective at treating acne, eczema, rosacea and even aging.
Blue light therapy kills the acne-causing bacteria known as Propionibacterium acnes, or P acnes, which is found in the sebum and oil glands of the skin. These bacteria can cause inflammation and breakouts on the skin surface. The good news is that P acnes is sensitive to blue light and can actually be eliminated with this kind of therapy. Coupled with proper cleansing and treatment regimens the blue light offers a safe alternative to antibiotics and harsh topicals.
Red light therapy has a different function to blue light. It can speed wound healing and stimulate collagen production, promote firmness and improve skin texture. Additionally, red and blue light treatments can be used together on acne conditions to heal the skin, diminish scarring and reduce inflammation.
At SkinSense we have been using the hand held units during our facial treatments to great effect and have also been retailing them to many clients for home use. It is great to have a zit zapper that can get rid of pimples and breakouts at your fingertips! We have also found that by using the blue light at home, clients are less tempted to pick their skin because the breakouts clear up quickly and don’t leave a mark. It only takes minutes a day to treat each area.
Light therapy is painless, non-invasive and requires no recovery time. Both red and blue lights can be used on all skin conditions and ages and has no side effects. So on your next spa visit ask about our LED treatments and maybe consider adding a hand held unit to your skincare routine at home.
If you want healthy skin, the best place to start is with a healthy lifestyle and an excellent skin care routine. Nutritious food, adequate sleep, regular facials and good quality skincare products are the building blocks for maintaining a glowing complexion that gets noticed. However, there is one often-overlooked factor in skin care that might be affecting the health of your skin—pollution.
Like it or not, pollution is a fact of modern life. When we talk about heavy pollution, many Asian cities come to mind. We have all seen images of people wearing masks to work every day in Beijing, Tokyo and Delhi. But the effects of toxic air are also being seen in many ways in western cities, like Paris, New York and London.
Closer to home, with the heat upon us in Los Angeles, the smog has returned and unfortunately, the fires. Plus, here in the southern part of California, we did not get the rain we anticipated earlier in the year, and that has added to the level of unfriendly particulates in the air. This toxicity is having a very detrimental effect on the quality of our lives here and worldwide.
The Bad News: The real culprits?
Traffic pollution is particularly bad for the skin. Tiny particles called PMs that contain nitrogen dioxide and other harmful chemicals have now been linked to cancer, wrinkles and aging. It has also been discovered that these particles can actually penetrate into the skin, stimulating the melanocytes which then produce an overabundance of pigment and brown spots. Additionally, there is evidence that toxins can increase the production of extra blood vessels which cause redness, irritation and rosacea. One final point to take into consideration is that pollution can actually heighten the intensity of UV light and cause even more damage to the skin tissue. Never have SPF’s and EPF’s been so important.
The Good News: What to do?
On the bright side, modern technology is not only helping us understand these issues but is coming up with some protective measures and great products we can use to neutralize the damage without all of us having to wear biohazard suits every time we step outside.
We need to get back to beauty basics in a serious way and that means paying great attention to our night-time rituals as well as our morning routine.
Double cleansing at night is now an absolute necessity in today’s polluted environment. A deep pore cleanser will remove the grime that builds on our skin during the day. Using two types of cleanser – an oil or cream based product before the deep pore formula – can ensure that every scrap of make-up is wiped off. This is very important if you are using mineral based make-up – which I love – but it can adhere to the skin more than traditional formulations.
Whatever routine you chose, make sure it is thorough. Adding a Clarisonic brush to your cleansing routine is very helpful. For sensitive skins I would recommend only 2-3 times a week; less sensitive, once a day. And I am a huge proponent of following with a toner. Toners re-establish the pH of the skin and prepare the way for hydration and treatment products. Night-time cremes and serums should be an area where you invest more time and money. Alternating products that contain Retin-A, hyaluronic acid, vitamin C and other anti-oxidants, peptides, ceramides, stem cells and AHA’s really makes a difference to how the skin ages but don’t overdue the exfoliating. We need to protect our skin barrier as much as possible these days and being over aggressive can create vulnerability to the environment. This is an area where your aesthetician can advise you and work out a routine that gets the best results.
Add Niacinamide – vitamin B3 – to your EPF ingredient list ( environmental protection factor.)
Switch to mineral cosmetics on top of your SPF to add an extra veil of protection during the day.
Use an air purifier at night to reduce indoor air pollution.
Change pillow cases at least twice weekly.
Continuing research will provide more ways to protect us from the damaging effects of pollution but taking steps now will make a big difference to how healthy our skin will be as we age.
After working out, shower immediately. Cleanse the face and apply a hydrating sunscreen before leaving the gym. Running errands straight away without doing this causes breakouts and irritation.Clients prone to back breakouts should bring a clean t-shirt to change into.
Always cleanse your skin in the morning. During the night your skin goes to work repairing itself and absorbing the treatment products you have applied before bed. And there is such a thing as indoor pollution that can be equally as unhealthy as outdoor. So a gentle cleanse in the morning gets rid of any residue and gives you a fresh start.
Never go to sleep without cleansing off the day’s make-up and pollution. According to the Society of Cosmetic Chemists, every night you don’t cleanse your skin, you age three days more quickly. And yes, I am trying to scare you into the bathroom!
Always exercise before a facial – working out afterwards can cause additional break-outs.
Wipe off your cell phone several times a day. It attracts dirt and make-up that can cause clogging. Have a special holder for your phone so that it stays cleaner and is easier to find.
Always wash your hands before cleansing your face.
Tools to Help:
Carry travel sizes of cleanser, toner and moisturizer/SPF in your gym bag and a clean t-shirt.
Store wipes in your bag to keep your cell phone clean. Hand sanitizers can work too.
Use ear buds whenever possible.
As we all know, oxygen is essential for life. It makes up about 20% of the air we breathe, depending on where we live. But it is important when discussing skincare treatments to differentiate between oxygen entering the body through respiration versus the benefits of topically applied oxygen. When applied in too large amounts to the skin, oxygen can have a detrimental effect and produce free radicals.
However, at SkinSense we use a controlled and measured delivery system that enhances penetration without forming free radicals.
This solid state oxygen treatment uses no hydrogen peroxide or gas wands and all the activity is generated by enzyme action which suits a variety of skin conditions.
Here are the main benefits:
Stimulates collagen production by increasing cellular activity. This reduces the appearance of fine lines and wrinkles.Calms rosacea and acne by reducing bacteria levels on the skin surface.
Ideal for deep cleansing clogged, congested and acneic conditons.
Speeds recovery after laser treatments, peels and microdermabrasion.
Facilitates the absorption of active ingredients applied after treatment.
Tightens the skin surface and leaves the complexion glowing and refreshed.
Oxygen can be performed as regularly as once a week, but results are evident after just one treatment. In other words oxygen facials are the perfect tool to combat the pollution and stress of city life and provide all of us a welcome opportunity to have a continually healthy, glowing complexion.
Today we have some great tools available to tackle the aging process on both the top and in the deeper layers of the skin – all in one session.
At SkinSense, microcurrent has become a very popular electrical protocol that we offer to all our clients interested in keeping the skin firm, toned and youthful. Originally used in the medical field to treat stroke victims, Bells Palsy and for pain relief of injured muscles and tendons, we perform microcurrent as a stand-alone treatment or as an add-on to other facial protocols.
Here are the main benefits:
Tightening – the low-level electricity combines with our bodies’ own electrical impulses to trigger movement – rather like taking your skin to the gym for an exercise session.
Glucose production – microcurrent can also trigger a chemical reaction at a cellular level that enhances the production of ATP (Adenosine Triphosphate) by almost 500%. This is the fuel that energizes all cellular activity in the body and is essential to cellular health.
Microcurrent has a very calming effect on Rosacea and skin which tends toward redness and irritation.
It can also soften scar tissue, improve circulation and get rid of puffiness by stimulating lymph flow which clams environmental sensitivity and allergies.
Topically, AHA’s (Alpha Hydroxy Acids) can be naturally derived but in skin care today are mostly synthetically produced. The most popular AHA’s are Lactic and Glycolic acids and we also use Mandelic acid at SkinSense.
The main benefits are:
Treatment of sun damaged skin and pigmentation.
Normalizing hyperkeratinization – skin that appears over–thickened and dull.
Increase in exfoliation of dead skin cells which tends to slow with aging.
This combination of topicals and electricity has an immediate effect on the skin – benefits that make the skin appear immediately youthful and radiant and that also last long past the day of treatment. We are currently offering this combination treatment for $130.00 – a savings of $70.00 – so book now and Spring forward with a magical glow!
I get asked this question by a client at least once a day at the spa… Are home skin care devices just for people who can’t afford a facial or maybe are too busy to go to the spa? Will I get the same results I get here at Skin Sense?
Technology is always changing and improving. Ultrasonic cleansing brushes and hair removal devices have had the best track record so far according to Philips and Wendy Lewis & Co Ltd., two global aesthetics consultancy companies who track these devices. That might be because results are immediately tangible – less hair, cleaner pores – and fit easily into one’s daily routine – cleansing and shaving.
Anti-aging devices are a little harder to assess and some are so high-tech that they need FDA approval. Many of these devices are quite costly as well ($500.00- $1,000.00.) They also need to be used 10-15 minutes a day for several weeks before seeing results. And some of the more sophisticated devices could potentially damage your skin if used incorrectly or on the wrong skin type/color.
Maybe most important – how many times have any of us purchased workout equipment with the best of intentions only to have it collecting dust three months later? Compliance and consistency are your skin’s best friend. I think only the most disciplined and leisurely of us could comply with the recommended use of these home devices. And honestly, isn’t a relaxing 75 minute treatment at Skin Sense where we use the most cutting edge and proven electrical equipment more appealing and doable for the majority of us? See our post “Electricity R” post.
So in conclusion, I don’t think we have reached the point where the fountain of youth can be found in our bathrooms or anywhere at home. But I do think that at home devices, once proven safe and effective, can be used by the disciplined client as an adjunct to a regular skincare routine while prolonging the benefits gained from regular visits to Skin Sense.
Do you get an occasional pimple or are you dealing with full blown acne? With the help of our in house acne expert, Nancee Daly, we have comprised a list to keep your skin clear and healthy any time of the year.
No HOT yoga when dealing with acne. Yoga practice is great for keeping the mind and body de-stressed which in turn controls hormonal activity. But HOT yoga, where there is excessive heat and sweating can cause more break-outs and irritate an already unbalanced skin. Heat also ages the skin so keep it cool.
Probiotics, as already mentioned, help to restore some of the healthy bacteria (Microbiota) that antibiotics can wipe out. The Microbiota are essential for maintaining our immune systems so find a probiotic formula that contains at least 50 billion cultures and as many bacteria strains as possible.
Cleanse thoroughly every night – if necessary two to three times before toning and make sure that the cotton pad you use to tone is completely clean before moving on to the rehydrating and rebalancing phase.
Add a holistic approach with Reishi mushrooms, red clover, peppermint, saw palmetto, black cohosh and green tea. These all control the presence of androgens and can reduce the severity of acne.
Watch the sugars in your diet. Simple sugars in particular are highly inflammatory. Candy, sodas, ice cream, alcohol and white foods are the main culprits. Dairy foods can also exacerbate acne and check that any supplements that you are taking do not contain iodides.
We recommend that our male clients sterilize their razors after each use and that our female clients make sure that every trace of make-up is washed off at the end of the day. This often means several cleansing steps and plenty of toning.
Make-up brushes should be washed every week and most important NO PICKING!! Check out my post “Stop picking on me”. When a painful break-out begins to erupt, ice it for 15 minutes 2-3 times a day. This will not only help to reduce the severity but also the scarring.
Change pillow cases at least twice a week and wipe off smart phones with an antiseptic wipe after each use.
Finally make sure you hydrate inside and out. Plenty of water keeps the system flushed and healthy and a light topical serum or hydrating lotion will help to rebalance the skin. Don’t eliminate moisturizers. The right one will help, not hinder, the healing process.
Hormones and acne:
Puberty is often associated with acne break-outs and at SkinSense we regularly counsel teenagers about skin hygiene and sensible dietary choices as we clean their skins. But many male and female clients develop acne later in life after navigating puberty and pregnancy without any problems. This can be due to excessive stress and in women it frequently signals approaching menopause, as estrogen levels drop allowing more free testosterone to take control.
Tip: Spironolactone (Aldactone) is an effective oral androgen blocker that helps to control this kind of late onset acne. (For women only.) Ask your doctor for details.
The formation of an acne lesion occurs when the skin is oily and begins to shed excessively, clogging the pores and supplying a food source for Propionibacterium (p. acnes). This creates inflammation and an immune response.
Identify the type:
Comedonal, Inflammatory and Cystic acne are the main categories used to define this condition. For the first two, a mix of topicals including salicylic, lactic and glycolic acids, with tea tree and camphor for spot treatment is very effective. Sometimes oral antibiotics are necessary to treat inflammatory acne but don’t stay on these for too long and always take a good probiotic at the same time. The redness and scarring is easily treated with an over the counter or prescription retinoid. Build slowly – one or two nightly applications a week – to avoid irritation and always wear a sunscreen during the day.
With both Comedonal and inflammatory acne regular cleaning and rebalancing facials are really helpful to bring the breakouts under control. At SkinSense, we often use a Mandelic Acid peel and an enzyme treatment that incorporates Niacinamide and Pumpkin extract to get rid of scarring. Oxygen facials are also great for a deep clean, killing bacteria, calming and revitalizing the skin.
Cystic acne is a more serious type of acne with deeper inflammation and a higher risk of scarring. It needs to be tackled quickly. If after three months oral anti-biotics don’t do the trick then Accutane is often recommended. Aczone is a topical medication that is non-irritating, reduces inflammation and can be used along with Accutane. Accutane does have some potential risks for certain individuals so make sure your dermatologist explains these to you and monitors you closely while you are on the medication. Gentle cleaning facials are useful in these cases to clear the skin and calm any redness.If Accutane is not a choice you would make, then there are other options and lifestyle plays an enormous role in how you can rebalance and correct acne.
