“I guess chemistry is just another word for love.” — Scott Thompson
Do you remember in 7th grade science where we would test vinegar and milk with a litmus paper and the paper would turn light pink or purple? Depending on the color that the paper turned that was it’s pH value. That’s how we first learned about the pH scale — the acidity and alkalinity of substances. We learned too how all these different acids and alkalines work together in our environment as well as our bodies to keep things running smoothly. Well, it’s the same thing with skin. That’s why it is not unusual to talk about the pH level of a skincare product.
The letters pH stand for potential hydrogen, as hydrogen is the element that controls the levels of either alkalinity or acidity in a formulation. Acidic products range from 0–6.9 and are often used to exfoliate or peel the skin; alkaline products range from 7.1–14 and can be used in cleansers or to neutralize acidity. Very often moisturizers are formulated to be neutral (a pH of 7) to bring the skin back into balance. Too much acid or alkalinity is irritating for the skin, so the pH is always carefully calibrated.
The optimal pH value of skin on most of our face and body lies between 4.7 and 5.75. As mentioned above a pH of 7 (that of pure water) is considered neutral. Anything below that is acidic and above it alkaline, so skin’s natural pH is mildly acidic. Skin maintains its barrier best around 5.5 — slightly acidic. At the ideal pH (5.5), the skin is able to maintain a good barrier (the acid mantle) and, together with natural oils, moisturizers and bacteria, function as a true protective defense organ.
More recently, the principle of pH balancing has been applied to our general wellbeing. This holistic approach believes that the foundation of healthy digestion is built on a simple eating system that maintains an ideal acid/alkaline (pH) balance in the body. 70% of the immune system is based in the abdomen and 90% of the tryptophan needed to make serotonin for the brain — essential to ensure we feel good — is made here. So in order to live a long and happy life it obviously pays to keep our abdomens happy!
As we all know, in the case of romance it is often quoted “the way to a man’s heart is through his stomach.” But what we are talking about here may not involve the foods and habits we are recommending!
And how does all this reflect in the skin? Well, too much acidity triggers eczema, inflammation, acne, boils, rosacea and wrinkles. So all of these conditions could be greatly improved by maintaining a more alkaline system. Obviously, exercise and relaxation are essential as well as drinking the right amount of water. Men need more water than women on a daily basis. If you eat plenty of vegetables and two or three fresh fruits a day, you can fill half your required fluid quota easily.
How do we do that? The suggested pH ratio would be a diet of two-thirds alkaline and one-third acid-forming foods. This takes some adjustment. So, to take a step in the right direction, let’s outline a few alkaline foods that we can incorporate in greater quantities and some acidic foods we can eliminate.
Raw, green leafy vegetables like chard, kale and spinach are all excellent alkaline-rich foods. So are avocados, celery, cucumbers, tomatoes, peppers, broccoli, coconut, cherries, grapefruit, lemons and watermelon. A healthy way to start and end each day with an alkaline system, for example, would be with a cup of warm water flavored with half a lemon. Also adding turmeric, garlic, ginger and flax seeds to your diet along with a good probiotic will keep the gut healthy and the skin glowing.
Things to avoid would be white flour, coffee, red meat, too much alcohol and artificial sugar. Also minimize your intake of fermented foods — they are acidic in nature. Stick to moderate amounts of sauerkraut, kimchi and pickles. These will add vitamins to your diet and anti-inflammatory benefits too.
