Topically applied, AHA’s ( Alpha Hydroxy Acids) can be naturally derived from fruits, plants and nuts but today are mostly synthetically produced. The most popular are Glycolic and Lactic which are especially suited for home application because they are less irritating. However spa protocols often include a combination of other AHA’s such as Mandelic, Citric, Tartaric and Malic.
Used to treat wrinkles, sun damage, age spots, pigmentation and acne, AHA’s gently exfoliate unnecessary dead skin cells on the surface of the skin that build up over time. This increases blood flow and allows for better product penetration.When used continuously Glycolic Acid in particular can brighten the skin and lighten pigmentation. It can also balance pH. Long term use has helped to reduce the appearance of scar tissue and can soften the appearance of fine lines and wrinkles.
For home use most AHA formulas contain 10% or less of the active ingredient. In the spa this percentage is often increased depending on the blend of AHA’s being used and also on the results that are required. Of course skin sensitivity is also taken into account.
It is really essential to use a daily SPF of at least 30 when using any products that contain Alpha Hydroxy Acids because they all make the skin much more susceptible to the sun and increase the likelihood of burning.
By applying toners, serums and/or creams to skin containing these ingredients you can improve the health and appearance of your skin significantly and ensure that healthy, youthful glow that we all yearn for.
