Alpha Hydroxy Acid refers to a large group of natural acids with skin improving effects. They include glycolic acid, citric acid, lactic acid, tartaric acid, malic acid and mandelic acid, which are derived from natural sources such as fruits, sugar canes and milk.
How does Glycolic Acid work?
By dissolving sebum and other substances that bind skin cells, glycolic acid enables skin to naturally peel. By removing dead skin cells from stratum corneum (the outermost layer of the epidermis), skin is left smooth, fresh and more even toned. High concentrations of glycolic acid can brighten dark spots and even out hyperpigmentation. The natural acids also successfully treat sun damaged skin, and stimulate the production of collagen.
In general, glycolic acid is most effective at a concentration between 10% and 20%. Higher concentrations can be used in clinics as chemical peel treatments.
What can I expect when using Glycolic Acids?
Serveral clinical studies proves that glycolic acids successfully improves damaged skin. Fine lines, hyperpigmentation and rough skin is improved. Side effects can be redness, dryness and light irritation. Treatment with glycolic acids is suitable for more or less all skin conditions, except for some cases with eczema, rosacea and/or couperose. It is important to always use SPF during daytime while treating skin with glycolic acids.
