Glycolic acid is an organic substance with the chemical formula C2H4O3, a colorless and deliquescent crystal. Soluble in water, soluble in methanol, ethanol, ethyl acetate and other organic solvents, slightly soluble in ether, insoluble in hydrocarbons. It has the dual nature of alcohol and acid, and decomposes when heated to boiling point. For organic synthesis, etc.
Glycolic acid is a chemical substance belonging to the group of fruit acids or alpha-hydroxy acids, obtained from sugar cane and therefore can also be considered a natural substance. Citric acid from limes or other citrus can also be classified as glycolic acid. Glycolic acid works by breaking the bonds of those old skin cells that are no longer needed, which can clog pores and make skin look dull. Many people's skin looks more revitalized after using glycolic acid.
Glycolic acid can exfoliate because it is highly acidic and dissolves easily. When a cream or gel containing glycolic acid is used on the skin, it penetrates into the underlying layer of damaged skin, extracting dead cells to the surface of the skin and removing them, resulting in a smoother and more youthful appearance of skin. The second benefit is that it provides hydration to the newly exfoliated skin surface. That's why some skincare counters sell a full range of beauty resurfacing products. Other moisturizing and neutralizing ingredients in the AHA line can counteract the corrosive properties of glycolic acid.
Just like with other exfoliants, you should start small and see how this works on your skin. If you have sensitive skin, it is even more important to take extra care or contact a dermatologist before use. Glycolic acid containing cleaners may be a good method to use if you are testing for the first time. Once you know you're doing well with your cleanser, you can move on to other products. You can also start with a lower percentage glycolic acid product and see how your skin reacts.
Are there more benefits to higher percentage glycolic acid toners? Often, a higher percentage of product can equate to more visible or faster results, but it can also increase skin sensitivity. This is why strong glycolic acid peels are often performed under the supervision of a professional, which is not so often (such as once a month). As long as it is used correctly and in the right concentration, the cosmetic peeling effect of glycolic acid is good.
