Glycolic acid is perhaps best known acid of a group of chemicals called fruit acids or alpha hydroxy acid (AHA). It is derived from sugar cane, so it can be considered a natural product. Citric acid from oranges and other citrus fruits are also included in the same classification as glycolic acid.
Industrial uses include glycolic acid for rust removal and degreasing. Glycolic acid in its pure state (usually sold in concentrations of 70% or more) is extremely dangerous to exposed skin. In fact, the government considers any product with a glycolic acid concentration of more than 10% can be a hazardous material.
Importantly, glycolic acid not only has industrial uses, it also has cosmetic uses. Glycolic acid is generally used as a natural skin exfoliant and a moisturizer, although there is much debate about its safety and efficacy.
Some advocates suggest that glycolic acid products glycolic acid concentrations less than 10% are practically useless. The problem is that many cosmetic manufacturers scale do not increase the levels of glycolic acid, fearing liability action lawsuits. Some smaller companies of cosmetics offer customers high-end products with at least a 10% concentration of glycolic acid ..
Glycolic acid acts as an exfoliating agent because of its high acidity but easy solubility. When placed on the skin as part of an exfoliating cream or gel, glycolic acid goes under the upper layers of damaged skin and destroys the “glue” that holds dead skin to the surface. The dead skin is chemically burned, then you have to rinse with water and neutralize the remaining acid.
The result is a surface of the skin very smooth and more youthful appearance. A secondary benefit is the ability to produce glycolic acid moisturizers to him freshly exfoliated skin. Therefore, cosmetic manufacturers often sell a complete system of skin care , a line containing alpha-hydroxy moisturizers and neutralizers to counteract the corrosive effects of glycolic acid.
The organic cosmetic exfoliants and moisturizers containing glycolic acid may leave the sun-sensitive skin, skin experts recommend as much care as using a sunscreen after exfoliating with glycolic acid. If a concentration of 10% glycolic acid can cause concern for skin damage, diferentte other use may be even more controversial.
Some users looking for a more complete exfoliation may opt for a chemical peel. In general, chemical peel involves thorough washing of the skin followed by an application of a powerful AHA such as glycolic acid. Concentration levels of glycolic acid chemical peels can be as high as 50% or more. Even industrial suppliers of glycolic acid concentration limit of 70%, so this is actually a very powerful chemical process.
Very often after a chemical peel, the skin of the patient will look like it was sunburned. Several days of recovery are often necessary for full recovery of a glycolic acid peel. Glycolic acid Advocates say the process may seem dangerous or unpleasant, but the results are worth the temporary discomfort.
Whether or not the miracle ingredient glycolic acid or the fountain of youth , there can be no doubt that it is effective when used correctly and at the appropriate concentration level for exfoliation and hydration needs of an individual.
