Lactic Acid/Glycolic Acid Copolymer is a type of cosmetic ingredient often used in skincare products for its beneficial properties.
To simplify, it's a kind of polymer, a large molecule made up of repeating subunits, in this case, lactic acid and glycolic acid. When they are combined, the resulting product is a compound that has different properties from the individual acids.
Lactic acid, derived from milk, and glycolic acid, derived from sugar cane, are both Alpha Hydroxy Acids (AHAs). AHAs are well-known in skincare for their exfoliating abilities. They help to break the bonds between dead skin cells, promoting cell turnover and resulting in fresher, brighter skin.
However, the use of AHAs can sometimes be harsh and irritating to the skin. This is where the Lactic Acid/Glycolic Acid Copolymer comes in. By linking these acids together in a polymer form, the overall effect on the skin is milder than with the individual acids. This allows for the benefits of AHAs without as much potential for irritation.
In summary, Lactic Acid/Glycolic Acid Copolymer is used in cosmetic formulations to:
- Exfoliate the skin gently: It helps to remove dead skin cells from the skin's surface, promoting cell renewal and revealing a brighter complexion.
- Improve skin texture: By promoting cell turnover, it can help reduce the appearance of fine lines, wrinkles, and skin roughness.
- Enhance product penetration: By removing the dead skin cells on the surface, it can enhance the absorption of other ingredients in your skincare products, increasing their effectiveness.
This ingredient can be found in a variety of skincare products, including cleansers, toners, serums, and creams, especially those designed for anti-aging, brightening, and skin-smoothing purposes. However, as with any exfoliating ingredient, it's essential to use sunscreen while using products containing this copolymer, as they can make your skin more sensitive to the sun.
