Alpha Hydroxy Acid
Description
Alpha Hydroxy Acids (AHAs) are a class of chemical exfoliants derived from natural sources such as fruits, milk, and sugarcane. These water-soluble acids work by dissolving the bonds between dead skin cells, promoting cell turnover and revealing fresher, smoother skin beneath. Common types of AHAs include glycolic acid, lactic acid, and mandelic acid, each with varying molecular sizes that affect penetration depth and potential irritation.
AHAs offer multiple benefits for skin health and appearance. They effectively reduce the appearance of fine lines, wrinkles, and hyperpigmentation by accelerating skin cell renewal. AHAs also improve skin texture, unclog pores, and enhance the absorption of other skincare products. Additionally, they stimulate collagen production, contributing to firmer, more youthful-looking skin over time.
Concentration levels in skincare products typically range from 5% to 30%, with higher concentrations reserved for professional treatments. It's crucial to introduce AHAs gradually into a skincare routine to minimize potential side effects such as redness, dryness, or increased sun sensitivity. Sunscreen use is imperative when incorporating AHAs, as they can increase photosensitivity. Regular use of AHAs can significantly improve overall skin tone, texture, and clarity.
