Glycolic Acid vs Other AHAs: What’s the Difference?
Glycolic acid is the most well-known and widely used alpha hydroxy acid (AHA) in skincare. Derived from sugar cane, it has the smallest molecular size among AHAs, allowing it to penetrate deeply and effectively exfoliate the skin. This makes glycolic acid highly effective for brightening skin, reducing fine lines, and treating acne. Its fast-acting nature makes it ideal for those seeking quick, noticeable results, especially for improving texture and radiance.
Other AHAs, such as lactic acid, citric acid, and mandelic acid, offer unique benefits depending on their molecular size and source. Lactic acid, for example, is gentler and more hydrating, making it suitable for sensitive or dry skin. Citric acid, often derived from citrus fruits, provides antioxidant properties, while mandelic acid, with a larger molecular size, is slower in penetration but ideal for sensitive skin. While glycolic acid is the most potent, other AHAs offer milder, more targeted solutions based on individual skin concerns. Therefore, choosing the right AHA depends on your skin’s needs and tolerance.
Potential Side Effects of Glycolic Acid
While glycolic acid offers numerous skincare benefits, it can also cause side effects, particularly if not used correctly. One of the most common reactions is skin irritation, which may include redness, itching, or a burning sensation, especially for those with sensitive skin. This irritation occurs because glycolic acid accelerates skin cell turnover, and overuse can strip the skin of its natural oils, leading to dryness or peeling.
