Glycolic acid, an alpha-hydroxy acid (AHA) derived from sugarcane, is frequently utilized in skincare formulations for its exfoliating properties. The timeframe for observing noticeable changes from consistent glycolic acid use varies based on factors such as concentration, frequency of application, individual skin type, and the specific skin concern being addressed, such as fine lines, acne, or hyperpigmentation.
The benefits of glycolic acid stem from its ability to loosen the bonds between dead skin cells on the surface, promoting cell turnover and revealing brighter, smoother skin. Historically, AHAs have been recognized for their rejuvenating effects, with early uses documented in cosmetic preparations dating back centuries. Modern applications have refined the formulation and delivery of glycolic acid, leading to a wider range of accessible and effective products.
