Glycolic acid’s efficacy is not instantaneous; discernible changes in skin texture and appearance require consistent application over a period of time. The specific timeframe for visible results varies depending on several factors, including the concentration of the glycolic acid product, the frequency of use, the individual’s skin type, and the specific skin concern being addressed. For example, a glycolic acid cleanser may yield subtle improvements in skin brightness within a few weeks, while a higher-concentration peel applied by a professional might produce more dramatic results within a shorter timeframe.
The appeal of incorporating glycolic acid into skincare routines lies in its ability to exfoliate the skin, revealing newer, healthier cells and promoting collagen production. This results in benefits such as reduced appearance of fine lines and wrinkles, improved skin tone, and diminished hyperpigmentation. Historically, alpha-hydroxy acids (AHAs), including glycolic acid, have been recognized for their skin-rejuvenating properties, leading to their widespread use in cosmetic formulations and professional treatments.
