Glycolic Acid

Glycolic acid is one of the most popular alpha hydroxy acids (AHAs) used in UK skincare. It is a small, fast-acting acid that gently exfoliates the surface of the skin, helping to reveal smoother, brighter and more even-toned skin. Ideal for those looking to improve texture and radiance without harsh scrubbing.

How it works in skincare

In cosmetics and skincare, glycolic acid works by loosening the bonds that hold dead skin cells together on the surface of the stratum corneum. Its tiny molecular size allows it to penetrate quickly, encouraging natural cell turnover and leaving skin looking fresher and more refined. It is commonly found in cleansers, toners, serums, masks and professional peels at varying strengths.
