Glycolic acid is widely used in skincare for its ability to exfoliate, hydrate, and improve several common skin concerns[1]. Its main uses include:
- Exfoliation: Glycolic acid is a chemical exfoliant that removes dead skin cells, promoting smoother, brighter skin and unclogging pores[4].
- Acne treatment: By preventing dead skin buildup and unclogging pores, glycolic acid helps reduce and prevent acne and is also beneficial for body acne[3][6].
- Reduction of fine lines and wrinkles: Regular use of glycolic acid stimulates collagen production, which helps to reduce the appearance of fine lines and wrinkles and contributes to a more youthful skin appearance[1][5].
- Improvement of skin tone and texture: Glycolic acid helps to even out skin tone by reducing hyperpigmentation, dark spots, and melasma, leading to a brighter and more uniform complexion[1][3].
- Hydration: As a humectant, glycolic acid attracts water to the skin, improving moisture retention and supporting hydration[2][7].
- Reduction of acne scars: It is often used to minimize the appearance of acne scars by stimulating cell turnover and skin regeneration[3][7].
- Treatment of certain skin conditions: Glycolic acid can be used as part of professional chemical peels for managing conditions like keratosis pilaris and, in conjunction with other agents, warts[2][7].
- Minimizing the appearance of pores: By clearing out debris and excess oil, glycolic acid helps pores appear smaller and less noticeable[5].
Products containing up to 10% glycolic acid are generally safe for over-the-counter use, but higher concentrations should be used under dermatologist supervision to prevent adverse effects[3]. Individuals should start with lower concentrations and increase slowly, as some sensitivity or irritation can occur[2].
