Glycolic acid is a type of alpha hydroxy acid (AHA) that is commonly used in skincare products due to its exfoliating properties. It works by removing the top layers of dead skin cells, which can help improve skin texture, tone, and radiance. Glycolic acid is also known to stimulate collagen production, which can help reduce signs of environmental damage and accelerate skin healing. Some of the common uses of glycolic acid include:
- Acne: Glycolic acid can help unclog pores and reduce the appearance of acne.
- Aging skin: Glycolic acid can help improve the appearance of fine lines, wrinkles, and age spots.
- Dark skin patches: Glycolic acid can help reduce the appearance of dark patches on the face.
- Acne scars: Glycolic acid can help reduce the appearance of acne scars.
- Stretch marks: Glycolic acid may help improve the appearance of stretch marks, although there is no good scientific evidence to support this use.
- Dry skin: Glycolic acid is a humectant, which means it attracts and binds water to skin cells. It can help hydrate dry skin and improve its texture.
- Flaky scalp: Glycolic acid can help with dry skin on the scalp and improve its texture.
Its important to note that glycolic acid should be used in products containing concentrations of 10% or less, as higher concentrations can cause serious skin reactions. Additionally, because glycolic acid exfoliates the skin, it can increase its sensitivity to the sun, so its important to wear sunscreen daily during treatment and for at least one week afterward.
