What is glycolic acid?
This is a type of alpha hydroxy acid (AHA), a natural acid found in fruits such as sugar cane, lemon, and melon. It is water soluble, commonly used in skin care and has the ability to gently exfoliate the skin. “Glycolic acid works by removing dead skin cells from the surface, which helps to tone the skin and improve the texture of the skin,” says dermatologist Dr. Shareefa Chause. It also helps reduce signs of sun damage. Known for its benefits of peeling, hydration and anti-aging, it is one of the most popular AHAs used in skincare, according to a study published in the Journal of the European Academy of Dermatology and Venereology.
What are the advantages of glycolic acid?
Common skin benefits of using this acid include:
1. Moisturizes the skin
It helps to keep your skin nourished and hydrated. “It is known as a humectant because it pulls water molecules from the air into the skin, making them softer and more hydrated,” says Dr. Chaus. This is useful for people with dry or dull skin.

2. Promotes peeling
One of the most famous benefits of glycolic acid is its release. It helps to remove the top layer of dead skin cells. This will help your skin work better as it will make your skin smoother and allow other skincare products to get deeper into your skin.
3. Treat acne
It is also useful for people with acne. It keeps pores clean and removes oils and dirt that can cause breakouts. A study of journal molecules found that glycolic acid has antibacterial and antioxidant properties. These can reduce acne and improve the overall appearance. “It also causes the skin and produces more collagen, which makes the skin plump, stiff and elastic,” explains Dr. Chaus.
4. Reduce thin lines and wrinkles
As we age, our skin can reduce collagen and lead to thin lines and wrinkles. According to a study published in the Journal of Dermatologic Science, this ingredient helps stimulate collagen production.
5. Fade hyperpigmentation
If you have dark spots or uneven skin tones, glycolic acid can help fade them. Removes dark, damaged upper layers of the skin and reveals a lighter skin tone. Glycolic acid peels are often used to fade hyperpigmentation.
6. Brighten the skin
This acid can make your skin look fresh and radiant, as it removes dull and dead skin cells. Not only this, it also helps to increase skin moisture levels and provides gentle peeling–All of these help your skin shine and look evener.
7. Fight against the damage of the sun
Too much sun can cause dark spots and aging. A Journal of Cosmetic Dermatology study showed that glycolic acid is useful in treating sun-impaired skin. It functions gently without causing irritation or redness.
