What is Glycolic Acid?

Various applications of alpha-hydroxy acid (AHA), better known as glycolic acid, a product obtained from sugarcane, have been popular in dermatology due to its potential and powerful skin-exfoliating property. Its tiny molecular size can enter deeper into the skin compared to other AHAs.

According to Dr. Fatima Saba, Dermatologist:

"Glycolic acid loosens the bond that holds dead skin cells together, so the skin that comes out is fresh and smoother underneath."

14 Clinically Supported Benefits of Glycolic Acid

1. Effective Exfoliant (Removes Dead Skin)

Glycolic acids will dissolve bonds on the tip of your skin cells, and as they break, they will distribute lighter skin. It will make your skin brighter and younger.

2. Brighter and More Even Skin Tone

It reduces dark spots, sun spots, and hyperpigmentation associated with acne. It contains an acid that promotes cell turnover.

3. Reduces Acne and Clogged Pores

Glycolic acid removes dead skin and debris from pores, which helps reduce blackheads and acne.

4. Collagen Production Stimulation

Prolonged usage can stimulate collagen production, thus enhancing elasticity and smoothing out fine lines and wrinkles.

5. Improves Skin Texture

It leads to smooth and soft skin as it boosts cell renewal.

6. It Treats Keratosis P

Its exfoliating effects may be useful in smoothing an uneven skin texture, as seen in keratosis pilaris.

7. Manages Photoaging Symptoms

Photoaging (sun-induced skin aging) presents with wrinkles, spots, and skin texture changes, and glycolic acid can be very useful against these.

9. Reduces Appearance of Acne Scars

Chemical peels with glycolic acid have been demonstrated to reduce acne scars as they occur regularly.

10. Ingrown Hairs Treatment

Peels can remove hidden hair and inflammation associated with it.

11. Reduces Stretch Marks (With Professional Peels)

It may also work on existing stretch marks by stimulating collagen production and encouraging new cells on the surface.

12. Can Hydrate Skin

While exfoliant acids can be drying, glycolic acid also increases hyaluronic levels in skin, supporting moisture retention.

13. Boosts Radiance & Glow

Exfoliation removes dull buildup, instantly revitalizing tired or stressed skin.

14. Versatile in Many Products

Glycolic acid is found in serums, toners, peels, and cleansers — each offering graded exfoliation for different skin needs.
