Glycolic acid, derived from sugarcane, has the smallest molecule size of all AHAs, allowing it to penetrate the skin’s upper layers effectively. It breaks down bonds between dead skin cells, to reveal fresher, smoother skin underneath.

Frequently Asked Questions

What is an AHA?

AHA stands for alpha hydroxy acid: a group of water-soluble exfoliants that work on the skin’s surface to improve texture, tone and radiance. Common AHAs include glycolic, lactic and mandelic acid, each with unique properties. They’re often found in cleansers, toners and targeted treatments designed to reveal visibly smoother, more luminous skin.

Is glycolic acid considered an AHA?

Yes, glycolic acid is one of the most well-known alpha hydroxy acids, or AHAs. Naturally derived from sugar cane, it is celebrated for its small molecular size, which allows it to penetrate the skin effectively and deliver noticeable results.

What does glycolic acid do for the skin?

Glycolic acid works by gently dissolving the bonds between dead skin cells on the surface of the skin. This encourages smoother texture, a brighter complexion and better absorption of other skincare ingredients. With regular use, it can help reduce the appearance of fine lines, uneven tone and dullness.

Can glycolic acid be used with retinol?

While both ingredients are powerful on their own, using glycolic acid and vitamin A together requires caution. They are best introduced gradually and used on alternate nights to avoid irritation.

Medik8’s barrier-supportive formulations are designed to minimise the risk of sensitivity when combining actives, but it’s important to follow professional guidance and pay attention to how your skin responds.

Can I use glycolic acid every day?

How often you use glycolic acid depends on your skin’s tolerance and the strength of the formula. While some lower-strength products can be used daily, stronger concentrations are best introduced gradually, often just a few times per week.

Medik8’s Sleep Glycolic, for example, is designed as a weekly booster to deliver visible results with minimal irritation. Always follow product guidance and give your skin time to adjust.
