Can You Use Retinol With Glycolic Acid?

OK with caution

Yes, but alternate nights instead of layering

Retinoids and AHAs are usually better on different nights. No harmful chemical reaction is known, but irritation adds up. Introduce slowly and watch your skin.

This verdict matches the rule in our ingredient conflict checker (rule last checked 2026-09-23).

You can use both, but layering glycolic acid and retinol on the same night is one of the quickest ways to irritate your skin. Alternate nights, and wear sunscreen every day, because both increase sun sensitivity.

How to use retinol and glycolic acid

Tick off each step as you go. Nothing is saved or sent.

What to watch for

  • Stinging, raw-feeling skin or visible peeling.
  • Sunburning more easily than usual.

Why this verdict

Glycolic acid is the most common alpha hydroxy acid (AHA). It loosens the bonds between dead cells on the skin surface. Retinol works through retinoid pathways to change how skin cells turn over. Their effects overlap enough that using both at once often means more flaking, stinging and redness than either causes alone.

Sun sensitivity is the other shared issue. The FDA says AHA products can increase sensitivity to the sun and the chance of sunburn, and recommends sunscreen, protective clothing and limited sun exposure while using them and for a week after stopping. Retinoids also increase sun sensitivity.

Prescription labels reflect the same concern for stronger retinoids. The Differin (adapalene) prescribing information says to avoid products containing alpha hydroxy or glycolic acids, and the tretinoin label advises caution with other topical products. Retinol is gentler, so we rate this pair "OK with caution" rather than "avoid", but if you switch to adapalene, drop the glycolic acid.

For acne, a 2020 Cochrane review found limited evidence for AHAs, and retinol is not an established acne treatment either. If your main goal is fewer breakouts, a proven acne treatment should come first, with extra exfoliants added only if your skin tolerates them.

About each ingredient

Retinol

A cosmetic form of vitamin A that skin converts toward retinoic acid. It is generally gentler and less potent than prescription retinoids. It is sold mainly for signs of aging; the evidence for it as an acne treatment is much thinner than for adapalene or tretinoin.

Some evidence in acne, limited

  • Retinoids are generally avoided in pregnancy. Ask your clinician before using this if you are pregnant, breastfeeding or trying to conceive.
  • Can increase sun sensitivity. Use sunscreen daily.
  • Can cause dryness, peeling or stinging, especially when combined with other actives.

Glycolic acid

The most common alpha hydroxy acid (AHA). It loosens dead skin cells on the surface. The FDA advises sun protection while using AHA products and for a week after. A 2020 Cochrane review found only low-certainty evidence for AHAs in acne.

Some evidence in acne, limited

  • Can increase sun sensitivity. Use sunscreen daily.
  • Can cause dryness, peeling or stinging, especially when combined with other actives.

Frequently asked questions

Can I use glycolic acid in the morning and retinol at night?

Some people with resilient skin do, but a morning AHA increases sun sensitivity right when you are going outside. Alternating nights, with daily sunscreen, is the gentler option.

Can I use a glycolic acid cleanser with retinol?

A rinse-off cleanser is much less irritating than a leave-on toner or serum. Many people can use one, but stop if your skin stings or peels.

Why does Differin say to avoid glycolic acid?

The Differin (adapalene) prescribing information states that products containing alpha hydroxy or glycolic acids should be avoided, because of the risk of added irritation.
