Tretinoin + Benzoyl Peroxide

Can you use Tretinoin with Benzoyl Peroxide?

Yes, with timing

Yes, with timing. Don't apply regular tretinoin and benzoyl peroxide at the same time unless the product is made for it.

Why

Martin et al. (1998) showed that benzoyl peroxide breaks down conventional tretinoin when the two are mixed, especially in light. Newer formulations solve this: microsphere tretinoin and an encapsulated tretinoin plus benzoyl peroxide cream are designed to be used together.

How to use them together

  1. Common approach: benzoyl peroxide in the morning, tretinoin at night.
  2. Or use a prescription combination your dermatologist chooses.
  3. Moisturize and wear sunscreen daily.

Who should be careful

Tretinoin is prescription-only. Ask your prescriber how to combine it. Avoid in pregnancy unless your doctor approves.

About the ingredients

Tretinoin: Prescription retinoic acid (Retin-A and others), used for acne and photoaging. The strongest common topical retinoid; dryness and irritation are common early on.

Benzoyl Peroxide: An antibacterial acne treatment that kills C. acnes. It is an oxidizer, can bleach fabric, and can dry the skin.
