Retinol + Benzoyl Peroxide
Retinol + Benzoyl Peroxide — a pairing of a vitamin A derivative with benzoyl peroxide, an ingredient commonly used to target acne-causing bacteria. The two are sometimes used in blemish routines, but benzoyl peroxide can degrade some forms of retinol and both can be drying, so timing matters.
Key points
- Benzoyl peroxide targets acne-associated bacteria, while retinol supports turnover and helps keep pores clear.
- Benzoyl peroxide can oxidize and reduce the effectiveness of some retinol formulations when applied together.
- Many routines separate them, using one in the morning and the other at night, to avoid this interaction.
- Both can cause dryness and irritation, so gradual use and diligent sun protection are advisable.
Frequently asked
Can benzoyl peroxide be used with retinol?
They can both feature in a blemish routine, but because benzoyl peroxide may degrade some retinols, they are often applied at different times of day.
Should I apply retinol and benzoyl peroxide at the same time?
Many people avoid simultaneous application to prevent potential degradation and combined dryness, instead using one in the morning and the other at night.
