Can you mix Benzoyl Peroxide and Retinyl Retinoate?

ClashThese clash.

Benzoyl peroxide can break most retinoids down, and together they often over-irritate, so you can lose the retinoid and gain redness.

Do this: Use them at different times: the retinoid at night, benzoyl peroxide in the morning.

How to introduce Benzoyl Peroxide and Retinyl Retinoate

Patch test each one first: a coin-sized amount on your inner forearm for two or three days, watching for redness or stinging.
Split them across the day: Benzoyl Peroxide in the morning, Retinyl Retinoate at night, rather than layered in the same routine.
Ease the benzoyl peroxide in slowly: start at two nights a week for the first fortnight, then build up only as your skin stays comfortable.
If skin turns tight, flaky, red or starts to sting, drop back a step and let your barrier recover for a few days before pushing on again.

Two strong actives at once is a lot to ask of your skin. Going slow is exactly what keeps this pairing working instead of backfiring.

For your skin type If your skin is sensitive or reactive, take this pair slowly: Benzoyl Peroxide is the higher-irritation ingredient here, and using actives close together magnifies that.
