Adapalene vs Benzoyl Peroxide
Which is right for your skin?
Adapalene normalizes how pores shed skin to prevent breakouts; benzoyl peroxide kills the bacteria behind active ones. A classic combo: adapalene at night, benzoyl peroxide in the morning.
A gentler prescription retinoid that focuses on clogged pores and acne. Better tolerated than tretinoin for most skin.
Kills the bacteria that cause inflammatory acne. The first thing to reach for when you have red, painful pimples.
Can you use Adapalene and Benzoyl Peroxide together?
We have no documented layering conflict between Adapalene and Benzoyl Peroxide. Introduce one at a time and patch-test.
You want anti-acne. A gentler prescription retinoid that focuses on clogged pores and acne. Better tolerated than tretinoin for most skin. (Prescription only.)
