Benzoyl peroxide (BPO) is one of the most-used ingredients for breakout-prone skin, and it's been around for decades. Here's how I tell clients to use it.
What it does
BPO helps keep pores clear and is a long-standing ingredient for blemish-prone skin. It's often paired with an exfoliant like salicylic acid. Our Benzoyl Peroxide 10% is designed to go on the whole face, not just on spots.
✨ Ask Rae: New to BPO? Start every other night and switch to white pillowcases.
How to use it
- Apply a thin layer to clean, dry skin.
- If you're new to it, start every other day and build up.
- Some dryness or flaking at first is common. Follow with a light moisturizer like the Balancing Emulsion.
- Wear Morning Moisture SPF 30 during the day.
Watch your towels
BPO can bleach fabric. Use white towels and pillowcases, and let it dry fully before you pull on a shirt.
