What benzoyl peroxide does for your skin

Benzoyl Peroxide · BPO · BP

Clarity

Yes, as long as you keep them in separate parts of the day rather than in the same layer: benzoyl peroxide in the morning, retinol or retinal at night, so both stay comfortable on the skin. The same split works for vitamin C. Benzoyl peroxide also bleaches fabric, so use white towels and pillowcases with it, and put moisturiser on top since it can leave skin dry.

Benzoyl peroxide is the classic pick for inflamed, stubborn-looking breakouts, and it is a fast-moving active rather than a slow, gradual one. In cosmetic terms it purifies and refines. The smart move is to go lower on strength than you'd think.

What Benzoyl Peroxide is

Benzoyl peroxide suits angrier, inflamed-looking breakouts, where BHA tends to suit calmer congestion. Go with 2.5%: the stronger 5 to 10% versions are considerably more drying and more likely to leave skin red and tight. Two heads-ups worth knowing before you start.

What is Benzoyl Peroxide good for?

inflamed, angry-looking breakouts
stubborn spots that other actives don't shift
oily, blemish-prone skin
a clearer, calmer-looking finish over time

How do you use Benzoyl Peroxide?

2.5% is where to start: far less drying than 5 to 10%.
It bleaches fabric, so mind your towels and pillowcases.
If you also use retinol or vitamin C, put benzoyl peroxide on in the morning and save those for night.
Ease in rather than starting daily.

Baselit puts benzoyl peroxide in the morning slot for exactly this reason, and the retinoid in the evening.

What does it pair with?

Keep it apart from retinol, retinal, vitamin C, AHAs and BHA in the same layer, since it cancels some of them out on contact. The classic split is benzoyl peroxide in the morning, retinol at night. Baselit handles this split for you.

Frequently asked questions

What does benzoyl peroxide do for skin?

In cosmetic terms, benzoyl peroxide purifies and refines. It's the classic pick for inflamed, stubborn-looking breakouts, and it is a fast-moving active rather than a slow, gradual one.

What strength of benzoyl peroxide is best?

2.5% is where most routines start. The 5 to 10% strengths are considerably more drying and more likely to leave skin red and tight, so there is little reason to reach for them first.

Can I use benzoyl peroxide with retinol?

Not in the same layer, since the two don't sit well together on the skin at the same time. Put benzoyl peroxide on in the morning and save retinol for night. Baselit's routine builder splits them for you automatically.

Does benzoyl peroxide bleach fabric?

Yes. It can bleach towels, pillowcases and clothing, so be careful around fabrics and let it dry before it touches them. White bedding is the safe choice.

Is benzoyl peroxide better than salicylic acid?

They suit different looks. Benzoyl peroxide tends to suit angrier, inflamed breakouts, while salicylic acid (BHA) suits non-inflamed bumps and congestion. Some routines use both on different days.
