Ingredients / Benzoyl peroxide
Benzoyl peroxide
A powerful anti-acne ingredient that kills the bacteria behind breakouts. Effective but can be drying and bleaches fabrics.
How to use it
Spot-treat or use as a short-contact wash. Don’t layer it with a retinoid in the same session — it deactivates many of them.
Avoid combining with
Benzoyl peroxide + Retinoid (Vitamin A)
Benzoyl peroxide oxidizes and deactivates most retinoids, cancelling their benefit.
→ Use benzoyl peroxide in the AM and the retinoid at night, or on alternate days.
Benzoyl peroxide + Vitamin C (L-ascorbic acid)
Benzoyl peroxide can oxidize vitamin C, reducing its effectiveness.
→ Apply at different times of day.
