Known Interactions
Benzoyl Peroxide oxidizes and deactivates Retinol on contact. These must never be in the same formulation.
Benzoyl Peroxide oxidizes L-Ascorbic Acid, rendering both ingredients inactive. These must never be combined.
Benzoyl Peroxide oxidizes Retinyl Palmitate, deactivating both. All retinoid forms are incompatible with BPO.
Benzoyl Peroxide oxidizes Hydroquinone on contact, forming a dark brown/orange stain on skin. These must never be combined.
Benzoyl Peroxide oxidizes and deactivates Tretinoin on contact. Never combine. Use BPO in the morning and Tretinoin at night if both are needed.
Benzoyl Peroxide can oxidize Vitamin E (Tocopherol), reducing antioxidant efficacy. The BPO may also be partially neutralized.
