Avoid mixing retinol and AHAs/BHAs as it can cause irritation. Vitamin C should not be combined with niacinamide because it can reduce effectiveness.

  3. What happens if benzoyl peroxide is used with retinol? Benzoyl peroxide and retinol can deactivate each other when used together, and this combination often leads to increased skin dryness.
