Effaclar Duo Dual Action Acne Face Wash
A daily acne cleanser built around 4% benzoyl peroxide, with niacinamide, sodium hyaluronate and a small amount of glycolic and capryloyl salicylic acid alongside it.
Apply a dime-size amount to damp skin, massage gently avoiding the eye area, then rinse well. Keep it away from eyes, lips, mouth, hair and dyed fabrics.
- 4% benzoyl peroxide in a rinse-off format, so it acts on acne-causing bacteria without a leave-on step
- Niacinamide and sodium hyaluronate in the base to offset some dryness
- Large 200 ml size at a low price per ml
- Benzoyl peroxide can dry or irritate skin, especially when layered with other actives
- Can bleach towels, pillowcases, hair and dyed fabrics
