Is benzac (benzoyl peroxide) 5 % good for blackheads ?

Fair: Most use retinoid products and cleaning skin pores with various mechanical and chemical agents. Blackheads are accumulation of skin oil in ducts leading to the skin which collect dirt. Keeping the skin exfoliated often helps. See a dermatologist for proper skin care and script for a time-release retin a (tretinoin) type product.

Yes: While benzoyl peroxide products do help blackheads, retinoids are probably better. There is even one preparation where benzoyl peroxide is combined with a retinoid. This is known as epiduo.If you have medical insurance or can afford to see a doctor i would ask for this product since it works very well.
