Application :

It is used for treating acne.
It commonly causes initial dryness and sometimes irritation, although the skin develops tolerance after a week or so. A small percentage of people are much more sensitive to it and liable to suffer burning, itching, peeling and possibly swelling. It is sensible to apply the lowest concentration and build up as appropriate.  Once tolerance is achieved, increasing the quantity or concentration a second time and gaining tolerance at a higher level usually gives better subsequent acne clearance.

Other common uses for benzoyl peroxide include dying hair, and as an active ingredient in teeth whitening systems.It is also used in the preparation of flour, and can be used as an initiator and catalyst for polyester thermoset resins
