1. Why am I using DUAC ONCE DAILY GEL?

in acne. Benzoyl peroxide acts to reduce comedones (blackheads and whiteheads). It
is also effective at killing the bacteria, which are involved in acne, and makes the
skin less oily.
DUAC ONCE DAILY GEL is used on the skin to treat acne. It helps to:
reduce the bacteria or germs, which are implicated in acne;
reduce the number of acne spots;
reduce the likelihood of new blackheads and whiteheads from forming; and
make your skin less oily
