Hi, you have acne which is quiet common at your age.
It occurs due to hormonal
changes that your body is undergoing at this age .due to formation of androgens
, they stimulate the oil glands to make more of oil which collects in the duct and clogs the ores and thus black heads and white heads are formed .
they further progress to acne. so follow these things-
-use a salisylic facewash twice a day
and white head extraction regularly.
-dont squeeze or pick the pimples, doing this may lead to pigmentation and scars
which takes long time to go.
-aviod junk food
-for active acne apply clindamycin2% gel in morning and combined with adapalene
-for scars use retino A at night on forehead
use if for a month or so if it doesnt help contact your doctor to start oral azithromycin
