The dark spots indicate postinflamatory hyperpigmentation
.this has a tendency to aggravate on sun exposure so use of sunscreen is must
following treatment is indicated:
, tertinoin combination cream at night
sunscreen like suncote gel in the day, repeat every three hours. avoid sunexposure as much possible
you can go for tca spot peels or glycolic or lactic peels.
saliac ac face wash or spongysal face wash for oily skin
