at my teenage.now they have disappeared leaving my skin extremely oily and hypersensisitive.doc suggested me to use faceclin gel(clindamycin and nicotinamide) and cetaphil face
dry. Then apply a good hypoallergenic moisturizer over the area.Also exfoliate the skin once or twice weekly with a mild exfoliating scrub.
If still the symptoms persist then pls get it evaluated from a dermatologist.
I hope that helps. Please do keep me posted on how you are doing or if you have any additional doubts.Warm regards.
