hi dear, your skin is oily in fact. the dryness u r getting now is due to
isotane. i wont suggest u
dermaroller now, as when isotane is on we dont do any procedures. it may cause
hyperpigmentation. finish the course of isotane , wait for a month and then go for dermaroller. for now u must use some sunscreen. for ur oily skin suncote sunscreen ll be best. thank u
