I am a 25 year old man and have some blackheads and pimples which suddenly crept up 2 months ago and have been persistent since, then. I had visited 2 dermatologists and one of them prescribed Supatret C Aqueous gel while the other one prescribed sebonac gel 1%. I noticed that on applying these as advised (1hour every night, I broke out terribly and discontinued both of these after a week of use. Could you please advice if, I should reduce the frequency in the beginning before, i begin to use these every night. Also, to add, I have moderately oily skin which both the dermatologists described as sensitive.
