Been having this allergy on my face for over 5 months now. I think it started when I started using face masks. Had visited a dermatologist and she said it was acne and had prescribed me with acretin, zithrova and acm depiwhite cream for the spots to be used after the first two is used. I did as told and there was a slight reduction to it but new acne keeps coming back. Is there a solution for this and is this acne itself ?
