Hi, I'm female, 19 years old. I have some questions, hope that you will help. Last year, when I found my face have lots of acne spots, I went to drug store and bought Differin to treat them. I used it for 4-5 months and lead to really sensitive, red, dry skin, especially red. I visited 2 dermatologists, the first seemed to make it worse, but the second dermatologist said that: I used medications in wrong way, so it lead to dry skin and lots of acnes. So she gave me this prescription: nicebiotamin, curacne and acneal( for spots on face). It took 3 months to see the changes. My acnes have gone a lot, redness has reduced. But now I still have dry, rough skin while oily on T-zone. I wonder if it's because of dead skin on my face. I exfoliate once a week with oatmeal. Can you give me some advices. Thank you!
