hi i had some mild acne and i used benzoyl peroxide for about 4 days all over the face. and it ruined my skin. I have developed coarse, rough, wrinkly, skin and there are also areas where there are small dots on my face like mini craters. I dont know how to describe it but I had perfectly normal healthy looking skin before and now it seems to have ruined. it has been a month now since i quite benzoyl peroxide and i have used vaseline, aloe vera gel and moistrizers, but my skin has not become normal. what should i do
