I have had teenage acne for the past three years? Starting four when I start school again. Anyways, I went to the doctor for my acne (I use to get small pimples here and there near the bridge of my nose and under the eyes a little). She gave me EpiDuo, which contains Benzoyl peroxide. It bleached my skin so I stopped using it completely. Now I have an uneven skin tone that hasn't improved or gone away at all for a few years. The same goes for my red marks. My acne has worsened, to huge pimples that sometimes merge together or are in clusters, on the area mention earlier, forehead acne that has a few pimples and raised bumps, as well as some near my ears. I'm currently using a sulfuric acid cleanser in the morning and night, pills contains Retin A (?) and a night cream called Ziana, and a moisturizing sunscreen all reccomeded by my dermatologist. I really want to know what those red marks are and if my uneven skin tone can be darkened somehow.
