Ive had acne for years and i got a severe case on my back.. i took accutane and i got rid of it.. finally 
but the problem is that every pimple left a scar... white or skin colored raised a little and thet vary in size they are wrinkley and soft.. now ive done a research and i know its called "anetoderma" or "follicular macular atrophy"
i tried to take a better pic than that.. but it was on my back.. it looks worse in real life btw
Does anyone know any information about it and how to treat it?
