I had nodular acne three years ago. After treatment with Accutane and a follow up treatment with Retin-A, my acne is now under control. However, under my skin there are what I believe to be sebaceous bumps.
My acne started like this: bumps under my skin, some reached the surface (I had minor surgery to remove that) and those that didn't reach to the outer layer of the skin but are now underneath. It seems as if my body hasn't been able to absorb them. They're like hard, large-sized lumps. There's nothing on the surface of the skin, but when I touch, I can feel them right there.
