I went off antibiotics a month and a half ago and did alright for a while. Three days ago, a cyst started forming above an old hyperpigmented scar. It has continued to grow, and it's beet red. I've been using Retin-A and Avar-E at night, along with hydrocortisone or Desonate for the redness. Nothing is helping. I went back on 100 milligrams Minocycline on Tuesday and have increased to 200 today. I think the zit is less painful today than it was yesterday, but the redness around it is ridiculous. It's also still a pea-sized knot protruding from my skin. Thoughts on how to shrink it, avoid a chemical burn, and prevent hyperpigmentation? My skin is ridiculously sensitive. I'll end up with a red mark no matter what I do, but I really don't want to go in for a cortisone shot... And I want to stop the antibiotics again ASAP. I took this picture this morning. It's even redder tonight, but I don't want to take another picture. I haven't picked it or squeezed it at all. I've washed it gently. This is just how much my fair skin sucks.
