8 months ago I developed a huge cystic pimple on my nose and since I have a red raised acne scar on my nose. My derm prescribed tretinoin and benzoyl peroxide - they reduced the overall amount of acne on my face, but did not help the scar. Next he prescribed a steroid cream (fluticasone) for the scar, however it hasn't helped either. My derm doesn't specialize in cosmetics so he suggested looking elsewhere now. How can I get this fixed? Laser? Microneedle? Fraxel? 26 male
