Herpes scar continue to mature and improve over a year. They almost always go fade away however more severe outbreaks can leave permanent irregularities or discoloration. You can continue treating your scar with various methods. Topical options include silicone-based strips or gels. Most importantly, keep it out of the sun. Overtime, your scar should continue to improve on its own. For accelerated healing or if it stops improving, microneedling with or without PRP, fractionated laser, and radiofrequency make microscopic holes in the scar to stimulate your body to remodel and fill in the scar with new collagen. I especially like a combination of microneedling with PRP for texture and collagen building, and PIXEL fractionated laser or RF to resurface and build even more collagen for a smooth even look that blends into your skin. Not everyone is a candidate for all the treatment options however as certain skin types can get worse from certain treatments. For the safest treatment plan, it is important to visit an expert for an in-person examination. Hope this helps! Johnson C. Lee, MD Board-Certified Plastic Surgeon IG: @drjohnsonlee
