Thank you for your question and photographs.Wound healing after skin excisions can take up to 2-3 months, but unfortunately, the indentation may be a permanent scar. With that being said, effective treatments for atrophic scarring are aimed at triggering the skin to produce more collagen, the body's natural filler. Any of the modalities that injure the skin with subsequent collagen formation such as fractionated laser, dermaroller, resurfacing lasers, deep peels, etc., may help your condition. Fillers are also a good option, specifically Bellafill®, a permanent filler. Bellafil® is FDA approved in treating acne scars. The right modality for you depends on your skin type, expectations, patience, downtime, and cost. I highly recommend you consult with a board certified dermatologist or plastic surgeon to have your skin evaluated and to discuss appropriate treatment options that best suit your needs. Take care and good luck.
