Hello,
For scarring there are are many treatment options available which include various skin creams like hydroquinone, azelaic acid, corticosteroids and tretinoin cream. Topical treatments with acids and chemical peels can be effective but can take a while for the skin to totally revert to its normal color. Microdermabrasion can also be done, but this might require several sessions. Skin resurfacing using lasers is also an option. But if it is an indented scar then collagen fillers and laser treatment are effective.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
