Hello,
This scarring is due to post inflammatory hyperpigmentation after the cuts. Without treatment, this usually takes about 6 months to resolve and for the skin color to go back to its normal color. 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.
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.
Hi,
The dark spot is called "post-inflammatory hyperpigmentation". It's common that you have it after an injury to the skin. To get rid of it, you can apply Hydroquinone cream ONLY under prescription of your dermatologist.
The raised scar is called "keloid". It is also common after an injury. To get rid of it you can apply Dermatix, Mederma, or Hiruscar.
Good luck!
