Scar therapy on the legs
I would begin with topical Plato's Scar Serum and Melarase PM, followed by fractional laser to exfoliate the skin followed by light chemical peels. Best, Dr. Karamanoukian
How to get rid of cat scratch marks and dark marks on my leg?
Thank you for your question and I am sorry to hear of your scarring issues. The first step would be prevention of receiving fresh scratches from your cat. The second step would be to moisturize your legs and arms well and use a sunblock to prevent pigmentation changes from the suns UV radiation. A lightening cream such as hydroquinone can then be used to lighten the scars' appearance but If after a few months you see little change, chemical peels can be performed. I am attaching a link below with additional useful information.
