Hi)) My doctor offers me nano fat injections to improve acne scars. The procedure is similar to PRP but she also adds nano fat to plasma. According to my doc, it is the best option as it supposedly totally renews old skin and thus scar tissue improves. Should I go for it? Any contradictions or side effects? Additional info: I had Fraxel, TCA peel, Infini RF with PRP. Skin type III. Sarcoidosis in lungs. Thanks a lot in advance!
