 Hi, I am Dr. Sachit Abraham, consultant dermatologist at Manipal Hospital in Bangalore. Yeah, one of the most important things is to treat acne at the right time and tell the patient not to keep squeezing and meddling with the pimples. Usually scars happen because people have a habit of constantly putting their finger and squeezing the acne. And then it leaves the scar and scars are much more difficult to treat. But we can improve scars on the face by certain treatments like chemical peeling, microdermabrasion, derma roller, fractional lasers. These are treatments which needs repetitive treatments. So it's always prevention is better than cure. Better not to get a scar. Once you get a scar it is, it is, it can be treated but it's much more difficult to treat a scar.
