Stop picking at your pimples
Inflammation left over after the acne has cleared up is what contributes to scarring, according to Angela Lamb, MD, a dermatologist with Mount Sinai Hospital in New York City. If you want to prevent scarring, keep your hands off the area: no rubbing or scratching. Picking at your skin increases inflammation and can damage skin further, which makes scars appear worse and last longer. It can also push bacteria deeper into the skin, causing more serious collagen damage.
Treat acne at the first sign of trouble
The best way to avoid acne scars is to treat your acne issues from the start. Dr. Lamb recommends aggressively treating your acne before it gets out of control. If your skin takes a sudden turn for the worst, see a dermatologist for a professional opinion and treatment. And experiment with these various home remedies for acne.
