I'm 21 year old. I've never had pimple on my face until 2 months back when I started having these little bumps which started to grow bigger. I consulted a dermatologist, she told me it might be due to bacterial infection. She proscribed me an antibiotic and a face gel. My acne breakouts reduced and gradually stopped but has left these deep pinkish spots. dermatologist suggested to go for 5 derma roller sessions. Pls I need advices regarding this procedure, if it would work for fresh acne scars.
