I’ve got a mixture of rolling and box scars due to cystic and pustule acne a year ago. The acne scars are mild to moderate mainly on the cheeks and hairline. The best option would be fractional lasers. But, why do i see some clinics suggest 4-6 sessions. Spaced out for about 4-6 weeks and it requires downtime for 5 days as well. And some says 1-3 sessions is enough? I would go for the second option if the results is good?
