Hello, Following are some methods by which you can treat acne scars: 1. Fractional CO2 Laser 2. Fractional Er: YAg LAser 3. Fractional Nonablative ND YAg 4. Fractional Erbium Glass Laser 5. Dermaroller 6. Microneedle RF 7. Subscision 8. TCA CROSS Dermatologist will decide which one is the best one for you, as it depends upon scar type, depth of scars and also how much downtime you can afford to have(how much holiday you can take after the procedure because it takes different periods of time for healing to take place with each procedure). During the procedure, however, use of sunscreen is absolute must. Sunscreen, preferably 30-50 SPF should be used every 3 hours to get optimal protection. In your case use a non comedogenic sunscreen like Neutrogena Ultrasheer Dry touch Sunscreen.
