Acne scars originate from the long-lasting inflammation caused by acne. Acne scars occur most frequently in those with moderate acne to severe acne. It remains unknown why some people develop acne scars when others don’t.
Many treatment options are available to diminish the acne scars’ appearance. Depending on the type (depressed or raised) and severity of scarring, improvement can be seen in 4 to 6 weeks.
Treatment for Depressed Acne Scars:

• Resurfacing: Laser therapy, chemical peeling, dermabrasion, microdermabrsion
• Fillers
• Skin tightening
• Collagen-induction therapy, aka needling
• Electrodesiccation
Treatment for Raised Acne Scars:
