Types of acne scars Depressed scars include ice-pick, boxcar and rolling scars. Raised scars include hypertrophic scars and keloids. Flat brown or red marks after acne are not true scars, although they may remain for months.
Assessment The best treatment depends on scar depth, shape, skin tone, active acne and tendency to form keloids. Active acne should usually be controlled before beginning major scar procedures.
Treatment options Treatment may include microneedling, fractional laser, radiofrequency microneedling, chemical reconstruction of deep scars, subcision, fillers, punch techniques or injections for raised scars. A combination is often more effective than one procedure alone.
Expectations and safety Improvement is gradual and complete removal is rarely possible. Multiple sessions may be required. Darker skin tones need careful settings and sun protection to reduce the risk of post-inflammatory pigmentation. Procedures should be performed by trained medical professionals after discussion of downtime, risks and expected improvement.
