What is the best treatment for rolling acne scars?

When rolling scars are tethered by fibrous bands under the skin, subcision treats the mechanism itself: it releases the bands that pull the surface down. In a study of 40 patients who completed follow-up, improvement reported by patients and doctors was about 50% at 6 months, and 90% of patients said their appearance had improved. In a comparative study of 20 patients, the reduction in the size and depth of rolling scars was clearly greater with subcision than with 100% TCA CROSS (p<0.001). These numbers support the principle, but they do not mean every rolling scar needs subcision or that 50% is a guaranteed result.

Key numbers

  • ≈50% — Improvement in a 40-patient study
  • 90% — Patients reporting better appearance
  • Significant difference (p<0.001) — Compared with TCA CROSS
  • 5 sessions every 4 weeks — A newer small trial

When does subcision really make sense?

  • When the scar improves as the skin is stretched sideways, or tethering is found on examination, the fibrous component matters.
  • If the scar is shallow and not tethered, resurfacing or microneedling/RF may matter more than releasing under the skin.
  • Deep, narrow ice pick scars are not the classic target for subcision and need a different strategy.
  • Combining with resurfacing, RF or filler depends on what remains after the bands are released, not on stacking procedures in one session.

Key takeaways

  • Tethered rolling scar = treat the fibrous pull before only chasing the surface.
  • Subcision has direct data for rolling scars, but the result varies with depth, number and technique.
  • The scar type matters more than the device name or the price of a session.
