이 치료에 대해

Subcision treats fixed atrophic depressed scars (tethered acne scars) by surgically severing sub-epidermal fibrotic attachments. Special needle physically breaks fibrous connections causing depression. Subsequent fibroblast activation rebuilds collagen, lifting scars. Particularly effective for deep scars resistant to fractional laser/microneedling.

작용 기전

18-20G special needle inserted beneath scar tissue (dermis-subcutaneous) to deliberately sever fibrous septae causing depression. Creates local trauma triggering fibroblast activation. Rapid collagen remodeling lifts scar; elevation improves depression. Multiple sessions provide cumulative benefit.

적응증

여드름여드름 흉터·반흔

기대 효과

40-60% crater improvement after 3-6 sessions. Tethered scars show dramatic improvement with multiple treatments. Complete elimination difficult but marked improvement in visibility. Fractional laser+subcision combination more effective.
