Ultra-low fluence 532 nm picosecond laser treatment for acne scars: OCT-observed epidermal vacuole-like changes–a case report

BackgroundTreating atrophic acne scars in Asian skin (Fitzpatrick types III–V) is challenging due to the elevated risk of post-inflammatory hyperpigmentation (PIH). While picosecond lasers with fractional handpiece treatment are effective, the optimal balance between fluence, passes, clinical outcom...
