1. The efficacy and safety of combined microneedle fractional radiofrequency and sublative fractional radiofrequency for acne scars in Asian skin
   J Cosmet Dermatol (2016) — DOI: 10.1111/jocd.12195 — PMID: 26578429

   Combining microneedle and sublative fractional radiofrequency significantly improved atrophic acne scars in Asian patients, with about 70% achieving at least 50% scar reduction and minimal complications.

2. Fractional Q-Switched 1064 nm Laser for Treatment of Atrophic Scars in Asian Skin
   Medicina (Kaunas) (2022) — DOI: 10.3390/medicina58091190 — PMID: 36143867

   All 29 Asian patients treated with a fractionated Q-switched 1064-nm Nd:YAG laser over three sessions showed significant atrophic acne-scar improvement with no prolonged erythema or pigmentary alteration.

3. Treatment of Facial Acne Scarring With Fractional Carbon Dioxide Laser in Asians: a Retrospective Analysis of Efficacy and Complications
   Dermatol Surg (2017) — DOI: 10.1097/DSS.0000000000001219 — PMID: 28746258

   A retrospective review of 107 Asian patients treated with fractional CO2 laser for acne scars documented efficacy alongside a 15% adverse-event rate, chiefly hyperpigmentation, underscoring pigment-safety planning in darker skin.
