Efficacy of Stromal Vascular Fraction on Acne Scar Correction

Autologous stromal vascular fraction (SVF) isolated from adipose tissue was injected intradermally into one side of the face to evaluate its efficacy in treating atrophic acne scars. SVF was freshly prepared on the same day of injection using enzymatic digestion and centrifugation.

Normal saline (NS) was injected intradermally into the contralateral side of the face and served as a placebo comparator to SVF in this split-face study on atrophic acne scars.
