Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to evaluate the efficacy and safety of intradermal injection of autologous stromal vascular fraction (SVF) in the treatment of atrophic acne scars. SVF is a heterogeneous cell population derived from adipose tissue, containing various regenerative and immunomodulatory cells, including mesenchymal stem cells, endothelial progenitor cells, and pericytes.

In this prospective, randomized, split-face clinical trial, participants with atrophic acne scars will receive SVF injections on one side of the face and normal saline (NS) injections on the contralateral side as a control. Clinical efficacy will be assessed through blinded scar counts, digital imaging, and histological evaluations including epidermal and dermal regenerative markers. The study is designed to investigate whether SVF provides superior clinical improvement compared to placebo.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

SVF-treated side

Intradermal injection of autologous stromal vascular fraction (SVF) on one side of the face.

Group Type EXPERIMENTAL

stromal vascular fraction (SVF)

Intervention Type BIOLOGICAL

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.

Saline-treated side

Intradermal injection of normal saline (NS) on the contralateral side of the face.

Group Type PLACEBO_COMPARATOR

Normal Saline (NS)

Intervention Type OTHER

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.
