BACKGROUND: Lipofilling has become popular as a treatment to improve aging related skin characteristics (eg, wrinkles, pigmentation spots, pores, or rosacea). Different additives such as platelet-rich plasma (PRP) or stromal vascular fraction (SVF) have been added to lipofilling to increase the therapeutic effect of adipose derived stromal cells (ASCs).
OBJECTIVES: In this study, we hypothesized that mechanical isolated SVF augments the therapeutic effect of PRP supplemented lipofilling to improve facial skin quality.
METHODS: This prospective, double-blinded, placebo-controlled, randomized trial was conducted between 2016 and 2019. In total, 28 female subjects were enrolled with 25 completing the follow-up. All patients received PRP supplemented lipofilling with either mechanical isolated SVF or saline. SVF was isolated by means of the fractionation of adipose tissue (FAT) procedure (tissue-SVF). Results were evaluated by changes in skin elasticity and transepidermal water loss, changes in skin aging related features, ie, superficial spots, wrinkles, skin texture, pores, vascularity, and pigmentation as well as patient satisfaction (FACE-Q), recovery, and number of complications up to 1 year postoperative.
RESULTS: The addition of tSVF to PRP supplemented lipofilling did not improve skin elasticity, transepidermal water loss nor skin aging related features. No improvement in patient satisfaction with overall facial appearance nor facial skin quality was seen when tSVF was added to PRP supplemented lipofilling.
CONCLUSIONS: PRP supplemented lipofilling with tSVF compared to PRP supplemented lipofilling alone does not improve facial skin quality nor patient satisfaction in a healthy population. PRP supplemented lipofilling with tSVF can be considered a safe procedure.
