Abstract

Background

Fat grafting has been extensively applied as natural filler and has been very promising in restoring volume loss. Lipografting has also been credited to reduce age-related skin changes due to the regenerative potential of adipose derived stem cells. Cell-mediated therapies in plastic surgery are rapidly evolving with growing applications. Nanofat, a bio-regenerative liquid suspension rich in stromal vascular fraction cells without viable adipocytes, has been described as an efficient cutaneous anti-aging therapy. We have published in 2013 a review entitled “stem cell facelift: between reality and fiction.” Available clinical evidence at that time did not substantiate marketing and promotional claims of "stem cell facelift". The same year, the report about nanofat was published demonstrating striking clinical outcome. The current literature search is aimed at reviewing any evidence that has emerged since then regarding clinical efficacy of this modality.

Methods

A thorough PICO tool-based comprehensive literature search of PubMed database for “the efficacy of nanofat cell-mediated anti-aging therapy” was conducted with a time frame from 2013 till present.

Results

Despite apparent increasing popularity of stem cell rejuvenation, well-controlled clinical studies about this modality are surprisingly very scarce. Only seven papers published after 2013 were identified and were included in this review

Conclusion

Though considered to be a safe procedure, and despite documented histologic improvement and striking clinical outcome in some reports, available evidence can hardly support clinical improvement of skin quality. Before cell-mediated aesthetic rejuvenation applications can be routinely undertaken, more robust evidence with well-defined primary outcome end points and objective outcome measures is required.
