Background: Improvements in skin erythema and elasticity have been observed with topical application of platelet-rich plasma after fractional laser (FXD) treatment. Injections of nanofat via small needles into the dermis improves tissue thickness, discoloration and wrinkle depth.
Objectives: The aim of this study was to evaluate improvements in skin following a nonablative FXD treatment combined with the application of a novel topical nanofat biocrème, called neo-U.
Methods: Fifty patients were treated with a nonablative FXD followed by application of a topical nanofat biocrème. Harvested fat was processed into nanofat, which was compounded with a transdermal liposomal delivery vector to produce a topical biocrème. In 2 patients, postauricular skin punch biopsies were performed before and after treatment and examined for histologic changes. Photographs of a historical group treated with only the FXD were compared with photographs of patients treated with a combination of topical nanofat biocrème and FXD. Skin types were evaluated for improvements in nasolabial folds, wrinkles, and skin texture.
Results: Findings from postauricular skin biopsies show the skin exposed to FXD with nanofat biocrème had more elastin fibers and a slight increase in the thickness of the epidermis. Patients treated with FXD plus nanofat biocrème had a statistically significant improvement in the degree of wrinkles, nasolabial fold depth, and texture compared with historical controls.
Conclusions: Transdermal delivery of nanofat topical biocrème applied after FXD treatment can serve as a delivery system to improve fine lines, nasolabial fold depth, and overall texture of the tissue to a greater degree than laser resurfacing alone.
