Effect of mesotherapy with nanochip in the treatment of facial rejuvenation.

: To observe the clinical effect of mesotherapy with nanochip for facial rejuvenation.: 24 volunteers with aging skin were treated with a polycomponent formulation - NCTF® BOOST 135 HA for 5 times (once weekly for 3 times and successively biweekly for 2 times). Photographs were taken by VISIA at baseline, and after 1, 4, 10 weeks, while global scores for photoaging (GSP), improvement scores, volunteers' satisfaction, parameters describing the properties of the skin, and adverse effects were assessed during each follow-up period.: Total 20 volunteers completed the treatment. Evaluation of the whole face showed that GSP, skin texture (ophthalmic wrinkles, dermal thickness, and intensity of collagen fibers of skin), and skin brightness (Lab value) significantly improved at 4 weeks compared to baseline, while the difference between 4 and 10 weeks was not statistically significant. No evident improvement was observed in pigmented spots, telangiectasia, skin tightening, trans-epidermal water loss (TEWL), and skin hydration. Slight erythema, pain was the most common side effect.: Mesotherapy with nanochip can improve skin texture and brightness, but the effect is not permanent. It is recommended that the treatment be used as a complementary method for patients with facial rejuvenation needs.
