| Popis: | Introduction: Skin aging is the result of many cellular dysfunctions over time particularly the fibroblasts and the keratinocytes. These dysfunctions could be decelerated by the preventive effects of some skin treatments such as Intradermal injections. NCTF 135HA has a polycomponent formulation designed to improve the efficacy of non-cross linked hyaluronic acid (as a micro-filler) on fibroblasts function. Although NCTF 135HA has been used by aesthetic practitioners since 20 years, we have analyzed all in vitro, ex vivo and in vivo studies during past 10 years in order to summarized its anti-aging effect. Methods: In these series of studies, the known effects of HA have been evaluated with this boosted formula. Collagen I synthesis, antiglycation effect and contractile forces developed by fibroblasts were studied. Fibroblasts and keratinocytes proliferations were evaluated in monolayer cells culture. The filling effect thanks to NCTF 135HA injection was ex vivo performed by fringe projection and the protective effect of NCTF 135HA against solar irradiation was performed ex vivo to study proliferation rate, elastin and collagen expression. Two clinical trials were performed on women to evaluate the anti-aging effect of NCTF 135HA injection. Hydration, firmness, radiance, wrinkles size, pore size, thickness and density of the dermis were analyzed. Results: Collagen I, anti-AGE products, cell proliferation and contractile forces were significantly increased with NCTF 135HA in culture medium. Ex vivo studies showed that NCTF 135HA increased, cells proliferation rate, elastin and collagen production. In addition, the filling effect of the NCTF 135HA is significantly superior to placebo. The first clinical trial shows that NCTF 135HA injection significantly increased tonicity, hydration and radiance of the skin and significantly decreased wrinkle score. The second clinical trial demonstrated that NCTF 135HA injection significantly increased dermis density and thickness, skin homogeneity and skin radiance and significantly decreased pore size and wrinkle depth and volume. Conclusion: In vitro, ex vivo and in vivo studies showed that this minimally invasive technique could be used in order to improve the skin quality which could have a visual effect on preventing the aging signs. |
