Located in the outermost layers, the primary structures and components responsible for the skin’s barrier function are susceptible to environmental variables, dermatological conditions, and the aging process. The ensuing alterations to structure, composition, and organizational attributes of the epidermal barrier can impact its integrity and functionality. The aim of this study was to assess the effect of a novel complex composed of a ceramide, energizing peptide, and Camu Camu extract (SUPCERAT<sup>TM</sup> complex) on specific markers of epidermal barrier integrity, as well as epidermal and dermal function. All the experiments were conducted on fresh human abdominal skin explants. Intradermal production of hyaluronic acid, epidermal claudin-1, and ceramide synthase 3 expressions, as well as epidermal lipids content were assessed using specific fluorescent stainings on ex vivo skin after the application of the complex or placebo. Additionally, dermal elastase and collagenase activities were assessed using in tubo enzymatic assays. Lastly, the effect of a cosmetic cream containing SUPCERAT<sup>TM</sup> complex was assessed using subjective Global Aesthetic Improvement Scale (GAIS) in a small cohort of patients after 60 days of use. The application of the SUPCERAT<sup>TM</sup> complex on ex vivo skin led to significant increase in dermal hyaluronic acid content and epidermal activity of claudin-1, ceramide synthase 3 and epidermal ceramide content. Furthermore, in tubo enzymatic assays demonstrated inhibition of both dermal elastase and collagenase activities. In addition, the patient-reported results indicated significant improvements in skin quality and appearance. .展开更多

P. undulate flesh was homogenized and digested using papain under optimal conditions, then subjected to Sephadex G-25 chromatography to isolate the LMWP. Administration of LMWP significantly reversed D-galactose-induced oxidative stress by increasing the activities of glutathione peroxidase (GPx) and catalase (CAT), and by decreasing the level of malondialdehyde (MDA). This process was accompanied by increased collagen synthesis. The LMWP prevented photoaging and promoted dermis recovery and remission of elastic fiber hyperplasia. Furthermore, treatment with the LMWP helped to regenerate elastic fibers and the collagen network, increased superoxide dismutase (SOD) in the serum and significantly decreased MDA. Thermal scald-induced inflammation and edema were also relieved by the LWMP, while wound healing in skin was promoted. These results suggest that the LMWP from P. undulate could serve as a new antiaging substance in cosmetics.展开更多

[Method] The anti-aging efficacy of the aqueous extract of C.anoderrna luciclum was evaluated by sensory evaluation, safety evaluation, instrumental measurements, etc. [ Result] The results of sensory evaluation showed that after continuous application of the test materials for 12 weeks, the skin dryness, elasticity, surface sheen, fine wrinkles and smoothness were well improved, and the improvement rates were 9l. 17%, 91.17% , 94.12% , 11.76% and 91.18% , respectively. The measurement results by specialized instrument showed that the skin hydration on the target site increased continuously with the prolonging of the using time. Significant differences existed between each time point after using the products and the time before using. There was no signiScant difference existed in elasticity index 112 and R5 compared with before using. [Result] Clinical data showed that the active ingredients in aqueous extract of Ganoderma lucidum had a certain effect on the delaying of skin aging.展开更多
