The peptide N-Acetyl-Tyr-Arg-Hexadecylester (NATAH), found in Part I to stimulate the production of elastic fibers in vitro, was next tested in vivo for its capacity to improve skin elasticity parameters, using various biophysical and imaging techniques. Significant differences in facial ptosis and extensibility were observed in the 56-day, vehicle-controlled clinical study described here.

Melanin-reducing agents are considered safer alternatives to melanocytotoxic compounds. Thus, the present work examines the effects of 3-O-ethyl ascorbic acid on enhancing skin tone by reducing melanin through the inhibition of tyrosinase-related proteins. Described studies include tyrosinase and TRP-2 inhibition, in vitro and ex vivo melanin inhibition, clinical whitening, DNA protection and collagen synthesis.

Ultraviolet and infrared exposure are sources of premature skin aging, characterized by solar elastosis and extracellular matrix degradation. Polygonum aviculare extract is a cathepsin G inhibitor, and is shown here to oppose photoaging and infra’aging by improving skin firmness and elasticity, in turn reducing the appearance of wrinkles.

A placebo-controlled study was conducted to determine if the appearance of wrinkles on facial skin could be improved by a combination of three cosmetic ingredients: dimethylaminoethanol, retinol and mineral salts. Both clinical assessment and video analysis of cutaneous replicas showed a significant improvement of the wrinkle appearance.

To provide consumers an anti-aging benefit, finished products and ingredients must ameliorate both firmness and lines and wrinkles. The loss of firmness, attributed primarily to the loss of underlying dermal support, is both a sign of skin aging and a cause of most lines and wrinkles. Thus, improving this underlying matrix to enhance skin’s appearance should be a key feature of anti-aging product performance.

Coffea species have been widely evaluated for effects including oxidative stress protection and immunomodulation. The present study therefore evaluates the cosmetic activity of an extract obtained from cultured Coffea bengalensis stem cells. Results showed the extract imparted hydration activity in the keratinocytes, stimulated collagen synthesis in the fibroblasts and enhanced adipocyte differentiation starting from mesenchymal precursor cells.

Skin discoloration and excessive pigmentation due to increased melanin production is associated with skin inflammation and aging. Therefore, an extract rich in acetylated hydroxystilbenes from Rheum rhaponticum was combined with panthenyl triacetate to test in the melanogenesis pathway. The complex strongly reduced melanogenesis and melanin accumulation in human skin explants, decreased melanin content in pigmented spots, increased skin brightness and enhanced skin radiance on the face of human volunteers in a double-blind clinical study.

Most antiaging products claim to act on the dermis; however, the epidermis, a key element of cutaneous aging, is often forgotten. In the present study, researchers selected an acetylated tetrapeptide for its effect on epidermis cohesion, triggered by activity on syndecan-1 and collagen XVII; these effects are confirmed in vivo.

The current work aimed to formulate a stable w/o emulsion containing grapefruit extract by entrapping the extract in the inner aqueous phase. The final formula was found to have skin-whitening, moisturizing, cleansing and antiwrinkle effects, among others.
