Cosmate®RESV,Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi. Alexin is from the Greek, meaning to ward off or to protect. Resveratrol may also have alexin-like activity for humans. Epidemiological, in vitro and animal studies suggest that a high resveretrol intake is associated with a reduced incidence of cardiovascular disease, and a reduced risk for cancer.

Resveratrol is a polyphenolic compound widely found in plants. In 1940, Japanese first discovered resveratrol in roots of plant veratrum album. In the 1970s, resveratrol was first discovered in grape skins. Resveratrol exists in plants in trans and cis free forms; both forms have antioxidant biological activity. The trans isomer has a higher biological activity than cis. Resveratrol is not only found in grape skin, but also in other plants such as polygonum cuspidatum, peanuts, and mulberry. Resveratrol is a natural antioxidant and whitening agent for skin care.
Resveratrol is the main raw material in pharmaceutical, chemical, health care, and cosmetics industries. In cosmetic applications, resveratrol is characterized by capturing free radicals, anti-oxidation, and anti-ultraviolet radiation. It is a natural antioxidant. Resveratrol can also effectively promote vasodilation. Moreover, Resveratrol has anti-inflammatory, anti-bactericidal and moisturizing effect. It can eliminate skin acne, herpes, wrinkles, etc. Therefore, Resveratrol can be used in night cream and moisturizing cosmetics.

Benefits:

*Anti-oxidation

Resveratrol protects cells from oxidative stress; it is an antioxidant that activates the synthesis of other compounds. Resveratrol also regulates inflammatory response and even helps distribute the cosmetic sunscreen, so that it helps prevent UV damage to skin. A study in 2008 showed that topical application of resveratrol to skin can prevent UV-induced damage. Structural similarity allows resveratrol to replace estrogen in postmenopausal women. So resveratrol can reduce collagen loss and delay skin aging.

*Whitening

Resveratrol can also act as a skin lightening agent that inhibits tyrosinase activity. It also fights photo-aging by inhibiting synthesis of melanin. It makes skin whiter and less pigmented. It is confirmed in animal models that topical application of resveratrol inhibits melanin production, and reduces skin pigmentation after UV irradiation.

*Anti-inflammation

A 2002 study showed that resveratrol inhibits the growth of bacteria and fungi that cause skin infections, such as Staphylococcus aureus, lactococcus, and Trichophyton. Moreover, resveratrol can reduce the ability of skin cells to produce hydrogen peroxide. As the level of inflammation decreases, the cumulative damage in the cells also decreases. Even acne can be alleviated by use of resveratrol, because it has antibacterial property that controls growth of sebaceous gland cells.

Resveratrol itself is sensitive to UV light. It is recommended for use with other sunscreens, or use at night to maintain its effectiveness. Night cream containing 1% resveratrol, 1% vitamin E and 0.5% baicalin can increase synthesis of collagen and other proteins. Also the formulation reduces fine lines and wrinkles, increases skin elasticity and dermal thickness.
Combined with green tea extract, resveratrol can reduce facial redness in about 6 weeks.
Resveratrol has synergistic effect with vitamin C, vitamin E and retinoic acid.
Resveratrol can reduce skin irritation caused by alpha hydroxy acid when used in combination with alpha hydroxy acid.
Mixing with butyl resorcinol (a derivative of resorcinol) has a synergistic whitening effect and can significantly reduce melanin synthesis.
Resveratrol and UV-filter can also be combined into a cosmetic formulation. The formulation has following advantages: 1) prevents UV-induced resveratrol decomposition; 2) enhances skin permeability, and improves bioavailability of effective active ingredients in cosmetics; 3) avoids recrystallization of resveratrol and 4) enhances stability of cosmetic formulation

Description:
Resveratrol (also known as SRT-501) is a phytoalexin derived from grapes and other food products with antioxidant and potential chemopreventive activities. Resveratrol induces phase II drug-metabolizing enzymes (anti-initiation activity), mediates anti-inflammatory effects and inhibits cyclooxygenase and hydroperoxidase functions (anti-promotion activity), and induces promyelocytic leukemia cell differentiation (anti-progression activity), thereby exhibiting activities in three major steps of carcinogenesis. This agent may inhibit TNF-induced activation of NF-kappaB in a dose-and time-dependent manner. Resveratrol is a natural compound used in cosmetic material.
