Application of plant extracts in anti ageing cosmetics

Apr 25, 2022

Recently, with the high-speed development of cosmetics and the green concepts widely applied in various industries, people have also put forward the requirements for pure natural, nontoxic side effects and other aspects of antiaging cosmetics, which has created a good basis and premise for the application of natural plant extracts in antiaging cosmetics. the addition of natural plant extracts should be used in cosmetics to achieve the anti-aging function of cosmetics and become a development trend in the cosmetic industry.

Natural plant extracts mainly include α- Hydroxy acids β- Hydroxy acids, plant flavonoids, papain sulfhydryl enzymes, and so on, which can effectively improve the senescent state of the skin and achieve the goal of delaying skin aging.

01. Grape seed extract 

Grape seed extracts mainly have proanthocyanidins, grape seed oil, resveratrol, vitamins, tannins, etc., which have cosmetic and health care effects. Procyanidin has strong antioxidant potential and its antioxidant effect is 50 times that of VE and 20 times that of VC, grape seed procyanidin extract has 85% bioavailability in the human body. Procyanidins can inhibit the generation of peroxides caused by UV irradiation of the skin; they May also inhibit the Maillard reaction and inhibit the formation of lipofuscin and senile plaques; Also inhibits tyrosinase activity, which reduces the o-phenylenediquinone structure of melanin to a phenolic type structure, rendering the pigment faded. So proanthocyanidins have the effects of improving skin inflammation, preventing melanization, whitening skin, and anti-aging.

resveratrol

The grape seed oil also has a high mass fraction of VE, which can reach 360 μ g/g。 While VE is able to speed up the clearance of damaged and senescent cells, protect regenerating and newborn cells, and retain water to the point of retarding skin aging. Grapeseed oil has shown some antioxidant effects and delayed senescence.

02. Rhodiola Rosea Extract 

Rhodiola Rosea Extract

The main chemical components of Rhodiola Rosea Extract are salidroside and flavonoids. Salidroside not only significantly enhances the anti ionizing radiation ability of the skin, but also protects against various rays( α、β、γ) Radiation damage to lipids and cell membranes, improves cardiopulmonary function, anti-fatigue, protects the body's immune system, and exerts anti-aging effects. Flavonoids have super potent superoxide dismutase (SOD) activity and free radical scavenging effects, which repair damaged skin, anti-lipid oxidation, and anti-aging.

In the extraction process of active ingredients of salidroside and its cosmetic efficacy study, the efficacy of the extracts was examined by comparison with a positive substance control, Rhodiola Rosea Extract was demonstrated to possess in vitro antioxidant and tyrosinase inhibitory capacities, May serve as an additive to delay aging and whitening cosmetics.

03. Rose Extract 

Rose Extract

It has been found that rose contains a large number of phenolic, flavonoid as well as polysaccharide compounds which have good efficacy in scavenging free radicals and retarding senescence. In addition to this, a large amount of vitamin C that rosettes contain also has strong antioxidant properties.

Rose extract is rich in nutrients, so it can be applied to a cream, exerting the efficacy of delaying aging while locking the skin's original moisture and nutrition. Rose in addition can be used to extract essential oils, which have been lauded as " liquid gold " because of their extremely low yield and great efficacy.

Modern cosmetics are diverse and more varied in functionality, and among them, those containing natural plant extracts with anti-aging functions are one of the most intensively marketed.
