Description

Anti-aging composition and preparation method and application thereof
Technical Field
The application discloses a composition, in particular an anti-aging composition, a preparation method and application thereof, and belongs to the technical field of cosmetics.
Background
The skin is used as the outermost layer of the human body, and plays roles of protecting the human body from external injury and resisting various stimuli such as external machinery, chemistry, physics, biology and the like. Skin aging in humans is classified into endogenous aging, which is affected by genetic factors, which is an aging process that occurs with age, and exogenous aging, which is aging of skin due to environmental influence. The main factor of the influence of the environment is mainly the damage of free radicals, and a large amount of active oxygen free radicals exist in our living environment. The damage of free radicals to human skin is mainly caused by lipid peroxidation, protein peroxidation and DNA damage, which continuously attack and destroy the outer cell tissues of the human body through strong oxidation reactions. Thus, human cell signaling is disturbed, apoptosis is accelerated, skin aging is accelerated, and a series of chronic skin health problems such as xerosis cutis, laxa, desquamation, melanin increase, and even skin spots are caused, which afflict many consumers.
Radical scavengers are known as antioxidants, which achieve an antioxidant effect by inhibiting or terminating the oxygen radical chain reaction. In recent years, with the increase of demands of people on cosmetics, such as safety, high efficiency, no stimulation and the like, plant-derived natural antioxidants are increasingly valued due to the characteristics of wide sources, safety, effectiveness, nature, no toxicity and the like. Natural antioxidants are of a wide variety and generally include superoxide dismutase, catalase, glutathione, carnosine, vitamin C, vitamin E, plant polyphenols, flavonoids, carotenoids, and the like.
Currently, many anti-aging and anti-wrinkle products are available in the market to supplement collagen and elastin in skin, or to use a single antioxidant to reduce the generation of free radicals to achieve the anti-aging purpose. However, most of the substances contained in the anti-aging agent are macromolecules and are difficult to absorb by skin, and in addition, the anti-aging agent is often irritative to a certain extent, and the anti-aging agent is easy to deactivate, so that the anti-oxidation and anti-aging effects are not ideal.
In conclusion, the antioxidant and anti-aging products which can not only effectively remove free radicals but also promote the production of collagen and elastin are developed through the combination of plant extracts at present, and the antioxidant and anti-aging products have wide market application prospects.
