Description

Anti-aging composition and preparation method and application thereof
Technical Field
The invention discloses a composition, in particular to an anti-aging composition, a preparation method and application thereof, belonging to the technical field of cosmetics.
Background
The skin is the outermost tissue of the human body and plays a role in protecting the human body from external injury and resisting various external mechanical, chemical, physical and biological stimuli. Human skin aging is classified into endogenous aging, which is an aging process occurring with the increase of age under the influence of genetic factors, and exogenous aging, which is aging caused by the influence of the environment on the skin. The main factor of environmental impact is the damage of free radicals, which are abundant in active oxygen free radicals 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 cellular tissues of the human body through strong oxidative reactions. Therefore, signal transduction of human cells is disturbed, apoptosis is accelerated, skin aging is accelerated, and a series of chronic skin health problems such as dry skin, laxity, desquamation, melanin increase, and even skin spots are caused, which afflict many consumers.
Scavengers of free radicals, known as antioxidants, achieve antioxidant action by inhibiting or terminating the oxygen radical chain reaction. In recent years, with the increasing demands of people on cosmetics, such as safety, high efficiency, no stimulation and the like, the natural antioxidant of plant source is increasingly emphasized due to the characteristics of wide source, safety, effectiveness, natural, no toxicity and the like. Natural antioxidants are of various types and generally include superoxide dismutase, catalase, glutathione, carnosine, vitamin C, vitamin E, plant polyphenols, flavonoids, carotenoids, etc.
At present, many anti-aging and anti-wrinkle products on the market supplement collagen and elastin in the skin, or use a single antioxidant to reduce the generation of free radicals to achieve the anti-aging purpose. However, most of substances contained in the composition are macromolecules which are difficult to absorb by skin, and in addition, antioxidants are often irritant to a certain extent, and the risk of easy inactivation exists, so that the antioxidant and anti-aging effects are not ideal.
In summary, the antioxidant and anti-aging products which can effectively remove free radicals and 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.
