Description
Technical Field
The invention relates to the technical field of skin care products, and particularly relates to an antioxidant moisturizing composition and application thereof in anti-aging moisturizing essence.
Background
With the rapidly increasing air pollution and the increasing living pressure of modern society, the balance of free radicals on the surface layers of the skin of more and more people is destroyed due to the bad intervention of the external environment, and the organism generates excessive free radicals, thereby leading the skin to have the aging characteristics of wrinkle, dry keratinization, lackluster, excessive color spot deposition and the like.
The adolescence is the period of handsome and beautiful appearance in the whole life of a human, and at the moment, the skin is soft, smooth, glossy, full, elastic, white, transparent and red. By age 25, metabolism begins to slow, moisture and subcutaneous fat decrease, elastic fibers become thicker, and skin becomes wrinkled and lustrous to disappear. After age 40, the body hormone balance is disturbed, keratin is reduced, elastic fibers are broken, the skin is loose, rough and wrinkles are increased, and the skin gradually enters the aging stage. The aging of the skin is the prominent expression of the aging of the whole body, wherein the aging of the skin on the face is particularly obvious, the number of fibroblasts in the human body is gradually reduced, the secreted collagen and the elastic fibrin are gradually reduced and broken by oxidation, the supporting effect on the skin is eliminated, the inhomogeneous collapse is caused, the dermis layer begins to be thinned, the elasticity of the skin is deteriorated, and wrinkles begin to be gradually generated.
The 'water shortage' is one of the most important patents of the sensitive skin, the worse and worse the skin becomes and the skin is aged, the water replenishing and moisturizing are not only patents of the sensitive skin, various skins are lack of water due to factors such as environment, age, nutrition, health and the like, when the moisture content of the horny layer of the human skin is lower than 10%, the skin loses the fineness and the elasticity, becomes rough and dry, various skin abnormalities occur, if the skin is not corrected for a long time, the skin is easy to age, the skin becomes sensitive due to long spots, and the water replenishing is needed to be paid attention to the anti-aging process.
With the progress of society, the development of economy and the continuous improvement of the living standard of people, the requirements of people on beauty and skin care cosmetics are higher and higher, and the beauty and skin care cosmetics are developed in the direction of naturalization, nutrition and curative effect.
