Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a composition for improving skin elasticity and delaying aging and a preparation method thereof.

Background

The aging of the skin is divided into endogenous aging and exogenous aging, wherein the endogenous aging refers to natural aging of the skin along with the increase of the age, the most main reason of the exogenous aging is photoaging caused by sunlight, for example, ultraviolet irradiation causes a large amount of free radicals in the skin to be generated, the collagen and DNA structure health can be damaged, the collagen and DNA structure health can be embrittled and even broken, the collagen regeneration is prevented, and the skin cannot obtain enough nutrition supply, so that the vitality is reduced. Aging of the skin is manifested by wrinkles, decreased elasticity, skin laxity, roughness, pale yellow or grayish yellow skin discoloration, telangiectasia, formation of pigmented spots, and the like. Along with the pursuit of modern people on skin youth, the functions of tightening, resisting wrinkles and delaying aging gradually become the important functional requirements of current cosmetics, so that the development of the products has very practical significance and good market application prospect.

Ceramide is a lipid naturally and purely existing in the skin, forms a waterproof barrier on the surface of the skin, and can help the skin to lock water, promote the self-repair of the skin barrier and regulate and control skin cells. The secretion of ceramides in the skin decreases with age, which in turn causes skin dryness, wrinkles and some skin inflammations. In terms of its chemical structure, ceramide is composed of a sphingosine long-chain base (constituting about 50% of the structure) and a fatty acid. Different sphingosine bases and fatty acids combine to form different ceramides. Currently, 9 naturally occurring ceramides are found. In addition to these, there are also plant ceramides, ceramides and synthetic ceramides. Can help the stratum corneum to thicken, promote the tolerance of the whole skin, prevent the invasion of external harmful substances, avoid the occurrence of sensitivity and have the function of repairing the red blood streak.

Caprylic/capric triglyceride is high-purity grease formed by esterifying caprylic/capric acid and glycerol, is excellent moisturizing grease, has good spreadability, enables the skin to have a smooth but not greasy feeling, is easy to be absorbed by the skin, and plays a good role in the uniform and fine cosmetics to enable the skin to be smooth and glossy.

Macrogala, i.e., algin, is a polysaccharide substance extracted from the kelp belonging to the phylum Phaeophyta, the order Laminariales, the genus Macrogalum, the family Macrogalaceae.

The lysate of the yeast fermentation product of the bifidus is obtained by culturing, inactivating and decomposing bifidobacterium to obtain metabolites, cytoplasmic fragments, cell wall components and polysaccharide complexes. Has strong immunosuppressive activity, can promote DNA repair, can effectively protect skin from being damaged by ultraviolet rays, is used for skin care, sun protection and after-sun care products of emulsion, water-based and hydroalcoholic systems, and helps to prevent photoaging of epidermis and dermis. In addition, the yeast extract can also generate small molecules which comprise vitamin B group, minerals, amino acids and the like and are beneficial to skin care, is a high-quality yeast essence, can strengthen the metabolism of stratum corneum, can capture free radicals, inhibit lipid peroxidation, has the functions of whitening and resisting aging, is rich in nutrient substances and has the function of nourishing skin.

Polypeptide, which stimulates epidermal cell differentiation and neogenesis, strongly promotes epidermal repair and healing, and inhibits scar formation. It has effects of supplying skin nutrients to the dermis of the skin, stimulating the activity of fibroblasts, promoting the healing and functional regeneration of skin wounds, and enhancing the structure of extracellular matrix. Enhancing skin resistance to environmental insults, irritants, ultraviolet radiation, inflammatory substances and pollutants, increasing skin elasticity, promoting scar tissue regression, delaying skin aging, and strengthening skin tone.

The biological carbohydrate gum-1 is a linear biological polysaccharide, has strong water binding capacity, has good water absorption effect even in a low-humidity environment, and forms a breathable carbohydrate film on the surface layer of skin. Preventing skin moisture from evaporating again, and has instant and long-acting moisturizing effect.

Kangaroo flower extract, Kangaroo flower is a plant unique to southwestern western Australia, and is named because it is shaped like a curved paw of Kangaroo. In vitro and in vivo tests prove that the kangaroo paw extract has multiple effects of stimulating the secretion of tenascin-X, promoting the generation of collagen precursor I, promoting the synthesis of elastin, activating fibroblasts and improving roughness.
