The existing cosmetics generally have the moisturizing effect, but after a lot of cosmetics are applied to the face, the instant moisturizing effect can be achieved, but the phenomenon of tight interference easily occurs after a while, or part of the cosmetics feel sticky and thick after being applied to the face and are not easy to absorb, because the moisturizing component of the formula is single, and the moisturizing effect is not ideal due to the addition of a large amount of macromolecular substances and other factors, and the use experience is poor. The polysaccharide peptide adopted by the invention is characterized in that hydrolyzed collagen with the molecular weight of about 1000 is grafted on fine euglena polysaccharide molecules, and permeates into a skin basal layer through the hydrolyzed collagen with the small molecular weight, so that the generation of collagen is promoted, and the aging is fundamentally slowed down. In addition, the applicant finds that when the polysaccharide peptide and the water-based elastin are compounded in a specific ratio, the elasticity of the skin can be increased, the use feeling can be increased, the lubricating hand feeling is improved, and the skin is not thick, heavy and sticky; in addition, the skin care product has self-subacidity, so that the skin cuticle can be softened, the absorption of other molecules by the skin is promoted, and the thick and sticky feeling of non-absorption is reduced. In addition, the palmitoyl hexapeptide-12 added into the system has a nerve conduction inhibiting substance, can avoid over contraction of muscles to prevent fine wrinkles and slow down the force of muscle contraction, so that the muscles are in a relaxed state, the generation of dynamic wrinkles is reduced, the collagen elasticity of the polysaccharide peptide can be reorganized, the activity of hydrolyzed elastin is increased, and the support is provided for the skin under the combined action of the collagen elasticity and the dynamic wrinkles. Meanwhile, sodium hyaluronate is added into the system, can permeate into the epidermis layer of the skin to promote the proliferation and differentiation of epidermal cells, and generates a synergistic effect with the added antioxidant, so that free radicals are effectively eliminated, dry and rough skin is repaired, and the skin elasticity is increased.
