Formula design principle of the present invention is as follows:

Lily candidum extract contains a large amount of organic acids, flavonoids, glycosides and other substances, which can proliferate fibroblasts, promote the activity of cathepsin, have anti-aging effects, and promote "luciferase activity" function, has anti-inflammatory effect. The contained aspartic acid has anti-oxidation effect, Ophiopogon japonicus polysaccharide is a natural moisturizer, and veratramine has a strong inhibitory effect on tyrosinase, which can whiten and remove freckles. Therefore, Lily candidum extract is an excellent whitening, moisturizing and anti-aging active substance.

Yeast fermentation product extract not only contains skin beneficial ingredients such as monosaccharides, polysaccharides, minerals, and vitamins produced by yeast fermentation, but also contains amino acids, nucleotides, and other active ingredients after degradation of proteins and nucleic acids in yeast cells. ingredients. After fermentation or degradation, the small molecular weight substances formed have stronger penetration and are easier to penetrate into the deep layer of the skin to be absorbed. Among them, free amino acids are an important part of the skin's natural moisturizing factor, and amino acids and polypeptides have a good effect on inhibiting the formation of tyrosinase melanin. Rich vitamins and polysaccharides can resist oxidation, anti-inflammatory and anti-aging. Minerals stimulate the body's cell production, while organic acids gently exfoliate; thus leaving the skin smooth and supple.

Paeonol is an active ingredient extracted from the dry root bark of the ranunculaceae plant peony. At a concentration without killing cells, paeonol can effectively inhibit the tyrosinase activity of melanoma cells and human epidermal melanocytes, thereby effectively inhibiting melanin synthesis. On the other hand, paeonol can inhibit the generation of O ^{2 -} free radicals in cells, slow down the fibrosis of protein cells, cause skin loss of elasticity and produce wrinkles; slow down the peroxidation reaction of fat cells, resulting in dull skin and the formation of pigmentation . Therefore, paeonol has the effect of whitening the skin and reducing and fading the deposited pigment in the skin. In addition, paeonol also has a good anti-inflammatory effect.

Dipotassium glycyrrhizinate can activate corticosteroids, indirectly enhance the effect of corticosteroids, effectively prevent skin sensitivity and inflammation when stimulated, and has anti-inflammatory and sedative effects on inflammation. When used in combination with paeonol, the anti-inflammatory effect can be synergistic , for anti-allergic and repair skin tissue.

Amylopectin has a high degree of branching, its structure is conducive to hydrogen bonding with water molecules, and it is easy to disperse into a viscous colloidal solution. Aging, and easy to adhere to the surface of the skin, the three-dimensional space structure can carry and control the slow release of active substances such as paeonol and dipotassium glycyrrhizinate, so as to achieve long-term repair of the skin.

Phenoxyethanol is a substance with a strong killing effect on Pseudomonas aeruginosa, and p-hydroxyacetophenone is also an excellent preservative. It is mixed with Lily candidum extract and yeast fermentation product extract respectively. It can effectively inhibit the growth of microorganisms and maintain the activity of the extract.

Bis(hydroxymethyl) imidazolidinyl urea is a kind of preservative, which plays a bactericidal and antibacterial effect by releasing formaldehyde, especially has an antifungal effect. It can greatly improve the antiseptic effect when shared with methylparaben and propylparaben. performance.

Xanthan gum, one of the biological gums with superior performance, integrates the functions of thickening, water-locking, suspending and emulsifying. It has good miscibility with other thickeners, and compounding can improve the viscosity of the product and lock in moisture at the same time.

Niacinamide is non-acidic and non-irritating. It is a highly absorbable water-soluble substance that can reduce the movement of melanosomes from melanocytes to keratinocytes, block the transmission of melanin, and reduce the amount of melanin transferred to the surface cells. , to achieve whitening effect. Moreover, niacinamide can increase the level of free fatty acids and ceramides in the skin, promote keratin synthesis, and help the skin retain water. The most important thing is that nicotinamide can inhibit the aging of sugar and indirect anti-aging. If the sugar intake is excessive and cannot be completely metabolized by the body, the sugar will attach to the protein in the dermis, causing the collagen to lose its elasticity and turn brown, and the elastic fibers to also lose their elasticity. Broken due to glycation. Niacinamide stimulates collagen production and slows down the sugar aging process.

Compared with the prior art, the beneficial effects of the present invention are:

A whitening and moisturizing composition provided by the present invention comprises the following components: Lilium candidum extract components, yeast fermentation product extract components; nicotinamide, paeonol components. Lily candidum extract contains a large amount of organic acids, flavonoids, glycosides and other substances, and is an excellent active substance for whitening, moisturizing and anti-aging. Yeast fermentation product extract contains skin beneficial ingredients such as monosaccharides, polysaccharides, minerals, and vitamins produced by yeast fermentation, as well as active ingredients such as amino acids, nucleotides, and other active ingredients that are degraded from proteins and nucleic acids in yeast cells. The penetration is stronger, and it is easier to enter the deep layer of the skin to be absorbed, effectively improving the moisturizing, whitening and anti-aging effects. Paeonol and nicotinamide are also whitening, moisturizing and anti-aging active substances with good skin adsorption. The present invention combines the extract components of Lily candidum, the extract components of yeast fermentation products, nicotinamide and paeonol, which can promote the absorption of active substances by the skin, thereby achieving a synergistic effect on deep moisturizing, whitening and anti-aging. effect.
