Description

Repair eye cream with blue light resisting effect and preparation method thereof

Technical Field

The invention relates to the technical field of skin care products, in particular to a repair eye cream with an anti-blue-light effect and a preparation method thereof.

Background

The blue light is high-energy visible light with the wavelength of 400-500nm, the wavelength of the high-energy visible light is close to ultraviolet, the wavelength of the high-energy visible light is the shortest, 90% of the blue light which is contacted by people in daily life is from a natural light source, 10% of the blue light is from an artificial light source, the blue light intensity of electronic equipment can reach 80% of the sunlight, and obviously, the blue light is exposed to the blue light every day whether indoors or outdoors.

Blue light penetrates deeper into the skin than ultraviolet light, and can penetrate through the epidermis layer and the dermis layer and reach subcutaneous tissues, so that the blue light has the capacity of damaging all skin layers, and the mechanism of the blue light mainly comprises the following mechanisms: damage DNA and induce oxidative stress; weakening the epidermal barrier; damage to carbonylated proteins and lipids; inducing hyperpigmentation; damage to the extracellular matrix thereby accelerating aging; some studies have shown that overexposure to blue light results in protein aggregation in skin cells, exacerbating free radical production, causing cell damage and delaying repair.

Skin care products related to blue light resistance rarely appear on the market at present, and the blue light resistance mode of the existing skin care products mainly improves the physiological barrier of the horny layer by reducing the content of free radicals of the skin, and the problem that the skin is damaged due to the blue light cannot be solved in principle.

The present invention uses lutein, which is a carotenoid, as a raw material, has excellent antioxidant activity and can filter high-energy blue light harmful to cells. The absorption spectrum characteristic band is between 400-500nm, and the absorption spectrum characteristic band just falls into a blue light region, and has a certain effect on blocking blue light. Meanwhile, the lutein can also effectively delay the degradation of skin elastin and collagen, so as to achieve the purpose of increasing skin elasticity.

The yeast lysate from the yeast fermentation is used as a raw material because severe UV or blue light irradiation causes irreparable cells in the skin, resulting in DNA double strand breaks. Micronucleus number is a measure of irreparable DNA damage. Under blue light pressure, a certain content of the secondary fission yeast fermentation product lysate can reduce the micronucleus formation rate. A biotechnically obtained split yeast fermentation lysate comprising metabolites, cytoplasmic components, cell wall components and polysaccharide complexes. Research shows that the lysate of the yeast fermentation product of the second split can stimulate a DNA moistening repair mechanism after ultraviolet or blue light irradiation, prevent the formation of double-strand breaks (micronuclei), effectively protect skin, keep the skin active, reduce the risk of chronic photodamage and resist the immunosuppression effect induced by ultraviolet or blue light.

Further, the present invention uses niacinamide and tocopheryl acetate.

Repairing damaged stratum corneum lipid barrier and improving skin resistance. Also has effects of deep water locking and moisturizing. The tocopherol acetate vitamin E has strong reducibility and can be used as an antioxidant. Can be used as antioxidant in vivo, and can eliminate free radicals in vivo and reduce the damage of ultraviolet rays to human body.

Furthermore, the cocoa seed extract, which is rich in molecular peptides, saccharides and polyphenols, can maintain the content of opsin photoreceptors under the pressure of blue light, reduce the content of active oxygen, promote the generation of more type I collagen and fibrillar protein-1, and remarkably improve the shape and length of the elastin fiber under UVB and blue light. Meanwhile, the content of Syndecano-4 can be obviously increased, which is very important for repairing the epidermis. It also reduces visible wrinkles and makes the skin surface smoother.

The glucosyl hesperidin in the raw materials has bioflavonoid with high solubility and stability, promotes penetrant, stimulates blood flow and blood circulation of skin, gives warm skin feel to the skin, effectively increases absorption and local metabolism of effective components, and relieves black eye circles, eye edema and tiredness.

The invention uses the centella extract in the raw materials, can effectively promote the tissue repair after skin injury, and particularly has important effect on promoting the anabolism of collagen. Fullerene has strong oxidation resistance, and has skin whitening and wrinkle resisting effects.

The acetyl tetrapeptide-5 in the raw material is used, so that microcirculation can be improved, liquid excretion can be promoted, water is inhibited from leaking into tissues from blood vessels, glycosylation is prevented, edema type eye bags can be effectively solved, and black eye circles can be improved; palmitoyl pentapeptide-4 can stimulate the synthesis of collagen and sucrose amino group hyaluronic acid, has long-acting anti-wrinkle and anti-aging effects, improves true wrinkles and black eye circles, can effectively improve aged sagging type eye bags, and improves black eye circles; acetyl tetrapeptide-5 has the effect of botulinum toxin, promotes the atrophy of hypertrophic eye muscles and effectively improves the muscular pouch. The synergistic effect of multiple active peptides can effectively and comprehensively improve under-eye puffiness and black eye circles.

The allantoin in the raw materials used in the invention has the effects of moistening skin and repairing skin injury, can promote cell growth and accelerate wound healing, has the physiological effect of softening a keratin layer, has good effect on repairing skin sunburn, and also has good moisture retention property.

A qualified patch material is selected, samples prepared in example 1, example 2 and example 3 are placed in a patch tester, 10 holes are placed in each example, the amount of the samples is 0.2g, and no substance is placed in a control hole to serve as a blank. The sample and blank control were applied to the curved side of the forearm of the subject and gently pressed with the palm of the hand to apply evenly to the skin for 24 hours. Removing the patch applicator, keeping the interval for 30min, and observing skin reaction after the indentation disappears. The skin reaction was observed once more 24h and 48h after patch test, respectively.

And (3) judging standard:

and (3) classifying and judging according to the cosmetic contact dermatitis diagnosis standard and treatment principle: the non-reaction of the tested part is (0), the skin has reddish spots (1), the skin has erythema, infiltration or papule (2), the skin has edematous erythema and papule (3), and the skin has obvious redness, swelling, pimple or bulla (4).

In 30 cases, the number of people with grade 2 adverse reactions on skin is more than 2, or any 1 case with grade 3 or more than 3 adverse reactions on skin, and the tested substance is judged to have adverse reactions on human body.
