Description

Cosmetic matrix, preparation method and application thereof, eye cream and preparation method thereof

Technical Field

The invention relates to the technical field of cosmetics, and particularly relates to a cosmetic matrix, a preparation method and application thereof, and eye cream and a preparation method thereof.

Background

The eyes are the parts of the face which are exposed to the age at the earliest, and the eyes which face to the face are vigorous, so that the whole face of the user is more youthful. The sub-ocular region is very sensitive and subject to irritation. It is nearly ten times thinner than skin in other parts of the body, with few sebaceous glands, and is therefore more prone to dryness and irritation. Dark circles are mostly inherited, but also due to the following factors: stress, unhealthy diet, vitamin and mineral deficiencies, smoking, alcohol consumption, uv damage, evidence of blood vessels and capillaries under the skin, irritation, and natural melanin. All or just some of these factors, coupled with the ever thinner dry skin and the effects of earth's gravity, pull on the skin and make the dark circles appear larger, dull and fatiguing.

The main causes of dark circles are poor blood circulation and blood leakage in delicate tissues around the eyes, and poor sleep also aggravates dark circles, which are the second major concern of consumers following wrinkles in european countries and several countries around the world. Therefore, a cosmetic for effectively removing black eyes is also important. The existing eye cosmetics have poor black eye circle removing effect, the melanin reducing effect on skin around eyes after use is limited, and meanwhile, the general eye cosmetics cannot well play a role in improving the skin brightness around eyes.

As can be seen from tables 1 to 10, the melanin values of examples 5 to 8 are decreased, and the skin color L and ITA are both significantly increased, compared with comparative example 1, and thus, the eye cream using the base of the present invention has the effects of significantly relieving dark circles and lightening the skin color around the eyes. The eye cream using the base of example 7 has the best black eye removing effect and brightness improving effect.

Comparative example 2 compared to example 5, the substrate did not contain tea extract to encapsulate boswellia serrata extract; comparative example 3 compared to example 6, the matrix contained no date seeds; comparative example 4 compared to example 7, the matrix contained no soy protein, hydrolyzed rice protein and superoxide dismutase mixture; comparative example 5 compared with example 8, the matrix does not contain the polygonum cuspidatum root extract, and the reduction degree of the melanin value before and after use, the increase degree of the skin color L x value and the ITA ° are reduced in different degrees, so that the active ingredients of the cosmetic matrix have a synergistic effect, and no significant effect can be obtained by reducing one of the ingredients.

In comparison with example 5, the ratio of the components of the base material was different from that of the present invention, and the degree of decrease in melanin value before and after use, the degree of increase in skin color L x and ITA ° were also decreased, and thus it was found that the cosmetic base material of the present invention could achieve significant effects of relieving dark circles and lightening skin color by the mutual matching of the components in a specific ratio.

In conclusion, the cosmetic matrix disclosed by the invention is prepared by reasonably matching a tea extract coated boswellia serrata extract, an orange peel extract, date seed, acetyl tetrapeptide-5, wild soybean protein, a hydrolyzed rice protein and superoxide dismutase mixture, a polygonum cuspidatum root extract and ascorbyl tetraisopalmitate, and optimizing the formula amount of the matrix, so that the effects of the components have a mutual synergistic effect and a better effect is achieved, the components are fully coordinated and complemented, the antioxidation effect is obvious, melanin can be remarkably reduced, the skin color is brightened, and the black eye circle can be effectively relieved after the matrix is applied.

While particular embodiments of the present invention have been illustrated and described, it would be obvious that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
