Description

Cosmetic composition for nursing eye skin and preparation method thereof

Technical Field

The invention relates to a cosmetic composition, in particular to a cosmetic composition for nursing eye skin, and also relates to a preparation method of the cosmetic composition, belonging to the technical field of skin care products.

Background

The thickness of the eye skin is 1/3-1/5, which is about the thickness of the cheek skin, and is the most tender and fragile skin of the human body, and one of the most frequently moving and heavily burdened parts, therefore, the eye skin is very easily stimulated and influenced by the external environment and the pressure in the body. Generally, after 25 years old, the skin around the eyes begins to go down the slope, and black eyes, wrinkles, pouches and other problems appear.

Dark circles are annular, uniformly pigmented areas located in the bilateral infraorbital areas and generally appear dark or dark-tea. A black eye ring is mainly caused by staying up all night, unstable emotion, eye fatigue, aging, insufficient oxygen supply of red blood cells of eye skin, excessive accumulation of carbon dioxide and metabolic waste in vein blood vessels, chronic hypoxia, dark blood and venous blood retention in vein blood vessels or micro blood vessels. The other is dark brown eye which is mainly caused by eye pigmentation due to insufficient melanin production or metabolism. The older the person, the thinner the subcutaneous fat around the eye becomes, so the more visible the dark circles.

The eye pouch is formed by eye fatigue, aging, poor long-term microcirculation, excessive water and fat accumulation, skin elasticity reduction around the eye socket, eye skin relaxation, and subcutaneous fat moving downwards to the lower eye socket to form a convex pouch. Bags and dark circles under the eyes are often triggered by inflammation. Inflammation is caused by ultraviolet rays, oxidation of free radicals, stress, fatigue, and allergy. The inflammation causes capillary exudation, which accumulates under the eye. In addition, eye skin becomes thinner and less elastic with age, and subcutaneous fat accumulates to protrude from the skin under the eyes to form pouches.

With age, lymphatic and blood circulation becomes slower, and blood backflow is insufficient, resulting in darker skin around the eye and possibly hemoglobin accumulating in the connective tissue, forming dark circles. Over time, the weakened dermal layer gradually loses collagen and elastin supplementation and support, and the skin tissue surrounding the eye relaxes, causing the eyelids to become puffy and the appearance of fish tail lines and wrinkles of the lower eyelid to begin. In addition to age factors, the act of blinking may also exacerbate the deterioration of periocular wrinkles. In addition, the weak epidermis also reduces the thickness of the lipid film, which increases the rate of water loss from the skin around the eyes and makes the skin around the eyes less elastic. Therefore, dark circles, pouches, and eyelid slacks are often accompanied by canthus wrinkles. The formation of eye wrinkles is mainly due to the dry and thin epidermis tissues and the loss of reticular supporting force caused by insufficient supplement of collagen and elastic fibers in the dermis. The skin loses elasticity and does not recover after being squeezed, so that sagging and wrinkles of the skin are formed. If the function of sebaceous glands is reduced, sebum secretion is reduced, sebaceous membranes are not easy to form, water in horny layer is easy to lose, and skin becomes dry, so that fine wrinkles are more easily generated. Secondly, the skin of the eye is affected by the external environment to form free radicals, and the free radicals destroy collagen, elastin and oxidation cells in normal cell membrane tissues to form fine lines and wrinkles.

The international large brands in the current eye products are expensive and can be borne by non-ordinary people, the quality of the products in middle and low-end markets is good, and most of the products have no practical effect on improving eye skin.

To better illustrate the effects of the present invention, comparative examples of experimental protocols of the present invention during development are given below.

Comparative example 1

A cosmetic composition is free of Sambucus nigra flower extract and horse chestnut extract, and other components and contents and preparation method are the same as those of example 4.

Comparative example 2

A cosmetic composition is free of methylsilanol hydroxyproline aspartate and other components and amounts and preparation method are the same as in example 4.

Comparative example 3

A cosmetic composition containing no retinol palmitate, other components and contents and preparation method are the same as those of example 4.

Comparative example 4

A cosmetic composition comprises the following components in percentage by mass based on 100% of the total mass: 1.5% of Sambucus nigra flower extract, 2.5% of horse chestnut extract, 1% of inula flower isodon chrysanthemum extract, and other components and contents and preparation methods are the same as those in example 7.

Experimental data of a cosmetic composition for caring eye skin and a comparative example thereof provided in the present application are given below.

100 volunteers with eye bags, dark circles, fine wrinkles and the like on the skin around eyes of 35-50 years old were selected and randomly divided into 10 groups of 10 persons, and the products of examples 3-8 and comparative examples 1-4 were used respectively in such a way that the face was cleaned every day and used twice a day (each time after getting up in the morning and before sleeping in the evening). The skin elasticity of the eyes was measured with skin elasticity tester MPA580 and the skin melanin value of the eyes of the volunteers with skin melanin and heme tester (mexamettx 18) before and 8 weeks after use, respectively. Meanwhile, each group of testees respectively evaluate the effects of fading black eye circles and bags under the eyes and improving fine lines of the test samples, the average score is calculated by taking 10 as a full score, 7-10 as an obvious effect, 4-7 as a general effect and less than 4 as no obvious effect.

TABLE 1 elasticity and Melanin status of eye skin

TABLE 2 evaluation results of human body

As is apparent from tables 1 and 2, the cosmetic compositions of examples 3 to 8 of the present invention exhibited significantly increased elasticity and significantly decreased melanin in the eye skin, indicating that the cosmetic compositions of the present invention had a significant effect of lightening dark circles, pouches and fine wrinkles.

Comparative example 1 in comparison to example 4, the cosmetic composition contained no elderberry flower extract and horse chestnut extract; comparative example 2 in comparison to example 4, the cosmetic composition contained no methylsilanol hydroxyproline aspartate; comparative example 3 compared with example 4, the cosmetic composition does not contain retinol palmitate, and the degree of improvement of the skin elasticity of the eyes, the degree of reduction of melanin and the results of human body evaluation before and after use are all lower than those of example 4, so that it can be seen that the effective ingredients in the cosmetic composition of the present invention have a synergistic effect, and no significant effect can be obtained by reducing one of the ingredients.

Compared with the example 7, the proportion of the three components of the elderberry flower extract, the horse chestnut extract and the inula flower isosac chrysanthemum extract is different, and the improvement degree of the elasticity of the eye skin before and after use, the reduction degree of melanin and the human body evaluation result are all lower than those of the example 7, so that the plant extract can obtain the remarkable effect of lightening black eyes, pouches and fine lines by the mutual matching of the three components with specific proportions.

The above embodiments are preferred embodiments of the present invention, but the present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents thereof, and all such changes, modifications, substitutions, combinations, and simplifications are intended to be included in the scope of the present invention.
