Description

Composition with skin pore improving and long-acting moisturizing effects and application thereof

Technical Field

The invention relates to the technical field of cosmetics, and particularly relates to a composition with skin pore improving and long-acting moisturizing effects and application thereof.

Background

With the increasing of the moving rhythm of modern life, the increase of working pressure, the increase of entertainment modes and the like, the night stay and the irregular life, season change and the influence of male hormone cause the abnormal metabolism rate of cutin, the thick cutin is accumulated around the pore, the pore becomes rough and is easy to be blocked, so that blackheads and white heads are formed, the inside of the pore is gradually enlarged, and the phenomenon is most easily appeared on the forehead, the nasal wings and the cheeks at two sides. With the gradual appearance of loose and big pores and the erosion of the external environment, elastic fibers and collagen in the dermis begin to be loosened and broken, so that the skin tension and elasticity are poor, and the pores losing the surrounding supporting force have oval and big pores. This condition most likely occurs in the cheek area around the statute line, accelerating aging. The pore with the exuberant sebum secretion is a live crater, grease can explode out everywhere, and the blockage caused by the exuberant grease secretion leads the metabolism of the skin to be unsmooth and can not fall off in due period, so that the pore is enlarged. Therefore, skin moisturization is a very critical step in the routine skin care process. The normal water content of the stratum corneum is generally 20% to 30%. When the water content is lower than 10%, the metabolic function of the horny layer is disordered, the skin lacks water and has low moisture-keeping function, other skin problems such as dry, rough, loss of luster, reduction of elasticity and the like are easily caused, and skin barrier dysfunction is caused when the skin lacks water seriously, so that the infection of skin diseases is increased, and skin diseases such as dermatitis, eczema, psoriasis, acne and the like can be induced. The moisture retention and water supplement are well made, so that the natural barrier of the skin can be maintained, the skin is kept smooth and fine, skin diseases are prevented, and people need to retain moisture and supplement water.

At present, cosmetics in the market are various in variety, most of skin care products are essence skin care products aiming at improvement of moisture retention, wrinkle resistance and oxidation resistance, and have the effects of improving pores and long-acting moisture retention and water supplement, so that the skin care matrix with the comprehensive skin care effects of improving pores and long-acting moisture retention has very important significance.

the products of the examples and the comparative examples were applied to the face of volunteers for 21 consecutive days 2 times a day in an amount of 2mg/cm and allowed to dry naturally for 3min, the transepidermal water loss (TEWL) was measured with TEWAMATE210 instrument, and the moisture content of the skin was measured with FACIAL analyzer, the higher the moisture content of the skin, the better the moisturizing effect of the test samples.

After 1 month of continuous use, data analysis was performed by the above test method, and the test results are shown in tables 3 and 4 below.

Table 3 test results for improving skin pores μm²

TABLE 4 test results of moisturizing and hydrating

From the above results, it can be seen that the honeydew prepared in example 4 has the best effect, and the test under the same conditions shows that the improvement of skin pores and the increase rate of moisturizing are the highest, which indicates that the improvement of skin pores and the moisturizing effect of example 4 are the best. After 3 weeks, the skin pore area is improved by 49.68 percent, and the skin moisture content is increased by 52.57 percent.
