Description

Composition with pore shrinking effect, essence water, preparation method and application

Technical Field

The invention relates to the technical field of cosmetics, and particularly relates to a composition with an effect of shrinking pores, essence water, a preparation method and application.

Background

Along with the continuous improvement of living standard of people, the heavy visibility of people to the self image is also improved, and people hope to have a beautiful image. In the current society, beauty is closely related to skin state, and fine and uniform skin is one of the important standards for healthy and beautiful skin. In addition to the increase of sebum function and the blockage of greasy dirt of oily skin, unhealthy life styles such as skin laxity, water shortage, incorrect cleaning style, frequent staying up all night and irregular work and rest and bad habits all cause skin pores to be large and further affect the state of skin along with the increase of age.

The pore size can be classified into horny pores, water-deficient pores, and aged pores according to the cause of pore size. The horny pores are large because the horny layer blocks the pores, old horny on the surface of the skin is poor in metabolism, the pores are blocked, and finally the pores are enlarged, so that the T-shaped parts of the face are often oily and shiny, and the pores are blackened; the water deficiency type large pores are that when skin is dry due to water deficiency, the moisture of stratum corneum is reduced, and the skin is easy to dry and has long wrinkles, so that the large pores on two sides of the nose are formed; the reason that old pores are large is that collagen and elastin in the body become fine and fragile with the age, and cannot effectively support the skin, so that the skin around the pores is in a loose and sunken state, and the pores are expanded to be in a water drop shape.

The solution is different according to different causes of pore size. However, skin care products with large pores on the market generally only have a single function of astringing pores, and only can improve one of water-deficient pores, aging pores and horny pores, so that the efficacy is not obvious enough.

The specific method comprises the following steps: 1) selecting a tested person group: the test population is 100 healthy subjects, the age is 18-35 years old, oily skin, large pores in facial skin, healthy skin of the subjects, no allergic history of skin diseases and according with the volunteer selection standard of the subjects; 2) allergic reaction patch test: taking 0.02mL of sample by using a quantitative pipette, placing the sample in a medicine chamber of a spot tester, longitudinally sticking a hypoallergenic adhesive tape for the spot tester on normal skin of the bent side of the left forearm of a subject from the lower part, lightly pressing with the palm to uniformly stick on the skin, removing after 24 hours,marking the test part for observation, and observing the skin reaction of the test part 0.5h, 6h, 12h, 24h and 48h after the spot tester is removed; 3) pore detection: applying the sample to the concentrated part of the large pores on the face of a subject, wherein the applying amount is 2mg/cm, waiting for 3min to allow the tested sample to naturally dry, respectively counting the pore areas of the sample before use, the sample after 0 day, 7 days, 15 days and 28 days by using a Roboskin analyzer, and analyzing the data before and after using the sample to improve the large pore effect to ensure that the visible pore area is mum²It is shown that the larger the improvement rate, the more significant the effect of improving the pore size of the test sample. The specific test results are shown in table 1 below.

TABLE 1 skin pore area test results

In the allergy patch test, the results show that: the skin reactions of the test sites were observed at 0.5h, 6h, 12h, 24h and 48h by patch tests of the compositions with the pore-shrinking effect obtained in examples 1 to 18, the essence waters obtained in examples 20 to 24 and the essence waters obtained in comparative examples 1 to 4 on all the subjects, and no adverse skin reactions occurred on all the subjects, which indicates that the samples prepared in the examples of the present invention are safe to use.

From the above results, it can be seen that the essence prepared in example 18 has the best effect, and the skin pore improvement rate is the highest when tested under the same conditions, which indicates that the skin pore improvement effect of example 18 is the best, and the skin pore area is improved by 54.78% after 4 weeks.

It should be noted that the improvement rate of example 18 is 54.78%, the improvement rate of comparative example 1 is 48.14%, although 54.78% and 48.76% are not numerically different, but it is more difficult to improve the skin pores as the addition amount of the extract is larger, the allantoin has a soothing, softening and protecting effect, the addition of allantoin, which is combined with the synergistic effect of hamamelis water, fomes officinalis extract, oligopeptide-1, has a keratolytic effect, and the keratinocytes can be removed by relaxing intercellular substances or maintaining bridge particles (protein bridges) where the keratinocytes are mutually bonded, so that the skin surface is smoother, more delicate and more flexible; can prevent skin inflammation, and can also play a role in horny pore enlargement, thereby playing a role in three different types of pores such as horny pore enlargement, water-deficient pore enlargement and aged pore enlargement, and improving the skin pore enlargement situation.

It is further noted that allantoin increases the water retention of the skin, enhances the natural protective barrier of the skin by enhancing the water binding capacity of keratinocytes, enhances the moisturizing properties, and provides a smoothing effect to the skin; the hamamelis virginiana water can effectively relieve facial cells of a human body, is rich in relieving factors, can play a role in calming and soothing skin cells, can well moisten the skin, and also has the effect of convergence; the medicinal fomes fomentarius extract has effects of astringing and reducing pores, tightening skin and keeping moisture; oligopeptide-1 promotes epidermal cell proliferation and differentiation, and promotes synthesis of type I collagen, type III collagen and glycosaminoglycan, thereby having effects of epidermal regeneration and repair, collagen supplement, anti-aging, wrinkle improvement, etc.

The composition with the effect of shrinking pores provided by the invention comprises the following raw materials: allantoin, Hamamelis virginiana water, medicinal fomes officinalis extract and oligopeptide-1, and the composition has multiple effects of softening cutin, mildly removing keratinocyte, keeping moisture, simultaneously astringing skin, shrinking pores and the like, can improve skin pores in a coordinated way in multiple directions, achieves excellent effect of shrinking the pores through the synergistic effect of allantoin, hamamelis water, medicinal fomes officinalis extract and oligopeptide-1, achieves the comprehensive skin care effect by adopting a specific proportion, and the improvement rate of the pore area can reach more than 54 percent, can astringe and reduce pores, tighten skin, keep moisture for a long time, improve wrinkles, prevent skin aging, adjust stratum corneum, improve skin transparency, enhance moisture retention effect and skin barrier function, the cosmetic composition can also play a role in horny pores, and thus can play a role in three different types of pores, namely horny pores, water-deficient pores and old pores. The provided preparation method is simple, the formula is very mild, no stimulation is generated, the use is safe, the problems that the existing skin care product aiming at the problem of large pores generally has single effect and cannot simultaneously improve the large situation of various types of pores are solved, and the skin care product has wide market prospect.

While the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the scope of the invention.
