Description

Skin anti-aging composition and application and skin care product thereof

Technical Field

The invention belongs to the technical field of skin care products, and particularly relates to a skin anti-aging composition and application thereof, and a skin care product.

Background

With the research development of skin care product science and the increasing demands of consumers on the efficacy of skin care products, anti-aging skin care becomes one of the most important consumer appeal. Research shows that the skin gradually enters a natural aging state from 20 to 25 years old, and the aging speed is different according to the genetic genes and living habits of each person. Due to the influence of factors such as fast-paced life, stay up, working pressure and the like, the primary and old appearance of skin of a part of young consumers aged 20 years is obvious, including dry and tight skin; facial relaxation sags slightly; fine lines appear on eyes; neck lines appear; slow recovery after tanning, etc. The anti-aging is to make various anti-aging works in the early stage of skin aging and delay the aging speed.

Human skin is composed of epidermis, basement membrane and dermis, and the actions of fibroblasts located in dermis include production of collagen, elastin, and dextran, etc., which have the actions of maintaining skin elasticity, dermis moisturizing, etc. The activity of fibroblasts plays a vital role in maintaining a healthy appearance of the skin. It has been observed that with age, the proliferation of fibroblasts and the function of synthesizing skin benefit ingredients gradually decrease.

Vitamin A is a very classical skin care ingredient which acts on the epidermis of the skin, promotes cell proliferation, maintains normal circulation of the skin, repairs lost collagen, reduces signs of wrinkles and premature aging (such as abnormal pigmentation, rough spots and dry skin), and has the effects of removing wrinkles and resisting photoaging. Vitamin a does not refer to a single chemical substance, but includes retinol (retinol, a alcohol), retinaldehyde (a aldehyde), retinoic acid (a acid), collectively referred to as Retinoids (Retinoids). However, there are different levels of irritation, whether acids, aldehydes, ketones, alcohols, or esters, and consumers experience discomforts such as molting, redness, stinging during use.

Thus, finding a safer, non-irritating ingredient to combat skin that has similar efficacy to vitamin a is an increasing concern for researchers in this field. As a result of the efforts of researchers in this field, many plant-derived, retinoid components have been discovered which are characterized as mild. They can in some ways even exceed the retinoids in terms of skin anti-aging ability, but none of the ingredients can mimic the effects of vitamin a in all directions.

The technical scheme of the present invention will be clearly and completely described in the following in connection with the embodiments of the present invention,

it will be apparent that the described embodiments are only some, but not all, embodiments of the invention.

The embodiments described below are exemplary and intended to be illustrative of the invention and should not be construed as limiting the invention

And are clearly limiting.

Example 1: an antiaging composition comprises bakuchiol 6 parts, herba Bidentis Bipinnatae extract 24 parts, and herba Medicaginis extract 70 parts.

Example 2: an antiaging composition comprises bakuchiol 5 parts, herba Bidentis Bipinnatae extract 20 parts, and herba Medicaginis extract 75 parts.

Example 3: an antiaging composition comprises bakuchiol 15 parts, herba Bidentis Bipinnatae extract 60 parts, and herba Medicaginis extract 25 parts.

Example 4: an antiaging composition comprises bakuchiol 20 parts, herba Bidentis Bipinnatae extract 40 parts, and herba Medicaginis extract 40 parts.

The three components of bakuchiol, bidens pilosa extract and alfalfa extract have targets similar to the vitamin A on the skin, but can not be completely simulated. The alfalfa extract has high coincidence degree with vitamin A in the aspect of epidermal cell gene regulation, but does not influence the gene expression of vitamin A receptor (CRBP 1, CRBP 2), and bakuchiol has regulation and control effects on the two genes. In addition, bakuchiol provides similar activity to retinoids in terms of retinol binding and metabolic genes. However, alfalfa extract and bakuchiol have no regulatory effect on both the RARs and RXRs receptors. Whereas Bidens pilosa extract has a regulatory effect on both receptors. Table 1 shows important regulation targets of vitamin A on skin, and the regulation capacities of different components on different targets are shown in Table 1.

The results in table 1 show that: by comparing the regulation and control capability of bakuchiol, bidens pilosa extract and alfalfa extract on different targets, the combination and collocation of the three active ingredients can well simulate all important skin regulation and control functions of vitamin A (except RARs receptor). And the increased expression of RAR receptor is the main cause of redness, desquamation and fever of skin when using vitamin A products. Vitamin A can stimulate the increase of RAR receptor expression, and the combination and collocation of the three active ingredients can not stimulate the increase of RAR receptor expression, but can inhibit the expression to a certain extent, thereby reducing the occurrence of the phenomena of redness, desquamation and fever of skin. In addition, the bakuchiol has strong oxidation resistance, and the oxidation resistance of the other two components is improved by matching the bakuchiol, the bakuchiol and the bakuchiol together. In addition, the bakuchiol and the Bidens pilosa extract are both oily and sticky, and the alfalfa extract is a water-soluble extract, so that the use amount of the bakuchiol and the Bidens pilosa extract is correspondingly reduced by matching, and the sticky feel of the final product is reduced.

The composition provided by the invention has the advantages of milder effect, good skin aging resistance and the like, which are further proved by corresponding experimental data.

Experiment 1: the compositions were tested for mildness by comparison, as shown in Table 2.

60 Chinese healthy female subjects were selected, with an age ranging from 20-30 years, with an average age of 26.3.+ -. 3.5 years. The random groups were divided into 2 groups, the first group using an emulsion containing 0.3% retinol, the second group using the emulsion of example 6, used at night daily for 3 consecutive days, and then the skin condition after use was evaluated.

Table 2 consumer evaluation after skin application

Symptoms appear	Using retinol groups	Use of example 6 group
			Reddening and skinning	50%	0
Acne-breaking	40%	0
			Fever and stinging pain	16.7%	0
No uncomfortable feeling is generated	0	100%

Note that: the appearance symptoms are multiple choice questions.

As can be seen from table 2: the essence prepared by the composition has no uncomfortable feeling in the use process. In contrast, the control group using 0.3% retinol showed all skin discomfort, different symptoms in different proportions, and some subjects even showed more than one skin problem. It follows that the skin care products containing the composition are much milder to the consumer than retinol.

Experiment 2: fibroblast activity promoting effect is shown in tables 3-4.

The combination of the three actives in the anti-aging compositions of the present invention resulted in comparative examples 1-6 and inventive example 4 for cell experiments.

		Comparative example 2	18.23
Comparative example 3	15.11
		Comparative example 4	20.32
Comparative example 5	23.26
		Comparative example 6	21.83

As can be seen from Table 4, the amounts of bakuchiol, bidens pilosa extract, and alfalfa extract, respectively, increased by 17.91%, 18.23%, and 15.11% for type I collagen synthesis. And the corresponding increase of type I collagen synthesis is 20.32%, 23.26% and 21.83%. However, three components were present (example 4), and the increase in type I collagen synthesis was 38.91%. The same experiment was performed using examples 1 to 3 and example 5 of the present invention, wherein the increase in synthesis of type I collagen was 37.25% in example 1, 39.13% in example 2, 38.50% in example 3, and 39.67% in example 5. The experiment proves that the three active components are compounded and have synergistic effect.

Experiment 3: human efficacy evaluation tests are shown in tables 5-7.

30 female subjects were selected, aged 25 to 50 years, with an average age of 35.6.+ -. 7.5 years. The subjects used the emulsion of example 7 once a day, both early and late, and a 14 day and 28 day visit, at the same time during the day, during which the same other type of product had not been used. Before testing, the subject sits still in a constant temperature and humidity waiting area with the temperature of 21+/-1 ℃ and the relative humidity of 50+/-10% RH for 20 minutes; the inspector collects the values of the skin elasticity parameter R2, the skin firmness parameter F4, and the values of Sa, sq, and SV of the skin in the cheek region of the subject.

Note that: p value < 0.001. Rate of change = (post-use measurement-pre-use measurement)/pre-use measurement 100%. The higher the rate of change, the higher the skin elasticity increase.

Table 5 shows: the skin elasticity changes before and after 28 days of application of the product. The value of the cheek region skin elasticity parameter R2 was significantly increased by 29.36% 28 days after the application of the product, compared to before the application of the product. The composition can significantly improve skin elasticity.

Table 6 skin firmness parameters F4 descriptive statistics (Cutometer MPA 580) (n=30)

Note that: p value < 0.001. Rate of change = (post-use measurement-pre-use measurement)/pre-use measurement 100%. For the value of the firmness parameter F4, the lower the value, the better the skin firmness is indicated.

Table 6 shows: changes in skin firmness around 28 days after application of the product. The cheek region skin firmness parameter F4 was reduced by a few 42.32% significantly 28 days after product use compared to before product use. Indicating that the composition can significantly improve skin firmness.

Test index	D0 (before using the product)	D28 (use product for 28 days)	Rate of change
				Sa	26.3±4.6	20.5±4.3	-22.05%
Sq	34.3±7.8	28.7±6.5	-16.32%
				SV	-180.6±21.5	-168.6±19.8	6.64%

Note that: p value < 0.05.

As can be seen from table 7: after the subject used the emulsion containing the composition, the test showed that the Sa and Sq values decreased and the SV value increased over time. The composition is shown to be effective in improving skin wrinkling. According to the mechanism of wrinkle formation and the appearance of skin state, the skin elasticity, the compactness and the wrinkle condition can be combined with the anti-aging effect of the average product, and the combination of the test data shows that the skin care product containing the composition has obvious anti-aging effect.

The same human body efficacy evaluation test experiments are carried out by adopting the embodiment 6 and the embodiment 8 of the invention, and the skin care product disclosed by the embodiment 6 and the embodiment 8 can obviously improve the skin elasticity, the compactness and the obvious anti-aging effect.
