Background

Acne, commonly called acne in traditional Chinese medicine, is a chronic inflammatory disease occurring in pilosebaceous glands, mainly occurs in the head, face and chest and back, and is the most common dermatosis with skin lesions. The people who are easy to grow the acne are mainly teenagers and often occur on the face, and severe acne can cause damage to compatible scars, easily affect the mood of consumers and even interfere the daily life of the consumers. Acne is caused by hyperactivity of sebaceous glands, resulting in imbalance between sebum production and discharge, excessive keratinization of hair follicles, the action of bacterial lipase produced by bacteria (mainly acne bacillus, etc.) decomposes triglyceride in sebum to produce free fatty acid, which stimulates inflammation of hair follicle to break hair follicle wall injury and allow hair follicle content to enter dermis, thereby causing inflammatory reactions of varying degrees around the hair follicle, since the inflammation promotes the presence of oxygen radicals, these acids are easily peroxidized to increase the inflammatory attack, and from this mechanism, it can be seen that acne, which is manifested as papules and partial whiteheads when it is just formed and not oxidized to further worsen, is not directly caused by acne, and is classified as primary acne, mature acne in which free fatty acids are oxidized by oxygen radicals to form pustules and nodules, etc., which are more difficult to remove and leave scars after treatment.

2. Verification of effects

The judgment results of the acne removing efficacy of the sample propionibacterium acnes bacteriostasis test and the results of DPPH and ABTS free radical clearance rate test are shown in Table 3:

table 3: antibacterial and antioxidant effects

Test set	Acne removing efficacy (bacteriostasis)	DPPH radical scavenging ratio (%)	ABTS radical scavenging ratio (%)
				Group 1	Low efficiency	85.32	77.38
Group 2	Low efficiency	78.46	73.56
				Group 3	Low efficiency	80.12	74.66
Group 4	Low efficiency	77.99	72.36
				Group 5	Low efficiency	60.31	57.56
Group 6	Middle effect	85.69	80.11
				Group 7	Low efficiency	62.66	62.75
Group 8	Low efficiency	60.11	58.00
				Group 9	Low efficiency	63.74	63.44
Group 10	Low efficiency	77.99	72.18

The results show that the bacteriostatic effects of groups 1-10 are all low, and the bacteriostatic effect of group 6 is moderate. However, the radical scavenging effect was strong in each group, and the groups 6, 1, 3, 2, 4, and 10 were in this order. The inhibition of propionibacterium acnes and the removal of free radicals are two important conditions for producing an anti-acne effect, and the two conditions complement each other. The composition disclosed by the invention has a low antibacterial effect, but can generate an acne removing effect through a good effect of removing free radicals.

Therefore, the essence has the anti-acne effect with different degrees.

Table 4 specific use case grouping

TABLE 5 Consumer use Effect scoring results

As can be seen from Table 5, each group had certain acne removing and acne preventing effects.

Wherein the groups 1-4, 6 and 10 have higher scores in the aspects of the acne prevention effect and the acne removal effect. This indicates that these groups of samples can achieve good anti-acne and anti-acne effects by scavenging free radicals. The groups 5 and 7 to 9 had low scores in both the anti-acne effect and the anti-acne effect, and could not exert a good anti-acne effect, which was consistent with the effect of scavenging free radicals described in table 3.

The samples of groups 6 and 10 were inferior in irritation to the other samples, and the subjects considered that the samples were somewhat irritating and not mild enough.

In combination with the results, the anti-acne and anti-acne component provided by the invention can realize good anti-acne and anti-acne effects through removing free radicals and matching with the nano-gold and the allergy-relieving component,

comparing group 3 with groups 7 to 9, it can be seen that the anti-acne and anti-acne component provided in example 1 with the same amount has better effect of scavenging free radicals and better effect of preventing acne and removing acnes compared with comparative examples 1 to 3 which lack some components. The components for preventing and removing the acnes are reasonable in composition and all the components are absent. However, excessive addition of this component can cause irritation and is not conducive to use by people with sensitive skin. Therefore, the amount of the anti-acne and anti-acne component added to every 100g of essence is 0.5-1.0 g.

Comparing the samples of groups 1-6, it can be seen that the effect of the acne removing component of the invention can be further improved by adding nanogold, and the effect of the sample added with nanogold is better than that of the group 5 without adding nanogold in the aspects of oxidation resistance, acne removing and acne preventing. In addition, in a certain concentration range, the content of the nano-gold is increased, so that the effects of resisting oxidation, preventing acnes and removing acnes can be improved, but because the cost of the nano-gold raw material is high, the addition amount of the nano-gold in every 100g of essence is more appropriate from the comprehensive consideration of ensuring the using effect, the mildness and the cost.

Comparing group 10 with group 3, it can be seen that group 3 with the addition of the soothing component does not exhibit irritation at the same amount of the anti-acne component and nanogold, while group 10 receives feedback of higher irritation, and the soothing component provided by the present invention can reduce skin sensitivity.

The essential liquid of the group 1-3 is considered in all aspects, and good acne prevention and removal effects are obtained by removing free radicals and reducing sensitivity, so that the reasonable components and the appropriate concentration are shown.
