Description

Technical Field

[0001] The invention relates to the technical field of biomedicine, and in particular to a traditional Chinese medicine mask for removing acne and inflammation, removing spots and whitening skin, and application thereof. Background Art

[0002] With the rapid development of social economy and the improvement of people's living standards, modern consumers have an increasing demand for skin care, especially in terms of acne and inflammation, freckle removal and whitening. Currently, skin care products on the market are mainly divided into products based on chemical ingredients and products based on natural plant ingredients. These two types of products have their own characteristics, but in actual application, it is still difficult to fully meet consumers' comprehensive requirements for safety, effectiveness and convenience.

[0003] Acne removal and whitening products based on chemical ingredients are widely used because of their quick effects, but their potential side effects and long-term safety issues are worrying. For example, although chemical ingredients such as benzoyl peroxide and hydroquinone can effectively remove acne or whiten the skin, they are often irritating to the skin, especially for people with sensitive skin, who are prone to redness, swelling, stinging and other discomforts. In addition, some chemical ingredients can easily damage the skin barrier, and long-term use can even easily cause pigmentation or other skin problems. On the environmental level, chemical skin care products are prone to pollution during production and use, which does not meet people's current requirements for green environmental protection.

[0004] In contrast, traditional Chinese medicine skin care products are increasingly favored by consumers due to their natural and safe characteristics. The rich bioactive ingredients in traditional Chinese medicine have significant anti-inflammatory, antibacterial and whitening effects, and can act gently on the skin to reduce adverse reactions. However, traditional Chinese medicine skin care products still need to be optimized in terms of absorption efficiency, efficacy stability and storage convenience. For example, traditional Chinese medicine masks are often used in the form of coarse powder or decoction, and the skin's absorption efficiency of its active ingredients is low, affecting the actual effect. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a Chinese medicine facial mask for removing acne and inflammation, removing spots and whitening, and its application, to solve the problems of poor absorption, unstable efficacy, complex preparation process and insufficient safety of traditional Chinese medicine skin care products.

[0204] The melanin reduction rate was 18%, and the simulated skin appeared noticeably rough.

[0205] Analysis: Low antibacterial activity, simulated skin irritation and damage.

[0206] The analysis results are shown in the following table:

[0207]

[0208]

[0209] Result analysis:

[0210] Preferred formula:

[0211] Experimental Example 1 has a balance between antibacterial effect and whitening effect, and the skin model is smooth and undamaged, with high safety. It is suitable for most skin types and is not prone to dryness or irritation.

[0212] Other experimental examples for comparison:

[0213] Experimental Example 5 performs better than Experimental Example 1 in terms of antibacterial and whitening properties, but the proportions are slightly higher (for example, the proportions of Radix Trichosanthis and Radix Rhei are higher), which may be unpleasant to some sensitive skin types.

[0214] Experimental Example 3 has outstanding whitening properties, but the high content of white Poria cocos may cause the skin to feel dry and is not suitable for dry skin.

[0215] Proportional disadvantages:

[0216] When the formula exceeds the specified range, the antibacterial and whitening properties are greatly reduced, and obvious safety issues (such as skin damage and roughness) arise.

[0217] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
