Description

Technical Field

[0001] The invention belongs to the technical field of skin care, and relates to an all-natural composition having the functions of skin barrier repairing, whitening and soothing, and a preparation method and application thereof. Background Art

[0002] Sensitive skin is a type of skin that shows unpleasant feelings such as tightness, tingling, burning, and itching in response to stimuli such as cold, heat, sunlight, and inferior cosmetics. In recent years, with the influence of people wearing masks for a long time, global climate change, and the popularization of electronic products, the problem of damaged skin barrier has become particularly prominent, and the number of people with sensitive skin has increased. Epidemiological studies have shown that the repair of sensitive skin has become a global problem. The "Chinese Expert Consensus on Sensitive Skin Management" reported that the proportion of sensitive skin in Chinese women is 36.1%. Among them, the high-risk population aged 20 to 45 accounts for more than 70%. However, there are very few sensitive skin repair products on the market, and it is difficult to distinguish the authenticity of efficacy claims, making it difficult for people with sensitive skin to choose suitable repair cosmetics. What is particularly important is that the skin barrier is the first line of defense against external aggression. A healthy skin barrier can effectively lock in moisture and resist external stimuli, which is the key to maintaining healthy and stable skin. Therefore, while paying attention to the repair of sensitive skin, strengthening the repair and reconstruction of the skin barrier is of immeasurable value for fundamentally improving sensitive skin problems and improving the overall health of the skin. Developing pure natural and highly targeted skin barrier repair products will be the key to solving this global problem.

[0003] In traditional Asian aesthetics, fair skin is a symbol of beauty and elegance. With the improvement of beauty concepts and living standards, people's demand for skin whitening has continued to rise, and whitening skin care products are very popular. According to Zhixi Consulting data, more than 80% of Chinese female consumers aged 20 to 50 have whitening needs, and China's annual whitening consumer market size is as high as 66 billion. While people with sensitive skin are eager for anti-allergic repair, they can also improve uneven skin tone, dullness and inhibit the formation of various facial spots. Although the whitening product market has been hot in recent years, due to the short development time, the whitening effect research on Chinese skin is still in its initial stage, and there are very few products on the market that are both anti-allergic and whitening, and the authenticity of efficacy claims is difficult to distinguish. Common cosmetic whitening ingredients, such as salicylic acid, arbutin sulfate, citrus oil, etc., will cause certain stimulation to sensitive skin, making it more difficult for people with sensitive skin to choose suitable repair and whitening cosmetics. It can be seen that the development of safe, reliable and effective whitening and repair products is imminent.

[0004] The lotus root industry has a large number of cheap natural lotus leaves. The resource development and high-value utilization of lotus leaves play an important role in promoting the development of Hubei's agricultural economy. Lotus leaf extract is rich in water-soluble nuciferine, flavonoids, polysaccharides and essential oils and other active ingredients. It has the effects of whitening, anti-aging, moisturizing and oil control. It can also gently and effectively help relieve the discomfort of sensitive skin and reduce redness, swelling and irritation. At the same time, lotus has extremely beautiful and rich meanings in Chinese culture, symbolizing purity, nobility and auspiciousness. The green lotus is like a screen, and the fragrance comes from the core. This is the simplest interpretation of the oriental skin care philosophy of lotus. The perfect fusion of lotus leaf extract and organic camellia oil not only achieves the skin care effect of the repair cream, but also gives it a unique cultural connotation and oriental charm.

[0005] Therefore, lotus leaf extract can be used to prepare an all-natural composition that has both skin barrier repair and whitening and soothing effects. Summary of the invention
