Anti-allergy composition and preparation method and application thereof

Technical Field

The invention relates to the technical field of cosmetics, in particular to an anti-allergy composition and a preparation method and application thereof.

Background

With the change of the external environment and the daily life habits of people, the life pressure is increased, the resistance of the people to the external environment begins to decline, and the frequency of the sensitive problems of the skin with different sexes or different age stages is continuously increased. Uncontrollable factors such as ultraviolet rays, climate and the like can cause skin sensitivity. Meanwhile, with the improvement of living standard and the acceleration of living rhythm, more and more consumers pay more attention to products with high efficacy and quick effect, and the micro-shaping of medical science and beauty also becomes a heat bar. Frequent use of highly effective and quick-acting cosmetics by consumers, even blind selection or use of poor quality products and inappropriate medical and aesthetic means, causes more and more external invasion of the skin, the skin barrier function becomes more and more fragile, many adult consumers and even teenagers suffer from sensitive skin, and the decline of the skin defense causes a list of skin problems such as stinging, itching, dry skin and the like.

There are many factors that induce skin sensitivity, including endogenous factors and exogenous factors. Endogenous factors such as lifestyle habits or body's autoimmune problems can cause skin sensitivity. Exogenous factors such as excessive cleansing, use of high efficacy cosmetics or inferior cosmetics, cosmetic film materials or environmental factors, etc. The consumer does not clearly judge the sensitivity of the consumer to the skin of the consumer, and common anti-skin-sensitivity products in the market are mainly used as entry points in the aspects of anti-inflammation moisturizing, skin micro-ecological balance or barrier repair, and generally the products have good relieving and regulating effects on some aspects of skin sensitivity, so that people with sensitive skin are difficult to regulate and improve the sensitive skin state by using one product, the skin sensitivity cannot be immediately and effectively relieved, and the selection of the products by the consumer is also greatly limited, for example, the use selection of some effective products with adaptive reaction in the use process can be greatly influenced, such as whitening, freckle removing and sunscreen products.
