Cosmetic composition for sensitive skin and scalp {Cosmetic composition for sensitive-skin and scalp}

The present invention relates to a cosmetic composition for sensitive skin and scalp, specifically, to prevent and alleviate inflammation and itching occurring in the skin and scalp through the control of inflammatory mediators, safe to the human body and have no side effects even after long-term use In addition, the present invention relates to a cosmetic composition for sensitive skin and scalp having an excellent moisturizing effect.

Sensitive skin is typically defined as skin that exhibits better contact irritation or allergic reactions than the average population. Sensitive scalp and skin can easily break skin normalization mechanism by external stimulation, which can cause hypersensitivity reactions such as erythema, edema, tingling and itching. In addition, sensitive skin easily responds to erythema, swelling, tingling, and itching in certain substances contained in excessive ultraviolet rays, daily hair products, and skin care products due to the destruction of the ozone layer. Recently, sensitive skin is gradually increasing due to environmental pollution, lifestyle changes, and stress, and it is also a social problem.

Hypersensitivity reactions in sensitive skin or scalp include cytokines and inflammatory mediators, and interleukin-1 (IL-1) when hypersensitivity follows the inflammatory pathway of contact irritant It is known to be involved. The main chemical delivery mediators that cause inflammatory reactions are amines such as histamine or serotonin, kinines such as bradykinin, prostaglandins, leukotrienes, cytokines and the like. It has been reported that various cytokines, prostaglandins (particularly PGE ₂ ) and the like are involved in vasodilation and edema formation, causing inflammation and pain.

Conventionally, in order to prevent the induction of hypersensitivity reactions, only the components that are likely to cause hypersensitivity reactions were removed from the cosmetic components. However, sensitive skin holders also need to use cosmetics that contain ingredients that may cause irritation, so cytokines or inflammation that are the root cause of skin hypersensitivity rather than simply using ingredients that may cause hypersensitivity reactions. It is necessary to alleviate hypersensitivity reactions through the control of mediators. Conventional anti-inflammatory components such as aspirin and indomethacin have been widely recognized for their effects, but side effects such as gastrointestinal disorders and antivascular expansion are known, and antagonists to neuropeptide-based components including substance P, bradykinin, etc. Anti-inflammatory components such as antagonists and cyclooxygenase inhibitors against nin are limited in scope and level of use due to legal issues such as human safety, stability in the product, restriction on the amount used.
