Description

Composition for skin regeneration and hair growth promotion including apigenin {Composition for Regenerating Skin and Enhancing Hair Growth Comprising Apigenin}

The present invention relates to a composition for promoting skin regeneration and hair growth comprising apigenin.

Skin exists in the outermost part of the human body and is directly in contact with the external environment, thus protecting the human body from external damage and preventing excessive evaporation of water and heat in the body. The skin is composed of three layers of epidermis, dermis, and subcutaneous tissue. Most of the outermost epidermis is composed of keratinocytes. Keratinocytes in the epidermis protect the skin by forming keratin through the process of proliferation, migration and differentiation from the base layer, and produce various cytokines to participate in inflammatory and immune responses. In addition, proliferation and migration of keratinocytes not only provides wound healing and skin regeneration, but also induces collagen synthesis to improve skin elasticity and basement membrane formation, thereby controlling adhesion and proliferation of skin cells and harmful. It provides an improvement in barrier function that selectively penetrates substances and interaction between the epidermis and the dermis. Due to this, the movement and proliferation of skin epidermal keratinocytes not only improves skin regeneration and wound healing, but also promotes skin elasticity and helps maintain healthy skin.

As the interest in skin beauty has increased, in order to maintain a healthier and more beautiful skin, the unique function of the skin is maintained by using physiologically active substances derived from various natural substances with high safety obtained from various animals, plants, and microorganisms. And various attempts to effectively suppress or alleviate skin aging by enhancing and activating skin cells have been extensively performed.

Apigenin (apigenin) is a nutritional component well known as an antioxidant contained in vegetables, and is used as a component for skin whitening, skin regeneration, and hair growth promotion.

Korean Patent Publication No. 2017-0119757 discloses that a cosmetic composition using apigenin, germanium, and amino acids, can exhibit skin regeneration and stabilizing effects by synergistically expressing the effects of each component.
