Description

A cosmetic composition with excellent skin tone, skin texture, blemishes, blemishes, gloss and elasticity improvement effect {A COSMETIC COMPOSITION HAVING EXCELLENT EFFECT OF IMPROVING SKIN TONE, TEXTURE, BLEMISH, LUSTER AND ELASTICITY}

The present invention relates to a cosmetic composition having excellent effects of improving skin tone, skin texture, blemishes, blemishes, gloss and elasticity.

The skin is the largest tissue of the human body that occupies the outermost part of the body, and plays an important role as an epithelial tissue that protects various organs, muscles, and bones in the body from the outside. In addition, the skin has functions such as temperature regulation, sensory function, and vitamin D synthesis.

The skin is composed of several layers, and it is largely composed of the epidermis, dermis, and subcutaneous fat. Among them, the epidermal layer is composed of the basal layer, the stratum corneum, the granular layer, the transparent layer, and the stratum corneum from the bottom. The basal layer is in contact with the dermal layer below it, and mainly consists of melanocytes and keratinocytes, which determine skin color, in a ratio of about 1:10, and is in contact with an average of 36 keratinocytes per melanocyte. Although the number of melanocytes is constant regardless of ethnicity and skin color, it is determined by the number of melanosomes, crease, the degree of melanization, the distribution of melanosomes, and the degradation of melanosomes in keratinocytes.

The dermis accounts for 90% of the skin, and collagen fibers and elastic fibers are woven in a net shape to support the skin. Involved in metabolism and water retention.

On the other hand, the generation of active oxygen in the skin of the living body is generated over various routes, 2 to 3% of the oxygen breathed, UV rays, cigarette smoke, air pollution, etc. are generated. The generated active oxygen reacts with the unsaturated fatty acid in the cell membrane to form a new radical, a peroxidation radical, and causes a chain reaction to become lipid peroxidation. Peroxidation of lipids increases the permeability of the cell membrane by reducing the liquidity of the cell membrane. These reactive oxygen species increase the collagenase (MMP) in the dermis, which destroys the matrix protein structure and lowers the fibroblast function, causing the skin to lose its elasticity.
