Cosmetic composition enhancing skin luminosity and transparency

The present invention relates to a cosmetic composition that improves skin radiance and transparency, and more specifically, by containing herbal extracts such as baekhwasajeol extract, polyol and spherical silicone powder to improve skin transparency and increase dermal layer collagen density to increase skin radiance. It relates to a cosmetic composition that provides the effect of improving the appearance to look more clear and bright.

The chromaticity of the skin is an atomic group contained in three chromophores such as melanin, collagen and hemoglobin (chromophore, an organic compound that causes the development of dyes or pigments) and contains unsaturated bonds. Will appear). Melanin and hemoglobin absorb 400-600nm of light, which is the lowest of the visible range (400-800nm). In general, the less melanin, the whiter the skin appears, but when it is seen by the human eye, the components of the clear and bright skin are not only the contents of melanin, but also the role of skin transparency and brilliance. The transparency of the skin is determined by the amount of light transmitted by the skin itself, and the density of the dermal layer of collagen affects the radiance from the skin when receiving light from outside. As described above, by reducing surface scattering caused by irregular skin surface and making the skin refractive index constant, light transmittance can be increased and skin transparency can be increased. In addition, uniformly increasing the density of collagen in the dermal layer may increase the brightness or aura of the skin by making the angle of deep scattering into and out of the skin constant.

Optical Clearing Agent increases the water content of the stratum corneum and has the effect of keeping the refractive index of the epidermis constant. Physically smoothing the surface of the skin and reducing scattering can increase the degree of light transmission, making the skin layer more optically transparent (see Paper: Optical Interactions with Tissue and Cells XVI, Volume 5695, pp. 278). -287). Since polyols such as glycerin have an excellent water trapping effect, the effect of keeping the refractive index of the skin constant can be expected. In addition, it can be expected that the synergistic effect of the Optical Clearing Agent may occur when the spherical powder is combined with the polyol by filling the unsmooth skin texture and making it physically smooth.

Antioxidant and melanin inhibitory effects of P. vulgaris extract are already known, in addition to promoting collagen production was observed. When the collagen density of the dermis is increased, not only the skin elasticity but also the deeper scattering of the skin due to the increase of the dermal density are improved, so that the angle of light entering and exiting the skin is constant and the amount of light emitted is increased. It is expected to increase the brilliance of.

On the other hand, if the extract is used in combination with beta-hydroxy acid (BHA), wormwood extract, it suppresses the formation of skin melanin cells, skin such as blemishes, freckles, and blemishes There is a patent that discloses that the skin whitening effect is prevented or improved by the pigmentation phenomenon.
