Description

[0001] The present invention relates to a cosmetic composition containing extracts of gabbro and a mixture of a hibiscus tree and a hibiscus tree. [0002] The present invention relates to a cosmetic composition containing extracts of Daphneophyllum macropodum and Cleyera japonica,

The present invention relates to a cosmetic composition containing a mixture of ginkgo tree and a mixture of ginkgo tree, and more specifically, to a cosmetic composition containing an extract of ginkgo tree and a mixture of ginkgo tree as an active ingredient and exhibiting excellent ultraviolet blocking activity.

Most people are able to cope with sunlight easily during their growing season, but as their age gradually increases, skin texture gradually changes, causing sunlight-induced wrinkles, thickening and sagging skin, loss of skin elasticity, roughness and dryness And skin irregularities occur. The term collectively referred to as photo-aging is the result of accumulation of such effects by daylight. Such skin photo-aging is a phenomenon in which the epidermis and dermis changes in the skin due to sunlight in a weakened response to light, wrinkles occur, and the elasticity gradually decreases as the skin becomes yellowish and thick.

Particularly, as the level of culture has rapidly increased with the acceleration of the industrial society in recent years, the seriousness of indoor and outdoor air pollution by the increase of the number of automobiles, heating, and air conditioners is becoming more and more serious. Furthermore, the combination of destruction of the ozone layer by nitrogen compounds and environmental pollution Air pollution caused by environmental factors. Because of this phenomenon, ozone warnings are sometimes issued. In spring and autumn, contact dermatitis due to the spread of allergens such as pollen is increasing day by day. In addition, water pollution caused by industrial wastewater and domestic sewage is spreading, and soil pollution is increasing day by day.

On the other hand, as the overall level of culture has improved, the desire for the meaning of consumers using cosmetics has also been improved. In other words, as the perception of the effect of skin photoaging and pollution on the skin has spread, cosmetics have been found to be more effective than moisturizing, nutritional supply, and skin beauty to alleviate and improve the appearance of wrinkles of skin, whitening effect, ultraviolet ray blocking effect, There is a growing need for a functional product having such activity. In fact, the development and launch of such a functional product is gradually being activated.

The mechanisms by which ultraviolet rays are harmful to skin are as follows. In other words, keratinocytes in skin cells secrete cytokines and the like when irradiated with ultraviolet rays, and oxidative stress is induced, thereby activating various kinds of proteins in cells. Activated enzymes hydrolyze cell membrane lipids, so that arachidonic acid is secreted in these cells. In addition, secreted arachidonic acid is converted to prostaglandin E2 (PGE2) by the action of cyclooxygenase. The arachidonic acid and PGE2 thus formed cooperate with cytokines to cause various inflammations including erythema in the skin and further promote skin aging. In addition, connective tissue cells in skin cells are activated by a process similar to activation of keratinocytes by irradiation of ultraviolet rays, and may be killed as the amount of ultraviolet rays is increased. Furthermore, skin aging is promoted by DNA damage and the like, which may cause skin cancer. Ultraviolet rays cause skin redness, immunosuppression, wrinkle formation, skin aging, skin cancer and the like. Therefore, blocking of ultraviolet rays is very important. Therefore, development of a functional cosmetic having such ultraviolet blocking activity is further demanded.
