Aging of the skin is a natural phenomenon inevitably occurring with age, rather than skin abnormalities, and is not a skin disease. However, the demand for quality of life is increasing due to the improvement of the standard of living, and the recent aging of the skin, which has been confirmed that the aging of the skin is progressed by the sun, which had been favored in the past, is clearly desired for healthy and beautiful skin. It was against the winds of all modern man. In a situation where the threat of skin aging is increasing due to various environmental factors, measures for skin aging are urgently required.

The most basic and necessary thing for your skin is moisturizing. After moisturizing, there are many things that can happen. Degradation of skin regeneration causes rough skin, reduced elasticity, wrinkles, and dull skin tone.

Recently, the amount of ultraviolet rays reaching the surface due to environmental pollution is increasing, and the possibility of exposure to ultraviolet rays is increasing due to the increase in leisure and outdoor activities. Therefore, care for skin roughness and wrinkles has become more important due to photoaging.

The skin produces new skin cells every 28 days, pushing old cells into the stratum corneum. This is called the cell turn-over cycle. Since the age of 25, a woman's skin regeneration cycle is prolonged for various reasons, causing skin troubles, skin dullness, water retention, roughness, and fine lines. Especially during the cold and dry season, the skin is deprived of moisture and becomes rough and dry. In addition, as the metabolism slows down, the secretion of sweat and sebum decreases drastically, and as the skin becomes more dry, unnecessary dead skin is further increased and dried on the surface of the skin.

Therefore, consumers have a variety of effects, there is a growing demand for cosmetics that can be used with confidence without objection.

In addition, in the recent external environment, the use of animal raw materials that can cause mad cow disease due to ripples such as mad cow disease has been banned, and the use of animal raw materials has become a trend, and consumers' preference for vegetable raw materials has increased. According to this social trend, the necessity of vegetable raw materials having various effects is emerging.

Thus, the present inventors investigated the plants capable of raw materialization of the vegetable origin, and carried out the data research of the plants on the premise that they can have a complex effect. As a result of investigating the vegetable origin in consideration of whether the commercialization is possible due to the sufficient supply of raw materials and the economic feasibility of commercialization, it was confirmed that the snow drop extract was excellent in moisturizing effect, skin regeneration effect, elasticity improvement and skin color brightness improvement effect. To complete.

Accordingly, it is an object of the present invention to provide a cosmetic composition excellent in skin moisturizing effect, anti-aging effect, skin elasticity improvement and skin color brightness improvement effect by containing a snow drop (snow drop) extract as an active ingredient.

In order to achieve the above object, the present invention provides a cosmetic composition containing a snow drop (snow drop) extract as an active ingredient.
