Description

The present invention relates to an anti-aging cosmetic that has an excellent moisturizing effect, has an anti-aging effect that makes fine lines due to dry skin inconspicuous, and has a comfortable and comfortable feeling without stickiness.

The skin is composed of epidermal cells, fibroblasts, and extracellular matrices such as collagen, hyaluronic acid, and elastin that form the skin structure outside these cells. In younger skins, these skin tissues interact with each other to maintain moisture retention, flexibility, elasticity, etc., and the skin is kept fresh and fresh. Yes. However, due to the influence of external factors such as ultraviolet rays and drying, and especially with the progress of aging, the amount of collagen, which is the main component of the extracellular matrix, is reduced and the elasticity is reduced due to crosslinking. As a result, the skin loses its elasticity and elasticity, the moisturizing effect is lowered, and skin symptoms such as wrinkles and sagging eventually develop.

Conventionally, as a method of coping with the reduction of skin firmness and moisturizing effect due to these external factors and aging changes, collagen and hyaluronic acid are blended into cosmetics and directly absorbed from the epidermis Alternatively, a nonpolar oil agent can be used to enhance the moisture retention ability of the skin by providing an emollient effect. However, these methods temporarily improve the moisture retention of the skin, but these components are physically attached to the epidermis and have a sufficient moisturizing effect even after rinsing or continuous use. I could n’t. Moreover, the moisturizing by the blending of the oil agent having an emollient effect was not sufficiently satisfactory in terms of use due to stickiness and the like.

For this reason, attempts have been made to improve the skin function by acting on the inside of the skin to increase the extracellular matrix such as collagen and hyaluronic acid. For example, as an attempt to improve the reduction of wrinkles and firmness of aging skin, an anti-aging cosmetic containing a chlorella extract, which is a collagen production promoter (see, for example, Patent Document 1), a loofah having hyaluronic acid production promoting action. Cosmetics containing seed extract (for example, see Patent Document 2), anti-aging skin external preparations containing synthetic peptides composed of 3 to 8 amino acids (for example, see Patent Document 3), etc. Has been proposed. However, although the techniques of Patent Documents 1 to 3 are effective for improving the production of collagen and hyaluronic acid, they are effective in improving certain wrinkles and elasticity, but are insufficient for the moisturizing effect and the durability thereof, and are sufficiently satisfied. It is not effective. On the other hand, as an attempt to improve the moisturizing effect, emulsified cosmetics containing ethyl oleate, a non-polar oil agent, a surfactant and water (for example, see Patent Document 4) have been proposed. However, although the technique of Patent Document 4 has a moisturizing effect, it is insufficient for the wrinkle improvement effect, and also causes stickiness and is not sufficient in terms of usability. In other words, the above-mentioned techniques are effective for either one of the moisturizing effect and the wrinkle improving effect, but the effect of satisfying both is insufficient, so that the sufficient anti-aging effect cannot be obtained, and the feeling of use is also sufficient. It is not satisfactory.
