Description

The present invention relates to a skin cosmetology method. The present invention also relates to an external composition for skin used in the cosmetological method.

Many people, especially women, have a desire to have beautiful skin no matter how old they are, and several products and methods have been proposed to fulfill this desire. In particular, with aging, many undesired symptoms such as wrinkles, sagging, age spots, and freckles appear, and products and methods for preventing or ameliorating these symptoms are required. In addition to aging, the skin deteriorates due to dietary and lifestyle disorders, lack of sleep, stress, etc., and the smoothness (smoothness), softness, firmness, etc. decrease, and even if makeup is applied. There is a problem that the makeup is bad. For this reason, regardless of age, we want to maintain or improve the smoothness (smoothness), firmness (elasticity and hardness of the skin), plumpness (softness and stickiness of the skin), glossiness, and moisturizing feeling. The demand is deep-rooted.
