  • the subject to which the cosmetic according to this embodiment is applied is mainly the face, but it may also be applied to parts other than the face, such as the Vietnameselleté (neck, shoulders, and chest) and the back.
  • the two-component type refers to a form in which at least two compositions are mixed immediately before application to the skin. Therefore, the skin-improving cosmetic according to this embodiment is provided in a state in which the first part (first composition) and the second part (second composition) do not come into contact with each other.
  • the first part and the second part may be contained in separate containers, or the first part and the second part may be contained in one container having a plurality of chambers separated by partition walls. They may be housed in different chambers.
  • the two-component skin-improving cosmetic composition of the present embodiment may contain an additional part having a composition different from that of the first part and second part.
  • the properties of the cosmetic according to the present embodiment are not particularly limited, but when the mixture obtained by mixing the first part and the second part is applied to the surface of the skin, it forms a film with a certain thickness on the skin.
  • the cosmetic according to the present embodiment has properties called gel (gel), cream, base, or balm immediately before being applied to the skin.
  • the skin-improving cosmetic in which Part 1 and Part 2 are mixed contains carboxyvinyl polymer, sodium silicate, glycylglycine, and water.
  • a combination of these ingredients can provide a cosmetic that exhibits a wide range of skin-improving effects.
  • the skin-improving action of the skin-improving cosmetic is immediate (that is, it can be effective even after one use), and the action continues even after the cosmetic is washed off. More specifically, according to the present embodiment, it is possible to provide a cosmetic that exhibits an excellent wrinkle-improving effect and/or pore-improving effect that is fast-acting and highly durable.
  • the wrinkle-improving action refers to reducing the depth of wrinkles (groove-shaped depressions formed on the surface of the skin), reducing the width, or shortening the length, or wrinkles. It refers to the action of smoothing the surface of the skin.
  • the pore-improving action refers to reducing the depth of pores, reducing the diameter of pores, or reducing the number of pores.
  • the wrinkle-improving action is also closely related to the sagging-improving action and the like. When the wrinkle-improving action is enhanced, sagging of the skin is also reduced or eliminated, and the skin can be made firmer. The action of reducing wrinkles and sagging and providing firmness is sometimes called a lift-up action. According to this form, immediate or immediate skin improvement effect can be obtained without surgically invasive treatment, and the effect is sustained for a long period of time.
