Abstract: The present invention relates to a method for concealing wrinkles. The method for concealing wrinkles includes applying a cosmetic composition having an oil-wax gel for diffusing reflection of light at a wrinkled area to a skin, wherein the oil-wax gel is a gel comprising silicone oil and wax, wherein hardness of the oil-wax gel is 100 to 4000 dyn/cm2, and wherein the oil-wax gel comprises 5 to 95 parts by weight of the silicone oil relative to 100 parts by weight of the oil-wax gel and 1 to 50 parts by weight of the wax relative to 100 parts by weight of the oil-wax gel.

Abstract: The present invention relates to an ultraviolet protection factor calculating apparatus and an ultraviolet protection factor calculating method for calculating an ultraviolet protection factor according to information of a cosmetic without a measurement experiment. The method may comprise the steps of: storing a database including a plurality of cosmetics and ultraviolet protection factors corresponding to the plurality of cosmetics, respectively; on the basis of the database, generating a decision tree in which the cosmetic ingredients included in the plurality of cosmetics are explanatory variables and an ultraviolet protection factor is a dependent variable; receiving an input of information of a cosmetic; and outputting the ultraviolet protection factor of the cosmetic, the information of which has been input, according to the decision tree.

Abstract: Provided is a method for improving fragrance persistence by applying a composition including, as active ingredients: oil; and non-ionic polymers having hydrophobic substituents at both termini thereof. In the composition of the presently claimed subject matter, the non-ionic polymers having hydrophobic substituents at both termini thereof form a flower micelle structure by capturing oil and a fragrance through the hydrophobic substituents, and thus can stably maintain the oil and fragrance and prevent fast volatilization of the fragrance, thereby improving fragrance persistence.

Abstract: The present invention relates to a cosmetic composition for concealing wrinkles. The cosmetic composition according to the present invention causes diffuse reflection of light on a wrinkled spot without using powder and effectively fills the wrinkled spot of skin, thereby enabling a temporary concealing of the wrinkle. Because powder is not used, the cosmetic composition has an excellent feeling of use when applied to the skin and prolonged adhesion to the skin, with no white turbidity.

Abstract: The present invention relates to a translucent or semi-translucent nano-emulsion cosmetic composition, having excellent stability, comprising high content oils (5 to 30%) and, more specifically, to a nano-emulsion cosmetic composition having a physical property of low viscosity (5000 cps or less) with a translucent or semi-translucent appearance by preparing pre-emulsion by applying an emulsifier and then secondly passing the pre-emulsion through a high pressure homogenizer, and a method for preparing the same.

Abstract: The present disclosure relates to a system for administering retinol into skin that ensures stability of retinol, reduces skin irritation of retinol, and continues to exert effects, wherein the system is a microneedle including microparticles containing retinol or retinol derivatives. The present disclosure further provides a method for manufacturing a retinol administration system that reduces skin irritation, exerts effects of retinol for a long time, and ensures stability of retinol very unstable to light, wet and temperature. The present disclosure further provides a method for administering retinol into skin using the microneedle.

Abstract: The present invention relates to a fusion peptide, in which a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human Type-I collagen C-terminal derived peptide, a preparation thereof, and a skin anti-aging cosmetic composition comprising the same. Since the fusion peptide, in which the Tat peptide is bound to the human Type-collagen C-terminal derived peptide is highly stable and has a superior skin absorption capability, the present invention provides a skin anti-aging agent having superior synthesis of collagen and hyaluronic acid, anti-aging effects, and improved durability of the effects.

Abstract: The present invention relates to a fusion peptide wherein a self cell-penetrating Tat peptide having a self penetrating signal is bound to a human parathyroid hormone-derived peptide, a preparation thereof, and a skin slimming cosmetic composition comprising the same. Since the fusion peptide wherein the Tat peptide is bound to the human parathyroid hormone-derived peptide has high stability and superior skin absorption, the present invention provides a skin slimming agent having superior lipolysis effects and improved durability of the effects.
