Abstract: Provided is a cosmetic composition for skin protection containing Phaseolus radiatus extract of fermentation-enzyme treatment, prepared by fermenting Phaseolus radiatus with Saccharomyces cerevisiae or Lactobacillus and treating thereof with protease as an active ingredient, and a make-up method using the same. The Phaseolus radiatus extract of fermentation-enzyme treatment of the present invention contains higher isoflavone and has activities of increasing skin cell activity, alleviating skin irritation, and accelerating synthesis of skin cell protein such as collagen, so that it brings the effect of improving skin troubles caused by aging and protecting skin as well.

Abstract: The present invention relates to cosmetic compositions and more particularly to skin-whitening cosmetic compositions comprising senkyunolide A as an active ingredient. The present invention discloses the novel inhibitory function of senkyunolide A isolated from Cnidium officinale and Ligusticum chuanxiong on the melanocyte-stimulating hormone (MSH), and provides MSH-inhibitory compositions and skin-whitening cosmetic compositions comprising the senkyunolide A. The compositions of the present invention show significantly enhanced skin-whitening effect owing to its efficient inhibition of MSH even in lower concentration.

Abstract: The present invention relates to a pseudoceramide represented by the following formula (I) and a cosmetic composition comprising the same: wherein Z represents —OH and Y represents —OH, ?with the proviso that X is Z represents —OH and X represents —OH, with the proviso that Y is Y represents —OH and X represents —OH, with the proviso that Z is R represents a linear or branched, saturated or unsaturated aliphatic hydrocarbon group; and when substituted, R has one or more —OH groups.

Abstract: The present invention relates to a novel retinol derivative and a cosmetic composition comprising the same, in particular, to a novel retinol derivative represented by the formula (I) exhibiting the effects from both L-ascorbic acid and retinol as well as being free from the disadvantages of two compounds such as skin irritation and instability in cosmetic formulation, and a cosmetic composition comprising the retinol derivative.

Abstract: The present invention relates to a phytandiol amine derivative represented by the following formula (I) and compositions for treating acne comprising the same: wherein each of Y and Z is OH with the proviso that X is NH2, each of X and Z is zOH with the proviso that Y is NH2, and each of X and Y is OH with the proviso that Z is NH2.

Abstract: The present invention concerns stabilized cosmetic material containing triple-encapsulated retinol. Unstable, fat-soluble retinol is stabilized firstly by addition into vesicles consisting of nonionic surface-active agent, cholesterol and cholesteryl ester. The firstly stabilized retinol(vesicle) is subsequently inserted into sphingosomes (a kind of multi lamellar liposome) consisting of lecithin and ceramide. Finally the double-encapsulated retinol (sphingosome) is inserted into lamellar liquid-crystal emulsifying base, thereby being triply encapsulated.

Abstract: A cosmetic composition for skin care containing retinol and epidermal growth factor is disclosed. In embodiments of the cosmetic composition, the epidermal growth factor is preferably present in an amount of 0.00001 to 1% by weight, and more preferably 0.0001 to 0.1% by weight, based on the total weight of the composition. The EGF-containing cosmetic composition of the present invention enhances the skin care effect of retinol and also alleviates adverse effects of retinol, such as skin irritation.

Abstract: Disclosed are chitosan derivatives and a preparation method thereof, in which a chitosan is combined with a polypropylene glycol that provides a required solubility in water and high compatibility with other compounds. The chitosan derivatives represented by the formula I are prepared by grafting the polypropylene glycol on the amino group or hydroxyl group of the chitosan or a partially deacetylated chitosan by nucleophilic substitution: wherein Rchit represents a chitosan or a partially deacetylated chitosan; and n is an integer.
