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 compositions for inhibiting elastase activity, enhancing collagen biosynthesis and improving skin wrinkle, comprising Mallotus japonicus extract as active ingredient. The present compositions exhibit the inhibition effect on elastase activity and promotion effect on collagen biosynthesis at a molecular level, and as a result, excellent efficacy in improvement of skin wrinkles.

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: Disclosed is a method for preparing an aqueous phytosphingosine solution containing as much as 5-10 weight % of phytosphingosine without using any solvents other than water. A high content of phytosphingosine is dissolved in water and lactic acid with the help of a willow bark extract. In addition to being clear, the aqueous phytosphingosine solution is able to recover damaged skin with activity against bacteria and inflammation. Also, when being applied for cosmetics, the aqueous phytosphingosine solution allows them to contain as much as 1-2 weight % of phytosphingosine by virtue of its high content of phytosphingosine. Further, the phytosphingosine solution is greatly improved in compatibility with cosmetic components so that it can be readily applied for aqueous cosmetics such as skin lotions, essence lotions, aqueous pack products, body essence compositions, etc., for which phytosphingosine has not yet been applied, thus far.

Abstract: Disclosed are compositions for skin care and their medicinal uses. The compositions are identical in lipid constituents and structural properties to that of human stratum corneum. They comprise the major constituents for the lipid lamellar of the stratum corneum, including ceramides, cholesterol and fatty acids, the major constituents for epidermal cell membranes, including phospholipids, and physiologically active substances, including phytosphingosine and its derivatives. Without causing side effects, the cream composition for skin care is of much better skin penetration and water-retention capacity than are conventional compositions comprised of ceramide and other components in forms different from those of human skin. In addition to providing inhibitory activity against skin microorganisms, the cream composition brings about an improvement in the wrinkle condition of the skin, so that it can be applied to cosmetics.
