Abstract: The present invention relates to a composition for inhibiting erythema caused by ultraviolet radiation, wherein said composition contains a specific dipeptide, selected from 400 dipeptides, as an active ingredient. The composition of the present invention inhibit the production of prostaglandin E2(PEG2), thereby inhibiting erythema caused by ultraviolet radiation.

Abstract: The present invention relates to a method of preparing a collagen matrix with increased porosity and tensile strength by using mechanical stimulation system. More specifically, in the present invention, the cell-populated gel is being cultured under the condition that the physical forces is loaded for causing the matrix to move periodically and discontinuously. Resulting collagen matrix can be used for preparing an artificial skin or organs. Furthermore, this collagen matrix can be used as fillers for esthetic or therapeutic purposes.

Abstract: The present invention relates to a method for controlling elasticity of skin and compositions for the same, and more particularly, to a method for controlling elasticity of skin comprising the step of using a compound that inhibits or induces expression of tropoelastin mRNA or protein in keratinocytes. The present invention provides compositions for maintaining elasticity of skin by controlling tropoelastin mRNA or protein within human skin. The method for controlling elasticity of skin and compositions thereof regulates tropoelastin expression in keratinocytes, maintaining elasticity of skin and inhibiting production of elastotic material.
