A composition consisting of a combination of peptides that regenerate the dermal matrix and a rapid acting muscle relaxant derived from the extract of the plant, Acmella oleracea. By limiting cutaneous deformation caused by the contraction of facial muscles the extract increases the efficiency of the peptides in reducing expression lines.

The present invention relates to a production method for cryopreserved acellular dermal matrix and to cryopreserved acellular dermal matrix produced thereby, and more specifically it relates to a method in which a cryopreservation agent is made by adding sucrose to basic components consisting of glycerol and a basic solution and in which the resulting solution is used in the cryopreservation of skin tissue from which the cells in the epidermis and dermis have been removed, and relates to cryopreserved acellular dermal matrix produced thereby.

The invention relates to the field of gelatin-based biomedical materials, in particular to a preparation method and application of a bionic electronic skin medical stent with a self-repairing function. The method is characterized in that gelatin extracted from an acellular fetal calfskin dermal matrix with good biological safety is used as a raw material; then, conducting polymer poly (3, 4-ethylenedioxythiophene) with good biocompatibility is used; compounding a polystyrene sulfonate (PEDOT: PSS) solution with self-made acidified carbon nanotubes (H-MWCNTs); the hydrogel stent with a multifunctional three-dimensional network space structure is obtained through crosslinking of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC), and the hydrogel is good in biocompatibility and high in mechanical strength, has both self-repairing performance and tissue regeneration inducing repairing performance and can be widely applied to skin wound repairing treatment.
