BIOMECHANICAL STIMULATION OF COLLAGEN SYNTHESIS IN SKIN CELLS AND REDUCTION OF SKIN SMALL LINES AND WRINKLES Russian patent published in 2014 - IPC A61K8/64 A61K8/67 A61K8/899 A61K8/72 A61Q19/08 

FIELD: medicine.

SUBSTANCE: invention represents a method for biomechanical stimulation of collagen synthesis in skin cells and reduction of skin small lines and wrinkles involving: (a) forming a polymer composition containing a first polymer and a second polymer that are dissolved or dispersed in a solvent system containing water, wherein the above first polymer represents a water-soluble or water-dispersible anionic polymer able to be reduced after solvent evaporation, and wherein the above second polymer represents a water-soluble or water-dispersible cationic polymer able to form a polymer complex able to bind to a skin surface, (b) applying the polymer composition on a first skin region and a second skin region, wherein the first and second regions are separated from each other at a specified distance by at least one small line or wrinkle in between; and (c) drying the polymer composition in the first and second skin regions in the first and second skin regions so that water evaporates in the solvent system and the polymer composition is initiated to be reduced in the first and second skin regions, wherein the above reduction creates a tension over the skin surface between the first and second regions; the tension provides the biomechanical stimulation of collagen in skin cells and reduction of skin small lines and wrinkles.

EFFECT: invention provides the biomechanical stimulation of collagen in skin cells and reduction of skin small lines and wrinkles.
