Effects of arginine glutamate (RE:pair) on wound healing and skin elasticity improvement after CO 2 laser irradiation.

RE:pair shows a greater therapeutic effect than the individual effects of its constituent amino acids and those of the simple mixtures of these compounds. RE:pair exerts its therapeutic action by promoting the proliferation of keratinocytes and enhancing collagen synthesis in fibroblasts. Accordingly, it can be used throughout the cosmetic industry as an effective amino acid wound healing and skin elasticity improving material.
