GlossaryReconstructed Human Epidermis

laboratory-grown model of human skin for research and testing

Reconstructed Human Epidermis (RHE) is a laboratory-grown model of human skin created from cultured human skin cells. It mimics the structure and function of the outermost layer of the skin, making it a valuable tool for testing cosmetics, pharmaceuticals, and studying skin biology without the need for animal testing.
