Why do some people’s skin look younger? A molecular study of women of various ages suggests its all in the genes.The gene expression patterns of skin biopsies from the subset of women who were younger-appearing were similar to those in women who were actually younger. While older appearing women had more of the molecular and genetic changes that can be attributed to chronic environmental stress such as ultra violet light. So protect your skin and pick your parents carefully!
