Although menopause isn’t diagnosed as a condition until a full year after your last period, changes to your skin can start five to six years beforehand. Collagen is one of the most abundant proteins in our bodies. It strengthens the bones and gives elasticity to skin and tendons. As menopause approaches, we begin producing not only less estrogen but also less collagen. This leads to dry, thin, or sagging skin, wrinkles, and enlarged pores.
