As we age, and spend more time in the sun, our skin becomes weaker and less elastic. Collagen, the protein that makes up 80% of our skin, loses its ability to stretch and recoil and we develop wrinkles and age (liver) spots that make us look much older than we are. It is, however, possible to turn back the clocks and regain much of your skin’s youthful glow and fresh appearance, and to continue to look after yourself in the longer term.
