Toxins, like chemicals from pollution and smoking, can prematurely age your skin. They may contribute to wrinkles, age spots, and uneven color. For example, people who smoke often discover that the chemicals in cigarettes damage the skin's elasticity, leading to sagging or wrinkles.

Skin care is the range of practices that support skin integrity, enhance its appearance and relieve skin conditions. They can include nutrition, avoidance of excessive sun exposure and appropriate use of emollients.
