Tip: Don't smoke
Smoking accelerates aging of your skin and increases wrinkles. Skin changes from smoking can appear in young adults after 10 years of smoking.
Smoking causes narrowing of the tiny blood vessels in the outermost layers of skin. This decreases blood flow, depleting the skin of oxygen and nutrients, such as vitamin A, that are important to skin health. All of these factors increase damage to the elastic fibers (elastin) and collagen, which give your skin strength and elasticity.
In addition, the repetitive facial expressions you make when smoking — such as pursing your lips when inhaling and squinting your eyes to keep out smoke — may contribute to wrinkles. It's also possible that repeated exposure to the heat from burning cigarettes may damage your facial skin over time.
