Knowing what you may look like as you age if you smoke or spend a lot of time in the sun might encourage you to adopt healthy habits while you can. The rate at which skin ages depends on many factors, including genetics, diet, hormonal factors, and lifestyle factors like tobacco smoking and exposure to environmental chemicals and the sun's radiation. While fast-forwarding the aging process can be a fun (or frightening) party game, there’s research that seeing your future self this way can help jumpstart healthy behaviors (like quitting smoking) in the present.

There are online sites, software, and apps for your smartphone that can show you what you may look like as you age.
Photoaging from sun exposure is caused by the sun's UVA and UVB rays. Staying out the sun can help reduce these aging effects and sunscreen may also help prevent the damage. The UVA rays penetrate to the lower layers of the skin and damage the collagen. This leads to fine lines, wrinkles, and age spots. UVB rays cause sunburn, which damages the skin as well.
Premature wrinkling was first documented in smokers in the early 1970s. Chemicals in tobacco smoke damage collagen and elastin in the skin, leading to premature sagging and wrinkles. Nicotine also narrows the blood vessels in your skin so it receives fewer nutrients. Smoking continues to be found by 2017 research to be a major contributing factor in facial wrinkling
