The substances or toxins you take in affect every organ of your body, including your skin.
According to a 2021 review Trusted Source, caffeine, nicotine, and alcohol can cause collagen and elastin fibers in skin to break down. Collagen is an essential protein that affects the health and function of the dermis.
When collagen and elastin levels decrease, skin is more likely to sag, wrinkle, and lose firmness.
Caffeine, nicotine, and alcohol may also reduce moisture in your skin, which could cause wrinkles to develop more easily or be more visible.
In general, wrinkles brought on by normal aging tend to appear later in life than wrinkles brought on by caffeine, nicotine, and alcohol. The association between prominent aging and caffeine, nicotine, and alcohol seems to be especially apparent when people consume them.
