The effects of aging take their own toll on the skin, but they're exacerbated by many environmental factors, including smoking. One of the most important preventative skin care tips is to refrain from smoking. Common smoking behaviors, such as puckering the lips and squinting, can cause lines to form around the mouth and eyes. In addition to causing wrinkles, smoking can also produce an unsightly, sallow skin tone, as it restricts blood flow. If you're a smoker, quitting now and following dermatologist-recommended skin care tips can help prevent nicotine's acceleration of skin aging.
