As we age, our skin becomes less resilient as it produces less and less collagen and elastin. The result: the skin on our neck—which is already naturally thin— becomes thinner, less elastic and drier. This combination makes it appear less firm, saggy and wrinkled. Exposure to sunlight(ultraviolet light) causes the skin to age faster as our necks are exposed to the sun much more regularly than other parts of our bodies.
The tender skin of the neck is one of those areas most people easily neglect. For example, many people remember to moisturise their face, but it’s easy to forget about the neck. As a result, our necks often start to look much older than our faces.
Smoking can also contribute to fine lines and wrinkles developing in the neck area. Nicotine causes the blood vessels in the outermost layers of your skin to constrict— impairing blood flow and depriving the skin of oxygen and essential nutrients.
Because of looking down at our devices all the time(smartphone addiction), more and more young people are complaining of neck creases, popularly referred to as a “tech neck.”
