Neck lines or neck wrinkles are like any other wrinkles you may see around your mouth , eyes hand, forehead . Even though wrinkles are a natural part of aging certain factors like smoking or prolonged expose to ultra violet rays can make them worse.
The extent of your neck lines and other signs of aging are determined partly by genetics.
Causes
Neck lines or wrinkles are caused by a combination of natural aging and daily activities we engaged in. All wrinkles are caused in part by repeated movements. The more we engaged in activities that lead to the folding of the skin, the earlier lines and wrinkles will start to set in.
