Information And Treatment
Ah, forehead wrinkles. Their very designation as "frown lines" is misleading, since they actually form vertically between the eyebrows and across the forehead. While it's commonly assumed that wrinkles are primarily stress-induced (explaining the aforementioned misnomer), these features are in fact the combined product of not only anxiety but, more likely, sun exposure and muscle movement.
Wrinkling is caused by the lack of collagen, the protein that makes up 80% of the skin and accounts for its ability to stay hydrated and elastic. As collagen is damaged by the sun and by aging, your skin is left thinner, weaker, and less capable of returning to a smooth, taut state after contorting your forehead. Wrinkles will appear whenever muscles move in your forehead - for example, when you squint. Worse yet, the wrinkles will eventually just settle in permanently, appearing even when you're relaxed.
Age range: Take a look in the mirror (We'll wait.) Do you have wrinkles on your forehead? The aging process is highly variable and, depending on genetics and how you've treated your skin through the years, can begin as early as 20 or as late as 40 (lucky you!)
Why does stress cause wrinkles? Chronic stress damages the inner lining of the arteries, causing them to compress. Wrinkles are created when these vessels shrink permanently.
