BelleMag feels all your needs > Does lack of sleep really cause wrinkles?

Yes, a lack of sleep causes wrinkles and promotes the aging process of the skin. Due to lack of sleep, the body secretes too much cortisol, the stress hormone. As a result, the formation of hyaluronic acid is reduced, thus losing the necessary hydration to the skin which damages its protective barrier function. By sleeping less, the body also secretes less melatonin, the sleep hormone. In sufficient quantity, it protects against cell damage, helps skin regenerate and promotes collagen synthesis. In conclusion? Eat well, sleep well and your skin will say thanks!
