Lower lid skin laxity is caused by the loss of collagen from the skin under the eyes, which is mainly caused by prolonged late nights, irregular lifestyle, and prolonged exposure to radiation from computers and cell phones. Therefore, to improve the laxity of the lower eyelid skin, you need to first avoid staying up late for a long time, and then avoid radiation and long-term exposure to UV rays. Take more collagen and vitamin-rich foods. Don’t rub your eyes too hard, and you need to hydrate your skin every day; no other treatment is usually required. However, as the skin ages and its elasticity decreases, some people who are concerned about their appearance may request surgery. Surgery for lower lid skin laxity mostly involves removing excess fatty tissue and skin to achieve a tighter look. However, fewer middle-aged and older people request this surgery, unless the laxity of the eyelid is so severe that it is blocking their vision and affecting their lives.
