What causes them: Sagging skin is caused by a loss of collagen and elastic tissue," Kauvar says. "These proteins give the skin strength and structure, and their amount decreases with age. Sun exposure also contributes."
How to prevent them: Kauvar says regular use of sunscreen and moisturizers with collagen-boosting ingredients can help prevent wrinkles, but not necessarily fix ones that are already there. (One to try: Clarins Advanced Extra-Firming Neck Cream, $59.99.)
How to treat them: "Laser and light procedures like Titan, Thermage and fractional CO2 lasers can help reduce early neck wrinkles, but surgery is the only option when the skin becomes excessively loose," Kauvar says. "Botox or Dysport injections can help smooth crepey neck skin."
