What are the causes of acquired cutis laxa?
Disease description:
I am a 40-year-old woman who recently noticed that my facial skin has become loose, especially in the cheeks and neck areas, making me look older than others my age. I heard this might be acquired cutis laxa, but I am unsure of the exact cause. Could you please explain what causes acquired cutis laxa?

Acquired cutis laxa is primarily caused by a reduction or damage to collagen and elastic fibers in the skin. As people age, the body's natural ability to synthesize collagen and elastic fibers gradually declines, which is a major cause of skin laxity. In addition, prolonged exposure to ultraviolet radiation can damage collagen and elastic fibers in the skin, accelerating skin aging. Unhealthy lifestyle habits, such as smoking, alcohol consumption, and irregular作息 (作息 should be translated as "作息" is not properly converted here, please clarify), can also damage the skin and lead to skin laxity. Environmental factors such as air pollution and dryness can negatively affect the skin and further exacerbate skin laxity.
The following measures are recommended to prevent and improve acquired skin laxity. Maintain good lifestyle habits, including adequate sleep, balanced diet, and moderate exercise, all of which help enhance the body's repair capabilities and promote skin health. Avoid prolonged sun exposure; apply high SPF sunscreen, wear a hat, or use an umbrella when outdoors to protect the skin from UV damage. Quit smoking and limit alcohol consumption to reduce skin irritation. Use skincare products containing antioxidants such as vitamin C, vitamin E, and retinol, which can help protect the skin and promote collagen production. If skin laxity is severe, consider medical aesthetic treatments such as radiofrequency skin tightening, ultrasound therapy, or thread lifting, which can help improve the condition to some extent.
