Eye bags, also known as lid bags, are mostly caused by ageing, skin relaxation around the eyes, weakening of the orbicularis muscle, and bulging of the orbital fat, and a small number of young people can also cause eye bags due to long-term sleepless nights. For light bags, there is usually no adverse effect on the health of the body and no special treatment is needed, but the bags may affect the aesthetics and can be improved by physical and non-invasive treatment; for middle-aged and elderly people and those with severe bags, surgery is recommended when necessary. For mild under-eye bags and young patients, under-eye bags can be improved by physical treatments such as laser and radiofrequency. Laser or radiofrequency can shrink the soft tissue of periorbital skin to lift and tighten the skin and deep fascia around the eyes, and can also assist in daily massage of skin around the eyes and use eye patch for hydration. For mild under-eye bags with less fat bulge, young people with better skin elasticity and more collagen, non-invasive photoelectric or radiofrequency treatment is more effective. In middle-aged and elderly patients or patients with severe under-eye bags, because their skin is gradually relaxed, elastic fibers and collagen loss, if not treated in time, with the development of under-eye bags, fat herniation increases, causing impact on appearance, at this time, surgery is needed to remove the lower lid orbital fat and strengthen the structure around the eyes. A four-step orbital bag surgery is often used, which mainly includes removing part of the orbital fat, reinforcing the muscle structure around the eyes, suspending the lateral ligament, and removing excess skin tissue.
