What should I do about sagging and loose skin?

Skin sagging and laxity are natural signs of aging, but can be improved through various methods. 1. Maintaining a healthy lifestyle—including a balanced diet, regular exercise, and sufficient sleep—is fundamental to preventing skin laxity. 2. Using skincare products containing collagen and vitamin C, along with regular facial massage and dermatologist-recommended lifting and firming treatments, can also effectively improve skin sagging.
