Beneath the skin of our face, there are fat pads that act like cushions, plumping the skin. When you lose weight quickly, the volume of these cushions decreases sharply. Because the skin cannot shrink at the same pace, the excess skin sags, like a deflated balloon. (Recently, the term "Ozempic face" has even been coined to describe the phenomenon of the face aging after short-term weight loss, fueled by the popularity of obesity treatments.)
When this is combined with the natural decline in collagen, which decreases by about 1% each year starting in the mid-20s, and bone resorption, where the facial bones themselves lose volume with age, the bone, fat, and collagen collapse in a triple manner, making the face appear more hollow and aged.
