Most skin sagging is caused by long-term sun exposure.
Sagging skin is a problem that occurs over time. Sun damage destroys the healthy elastic fiber network in your skin that resembles a fishnet stocking. This network allows your skin to stretch and recoil back to its original shape. As this elastic fiber network gets digested along with the collagen that supports it, it is replaced with abnormal clumps of non-functioning elastic tissue. In addition, with age we lose volume in our face, which contributes to skin sagging as well.
UVA radiation significantly contributes to skin sagging, and UV-blocking window film will protect us from UVA in the car.
Longer wavelengths of sunlight, or infrared radiation also contributes to sagging skin – this is the heat from the sun that you feel when you’re outside or driving in a car.
In addition, we lose volume in our faces as we age. Muscles and fat tissue beneath the skin become thinner with age and contributes to sagging skin – not just in the face, but all over the body.
Before & After
Sagging skin is much more difficult to repair or improve than other signs of aging, such as fine lines and wrinkles.
The gold standard for improving sagging facial skin are surgical procedures such as facelift or neck lift. Surgery can tighten the deeper connective tissue beneath the skin to reduce sagging.
