Natural ageing is the number one factor towards loose facial skin. As a person ages, their skin’s collagen and elastin production slows down, and this is exacerbated by muscles that start to weaken over time. Both of these things can reduce the elasticity of the skin and increase the chance of sagging as a result of gravity.
Loose facial skin may also be experienced if you’ve experienced significant weight loss within a short period of time. When a lot of weight is suddenly lost, this can cause the skin to loosen and sag.
Finally, loose facial skin can also be caused by excessive sun exposure. Getting too many UV rays can lead to cell death, which negatively impacts elasticity and collagen production.
