WHAT ARE THE CAUSES ?
The skin laxity that appears with age is one of the causes of the sagging of the face and the appearance of the heaviness of the eyelids' skin.
We are all born with different genes. The genetic background that our parents passed on to us may be responsible for the premature loss of eyelid firmness in some people.
Sun exposure, smoking, and environmental pollution, especially in large cities, can play a role in the premature loss of skin firmness, especially of the eyelids.
A large and rapid weight loss can be responsible for a decrease in the face firmness, which can affect the eyelids' tone and cause them to be heavy.
