As we age, the underlying tissue structure and muscles supporting the eyelids weaken. As the skin sags, the fat pads under the eyes push forward. Fluid can also pool under the eye, causing it to look puffy and swollen.
In the mid-cheek, the fat pads start to shrink and descend, and this can result in a deepening groove at the junction between the under eye and upper cheek, whereas previously it was smooth. This is known as the tear trough.
Certain lifestyle factors can exacerbate these ageing changes, such as sun damage, which accelerates collagen and elastin breakdown or alcohol consumption that dehydrates the delicate tissues below the eye.
Lower eyelid blepharoplasty aims to improve the appearance of the under-eye area, making you look younger and more vibrant.
