Sagging Skin

This is often referred to as sagging or drooping or thinning of the skin. Droopy jowls, crepey skin on the back of the hands, loose saggy skin on the elbows, arms, thighs, and knees are generally thought of in this category.

The visible outer layer on the skin surface called the epidermis acts as a protective barrier. Underneath that is the elastin and collagen-rich tissue called the dermis. The subcutaneous layer below that is the fat layer, with a web of collagen fibers running through it.
