Definition of Hyperelastic skin:

Hyperelastic skin is skin that can be stretched beyond what's considered normal, and then returns to normal.

Considerations:

Hyperelasticity occurs when there is a problem with the production of collagen fibers. Collagen is a type of protein that makes up much of the body's tissue.

Common Causes:

Hyperelastic skin is most often seen in the Ehlers-Danlos syndrome. People with this disorder are sometimes referred to as rubber men (or women) because of the increased elasticity of their skin and hyperextensible joints (the joints can be bent more than is normally possible).

Other diseases that may cause easily stretchable skin include Marfan syndrome, pseudoxanthoma elasticum, osteogenesis imperfecta, cutis laxa, cutaneous T-cell lymphoma, and sun-related changes of older skin.
