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.

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.

People with hyperelastic skin are more likely than others to experience damage to the skin (cuts, scrapes, and scarring). The skin may be more delicate than normal skin. Extra care must be taken to avoid damage to the skin, and the skin should be examined frequently for problems.
