Apart from wrinkles, a loss of elasticity is another sign of ageing skin. With age, your skin looses its tautness and becomes loose. With ageing, the combined effects of our genetics, sun damage and lifestyle choices affect the elasticity of our skin. Skin sags primarily due to the loss of volume and also because of a decrease in collagen and elastin. Collagen and elastin are the building blocks of the skin and the absence of these prevents the skin from going back to its original shape after stretching or contracting. The face for instance, will appear sunken and less full around the eyes and cheeks. Hanging skin around the jowl and neck, as well as an increased looseness around the nose and corners of the mouth are typical in ageing skin. With the right laser, these effects can be largely reversed.
