What causes Skin Laxity?
Skin laxity, a loss of dermal collagen content, is due to intrinsic and extrinsic factors, with smoking and ultraviolet radiation (UVR) the most common extrinsic factor. Approximately 1% of an adult’s skin dermal collagen content is lost each year causing the sagging and crapey skin appearance. In order to improve the loss of collagen, one needs to stimulate or encourage the formation of new collagen in the affected areas. Common areas that are treated for skin laxity include the face, neck, back of arms knees, stomach, and back.
