There are two types of laxity: tissue and muscle laxity. Tissue laxity refers to the weakening of the collagen and elastin fibers that gives strength and support to skin tissue. The production of these proteins decreases naturally with age, but other factors can contribute to tissue laxity such as too much sun exposure, poor diet, smoking, pregnancy, substantial weight loss and hormonal disorders.
These same factors can also contribute to muscle laxity, but its main cause is sedentary life. The two types can appear together or separate. Laxity can occur on the body (arms, abdomen, legs and buttocks) as well as on the face, neck, and upper chest, contributing to wrinkles and expression lines. Currently, there are advanced technologies to treat tissue and muscle laxity.
Equipment stimulates the production of collagen and elastin, giving better support to skin tissue and improving skin laxity as well as promoting the contraction of muscle fibers and strengthening the musculature.
