Skin looseness is a problem that troubles a large percentage of men and women. Many confuse muscular with skin looseness and turn to gyms, believing that by strengthening the muscles they will also restore skin looseness. The skin is not composed of muscles but of collagen and elastin fibers, that keep it firm and young. With the passage of time or with the change in weight, these fibers stretch and their elasticity is reduced, resulting in skin looseness.
