Within the connective tissue of the dermis, collagen and elastin fibers form a network that provides the skin with structure, support and elasticity. Furthermore, fat cells and other molecules, such as hyaluronic acid, help to create volume beneath facial skin. With time, this network of collagen and elastin fibers breaks down, and hyaluronic acid molecules and fat cells that create volume are depleted. Together, breakdown and depletion of these molecules result in wrinkles and other changes to facial skin.
When used as standalone treatments or with other procedures, injectable fillers can reduce or eliminate wrinkles and scars, create fuller lips, and treat lipoatrophy, or fat loss beneath the skin. With little downtime and almost immediate results, injectable fillers offer a safe, effective method of restoring a smoother, more youthful appearance..
