Skin augmentation with collagen, hyaluronic acids, and other materials can improve one’s appearance by filling rather than stretching the skin. As we all grow older, all tissues whether skin, bone, or muscle will tend to become less bulky. The skin becomes less well filled, and tends to develop wrinkles and folds of excess. Some times a lifting procedure is appropriate, but oftentimes use of a filler agent will literally fill out the sagging skin. It’s like a balloon that is loosing air; to make it taught again, one has to blow it up again!
