A gradual depletion of collagen and elastin will make the skin more lax to appear loose. Sagging skin is apparent on the lower face, neck and on the body. Depending on the area, treatments can tighten the skin or restore volume to reduce visible laxity. Radiofrequency is a non-invasive treatment to heat the skin to 42 degrees to empty fat cells and tighten the skin on the face or body. Lasers can essentially vaporise excess skin and stimulate collagen and elastin production to also tighten skin. Injectables administering hyaluronic acid help to restore lost volume, causing the drop of skin, to pull the skin for a lifted and hydrated appearance.
