Collagen injections have been used for decades to treat minor imperfections in facial skin, including laugh lines, wrinkles, creases, crow's feet, and acne scars. Collagen is also used to create fuller lips and cheeks and can also be used to treat areas of the chest, back, and neck.
Collagen is a natural protein found in the body. Certain collagens in skin tissue are essential for skin strength and elasticity. Over time, this collagen breaks down, causing skin to lose it's suppleness and begin to wrinkle and sag. In an effort to fight these signs of aging, many people turn to collagen injections to replace their original supply. Since it is a natural protein, there are relatively few side effects associated with its use in cosmetic procedures.
Collagen treatment involves one or more injections of collagen into a specific area. Some patients experience slight discomfort with the injection, especially those performed on the lips or around the nose. A topical anesthetic can be applied to the injection area to minimize pain. Some types of collagen contain a small amount of lidocaine, which also helps to numb the injection area. Most treatments take less than an hour and can be accomplished during a lunch break.
