Collagen is a protein found in cow-derived products or in human skin, and is commonly used to plump up the lips. It can also be used to counteract the look of mild to moderate creases in the face. It’s a popular dermal filler option for patients who are maintaining their appearance after a facelift or other facial plastic surgeries. Patients who are using cow-derived collagen (bovine collagen) will need to undergo pre-treatment allergy testing.
Hyaluronic Acid Hyaluronic acid is a naturally occurring substance found in human connective tissues and around the eyes. When used as a cosmetic injectable, hyaluronic acid acts as a cushion that inflates the tissues, while simultaneously drawing water to the surface of the skin. It can be used in the cheek areas to replace lost fat and can also be used to fill in lines, wrinkles and folds.
