Hyaluronic acid is a natural substance normally found in the skin, joints and eyes. Hyaluronic acid may be applied topically to the skin with a needle or by injection into the deep dermis or under the skin.
Injection is performed using a 25- or 30-gauge needle. Cannulas may be used for general placement of hyaluronic acid; however, needles are preferred when accurate placement of hyaluronic acid is needed. A topical anesthetic may be required.
Hyaluronic acid is used to improve mild to moderate folds and wrinkles. Hyaluronic acid may be used anywhere on the face, including the lips, nose, and around the mouth.
Hyaluronic acid may be placed in the dermis or above the bone. When injected too close to the surface, hyaluronic acid can be seen through the skin and has a blue appearance.
When injecting hyaluronic acid, vascular injury due to occlusion or compression should be avoided.
