What are these?
Restylane, Juvederm, Perlane, and Belotero are all sterile gels consisting of stabilized hyaluronic acid used to treat facial wrinkles and lines as well as lips for augmentation. All have been approved by the FDA for correction of facial wrinkles in the nasolobial area (“on-label” use), the fold between the cheek and the nose/upper lip.
What are the side effects and risks?
Side effects include but are not limited to: potential allergic reaction or injection site reactions (a lumpy or “thick” feeling at or just under the skin, bruising, redness, itching, pain, tenderness, or slight swelling). Injections into the lip area could trigger a recurrence of facial cold sores (Herpes simplex infections) for patients with a history of prior cold sores.
