Cosmetic fillers have been used for many years and are generally well tolerated. While you may experience no side effects at all, as with all medications, side effects can occur. Reported side effects are usually minimal and confined to the injection site. They include swelling, tenderness, redness, bruising, itching or discolouration. In the majority of cases, these are temporary and will usually resolve themselves. We offer to all clients, at a nominal rate, the use of the Omnilux Revive red light immediately post-treatment to help minimize these possible side effects.
