My friend recently told me dermal fillers on cheeks caused blindness and confused me. What are the side effects and results of filler treatment?

Dermal fillers are injectable hyaluronic acid solutions used to change the contour of face. Most common side effect is temporary bruising and swelling that subside within a few days. Infections at the injection site are rare provided proper hygiene was maintained during the procedure. Allergic reactions to filler substances are uncommon. A very rare side effect is inadvertent injection into a blood vessel causing tissue damage e.g. blindness. However, experienced and knowledgeable injectors almost never face this. Results of fillers are cosmetic enhancements. They can add volume to specific facial areas, such as the cheeks, smooth out wrinkles and lines, enhance the jawline, restructure the face etc by providing support to the skin and muscles. Results vary according to individual anatomy and the type of filler used. Please consult an experienced dermatologist to know the details of filler treatment and how it can help your specific case.
