We also use dermal fillers at Bayside Family Medical & Musculoskeletal Practice. These are made up of gels that can help fill your deep creases for a smoother appearance. The filler used is a substance found naturally in the body, and over time the dermal filler breaks down via normal body processes. Dermal fillers are a popular choice because they allow greater precision in wrinkle correction and can treat medium to deep wrinkles effectively. They also do not cause any loss of ability to contract your facial muscles.
