What are the long-term side effects of fillers?

These side effects can have undesirable consequences when swallowing, with vocal cord function and eye movements, including double vision. There is a misconception that temporary fillers rarely cause side effects; the frequency is comparable to that induced by permanent and long-lasting fillers, but their duration is shorter and therefore less severe.

However, recent studies indicate that repeated and prolonged use of deep tissue facial fillers can cause permanent damage or damage to the lymphatic system of the face.
