Funt & Pavicic (2013) suggested that Injecting excessive amounts of filler may interfere with the inner layers of the skin, causing the lips to become plumper and lose shape dramatically. Unqualified cosmetic doctors may fail to inform the patient about the effects of too much filler. They may also inject the lips inaccurately by infusing equal amounts of the filler instead of adhering to the natural lip outline.

Duck lips can also be caused by swelling and inflammation. These are common side effects that occur after lip filler injections. They usually subside with time, although they may also cause duck lips. If the swelling persists, it’s important to visit your doctor since the procedure is easily reversible.

However, self-injections are dangerous since most individuals are unfamiliar with the anatomy of the lips. Some lip fillers sold online might be unregulated and contain harmful ingredients with adverse side effects on the lips.
