It is explained whether fillers can migrate in the face. The myth that fillers "travel" across the face is debunked as false. Instead, filler may shift by a few millimeters. This depends on the technique used and the product itself. Excessive amounts, the wrong injection depth, or an unsuitable filler are relevant factors, as even the best technique reaches its limits if the product is not of high quality. Such fillers can behave unpredictably in the tissue. Achieving a natural result that stays in place requires both the right technique and a high-quality filler. If either aspect is missing, it becomes difficult to achieve the desired outcome. In practice, quality is relied upon, such as that of Decoria fillers from Sweden.
