Migrated Filler

Hyaluronidase breaks down hyaluronic acid filler, with most of the change visible within twenty four to forty eight hours. Dense or long-standing product often needs more than one session, and providers typically wait two weeks before considering any new placement.

The under eye is the most common migration site because the skin is thin and lymphatic drainage is limited. Product that has spread here reads as persistent puffiness, which patients often mistake for aging rather than filler.

Product crossing the lip border creates the shelf above the upper lip that patients describe as a filler mustache. The vertical injection approach places product within the body of the lip rather than along the border, which reduces that risk.

Midface product migrates downward over years, creating fullness below where it was placed and flattening the cheek it was meant to support. Recognizing this pattern matters, because adding more product to the cheek makes it worse.

Retreatment after dissolving involves different decisions than the original session: lower volume, deeper placement, and a firmer product that resists spread. Providers also space treatments further apart to avoid the layering that caused the problem.

Migration is often the result of treating one feature repeatedly instead of addressing the structure around it. Planning the face as a whole reduces the volume any single area requires.
