How long do filler results last?

Hyaluronic acid fillers remain effective for 6-18 months depending on the area and product type. Lip fillers generally last 6-9 months, while cheek and chin fillers last 12-18 months. The body's natural metabolism gradually absorbs the filler over time. Regular maintenance sessions ensure continuity of results. In some patients, repeated θεραπειες may extend duration as fillers also stimulate collagen production.
