Hyaluronic acid dermal fillers last for a maximum of 12 months. Those who want long-lasting semi permanent dermal fillers need products like Radiesse, Sculptra, Ellansè, Aquamid, Bellafill and Artefill. Aquamid, Bellafill and Artefill are permanent quality dermal fillers but unfortunately in some cases have created problems for patients, which is why we do not sell permanent fillers. If you need long-lasting dermal fillers, you can buy Radiesse, Sculptra, Ellansè or our new Fillan X (similar to Ellanse), GANA PH (PLLA Sculptra-like Filler) or GANA CH (made with filler-like calcium hydroxyapatite Radiesse.) Our alternatives have a much lower price while maintaining the same high quality, made in South Korea.
