While Fillers like Hyaluronic Acid (HA) only last a few months, there are longer lasting injectable treatments that can provide more enduring results , upto 18-24 months. For example, Hydroxyapatite is a bone-like mineral filler that can be used to shape the cheeks and jaw, and can last longer than HA filler. Also, the newer filler Elanse is also longer lasting. Blood-based Injectable treatments such as PRP and HYPPP are also long-lasting, although these are not technically fillers, but rather target skin rejuvenation.
