How do Sculptura and Bellafill compare?

Sculptra and Bellafill are both effective bio-stimulatory fillers capable of addressing the sunken areas on your cheeks and temples.
Sculptra, composed of poly-L-lactic acid, works gradually to stimulate collagen growth and improve skin texture and volume. While Sculptra has shown positive results for you, it's true that its effects typically last up to 2 years, necessitating repeat treatments.
On the other hand, Bellafill, which combines collagen gel and PMMA microspheres, provides both an immediate plumping effect and prolonged collagen growth over time. While Bellafill is commonly used for treating acne scars, it's equally effective in addressing facial volume loss. A key advantage is its long-lasting results, potentially enduring for 5 years or more.
In essence, Bellafill could be a suitable option if you're looking for a longer-lasting solution to Sculptra. However, this decision should be made in consultation with a skilled injector who can assess your specific needs and guide you accordingly.

Both are collagen stimulators used to replace long-term volume loss. Sculptra is FDA approved for this indication and Bellafill is not. Off label use of fillers is routinely done by the experienced physician. Sculptra (PLLA) is eventually degraded by the body while Bellafill is not. The corrections will look similar in the long run, but Bellafill will give a correction during the period while you body is creating its own collagen because of the carrier - bovine collagen. Sculptra's carrier is saline/water and will therefore not show any correction for 3-4 months. In the long run, Bellafill will be more economic because of its duration but Sculptra will be less expensive in the short term. My preference would be placement of Bellafill in the temples with cannula technique, in the superficial plane between the superficial and deep temporal fascia.
