Can Sculptra last forever? How long does it take for the collagen to die? Does it feel similar to fat?

It lasts at least two years and, yes, the studies were stopped at 2 years and the Sculptra was still going strong. However, no one knows how long it really lasts and I tell my patients they need maintenance over time to maintain their results. In my experience, nothing lasts forever, but Sculptra is great in the long run and low risk. Good luck. Dr. ALDO 

I’m sorry that you’ve had so much trouble getting the improved figure you desire. Nothing lasts forever, including our own fat, collagen and elastin. We lose all of these as we age. Sculptra is an excellent dermal filler to use in the buttocks and outer thighs because it is quite long lasting —about 2 to 3 years. However, in clinical studies I’ve reviewed and patients I’ve treated, I’ve never seen it last “forever”.
Because Sculptra works by stimulating the production of new collagen, you can get a really nice improvement that will look beautiful for quite some time. However, it may take many vials to obtain the level of improvement you want. I also recommend touch ups (not a full treatment) every year or two to keep the collagen in production. Collagen feels very soft and natural, much like fat. Please find a board-certified dermatologist who is an expert at body contouring with Sculptra, as this is a highly advanced procedure.

Thank you for sharing your excellent question.  Sculptra is thought to last for 2 years and at times can appear to last longer but it is by no means permanent. I would seek out an ASPS board certified plastic surgeon for a second opinion on the best treatment options for your hips.  Hope this helps.
