If you have decided a non-surgical BBL is right for you, the next question is which injectable should do the lifting: Sculptra or Radiesse? Both are FDA-cleared biostimulators, both build your own collagen, and both are used every week at our Edgewater studio. But they behave differently — and the right choice (often, the right combination) depends on your body and your goals.
Here is the honest breakdown.
What Is a Sculptra BBL?
Sculptra is a poly-L-lactic acid (PLLA) collagen stimulator. Injected into the glutes, it does not add volume directly the way a filler does — instead it triggers your body to build new collagen over the following weeks and months. Results appear gradually across a series of two to three sessions, which makes the change look completely natural: nobody can point to the day it happened.
What Is a Radiesse BBL?
Radiesse is a calcium hydroxylapatite (CaHA) filler — a substance naturally found in the body. Used hyper-diluted for the glutes, it delivers two things at once: immediate visible volume and contour on day one, plus ongoing collagen stimulation that improves skin quality, smoothness, and shape over time. It is also excellent for softening cellulite, dimples, and stretch marks.
Sculptra BBL vs Radiesse BBL: Side by Side
| Factor | Sculptra BBL | Radiesse BBL |
|---|---|---|
| What it is | Poly-L-lactic acid (PLLA) collagen stimulator | Calcium hydroxylapatite (CaHA) filler, hyper-diluted |
| Speed of results | Gradual, over weeks to months | Visible volume immediately |
| Sessions needed | 2 to 3, spaced weeks apart | Often just 1 |
| Longevity | 2 years or more | 18 to 24 months |
| Best for | Natural, gradual added fullness and projection | Fast contour, cellulite, skin quality, hip dips |
| The experience | Builds so gradually nobody notices a sudden change | Instant gratification, refined over weeks |
So Which One Should You Choose?
Choose Sculptra if you want the most gradual, natural-looking change, you are not in a rush, and your main goal is added fullness and projection built over a few months.
Choose Radiesse if you want visible results quickly — say, before an event — or your main concerns are contour, hip dips, cellulite, and skin quality rather than maximum volume.
Choose both if you want the best of each. This is exactly what our signature Zeugma Butt Lift (ZBL) does: Radiesse provides the immediate lift and contour while Sculptra builds lasting foundation volume behind it. For most clients, the combination outperforms either product alone.
What They Cost
Pricing depends on how much product your plan needs — the honest answer for any injectable butt lift. We covered typical Miami ranges in detail in our non-surgical BBL pricing guide; your exact quote comes from a free consultation, with tiered pricing and 0% or low-interest financing available.
Frequently Asked Questions
Is one safer than the other?
Both are FDA-cleared products with long safety records when administered by licensed medical injectors. What matters most is who is injecting: technique, dilution, and placement are everything in the glute area. Avoid any provider offering silicone or unregulated “biopolymer” injections at any price.
Which one lasts longer?
Sculptra results typically last two years or more; Radiesse results typically last 18 to 24 months. Both fade gradually as your own collagen slowly remodels — see our full post on how long a non-surgical BBL lasts.
How many sessions will I need?
Radiesse often shows meaningful change in one session. Sculptra is usually planned as a series of two to three sessions spaced several weeks apart. Combination plans are personalized at your consultation.
Does one hurt more than the other?
Both are performed with local numbing and a cannula, and most clients rate discomfort as mild. The glutes are actually one of the more comfortable areas to treat.

Hip dips — the natural inward curves on the sides of your hips, between hip bone and thigh — are one of the most searched body concerns in aesthetics, and one of the most misunderstood. First things first: hip dips are completely normal anatomy, determined by your bone structure and how your muscle and fat
One of the best things about a non-surgical BBL is how little it disrupts your life — no hospital stay, no weeks on a donut pillow, no sitting bans. But “minimal downtime” does not mean “no aftercare.” What you do in the first days and weeks after your appointment directly affects how smooth, even, and
It is the first question almost everyone asks at a non-surgical BBL consultation: “How long will this actually last?” It is a fair question — nobody wants to invest in their curves and watch them disappear in six months. The honest answer: with the right products and a little maintenance, a non-surgical BBL typically lasts
Miami summers are brutal on skin. By September, months of intense UV, humidity, salt water, chlorine, and sweat have left most of us with new dark spots, rougher texture, dehydration that no moisturizer seems to fix, and fine lines that look deeper than they did in May. Here is the good news: fall is the
