Short answer: A biostimulator is an injectable treatment that prompts your body to produce its own collagen gradually over time, rather than adding instant volume the way traditional fillers do. The two FDA-approved biostimulators are Sculptra (poly-L-lactic acid) and Radiesse (calcium hydroxyapatite), and both are offered at Elase.
Here’s a little truth about beauty that doesn’t get said often enough: some of the best results aren’t the ones you see overnight. They’re the ones that build slowly, like a good habit, or a season that turns when you’re not quite looking.
That’s the whole idea behind biostimulators, one of the most talked-about treatments in aesthetics right now. If you’ve been hearing the word everywhere and nodding along while quietly wondering what it actually means, you’re in the right place.
Think of a traditional filler as the little luxury you treat yourself to today. It’s instant and lovely, right now. A biostimulator is more like the contribution you make to your retirement account: quiet, steady, compounding in the background until one day you look up and realize how much it’s grown. Think of it as your skin’s 401(k).
What is a biostimulator?
Most injectables you’ve heard of work by adding volume. Biostimulators play a different game: instead of filling a space, they gently encourage your body to make more of its own collagen—the protein that keeps skin firm, smooth, and resilient, and the one we naturally make less of with each passing year. So rather than adding something to your face, you’re rebuilding structure from within. The results arrive gradually and tend to look like you, just well-rested and a little more lit-from-within.
Biostimulators vs. fillers: what’s the difference?
A traditional hyaluronic acid filler adds volume the moment it goes in, and that volume is what you see. A biostimulator works on a delay. It sets off your skin’s own collagen-building process, so the change reveals itself over weeks and months and tends to last considerably longer. Fillers answer “I’d love a little more here, today.” Biostimulators answer “I’d love better skin quality and structure that builds over time.” Many people, with their provider’s guidance, end up loving a thoughtful mix of both.
Sculptra vs. Radiesse: which is right for you?
Two paths, same destination, using your own collagen.
Nationally, Elase offers two biostimulators, and they each have their own personality. Sculptra is the slow-and-steady one: pure collagen support over a short series of sessions. Radiesse is the dual-action one: a little structure right away, plus collagen support that keeps working. Here’s how they compare:
| Sculptra | Radiesse | |
| Made from | Poly-L-lactic acid (PLLA) | Calcium hydroxyapatite (CaHA) — a mineral found naturally in bone |
| How it works | Pure collagen stimulation; no instant volume | Dual action: immediate structure from the gel, plus collagen stimulation over time |
| When you’ll see results | Gradual, over several weeks | Some structure right away, with collagen results building over time |
| How long it lasts | Often 2+ years after a series | Typically around 12–18 months |
| FDA-approved areas | Facial wrinkles and folds | First and only filler FDA-approved for both the face and hands |
| Best suited for | A soft, natural, long-game evolution and overall skin quality | Versatile volume plus collagen support, including hands |
Different rhythms, same goal: your own collagen, working quietly on your behalf.
How long do biostimulator results last?
Because you’re growing real collagen rather than borrowing volume, the results are built to last. Sculptra results often hold for two years or more after a completed series, while Radiesse typically lasts around 12 to 18 months. Individual results vary, and your provider can give you a realistic timeline based on your skin and your goals.
What to expect from biostimulator treatment
Here’s the part we’ll always be straight with you about: patience is part of the magic. There’s no dramatic “before and after” selfie on day one. What you’ll notice instead is skin that gradually looks smoother, feels firmer, and catches the light a little differently. Treatment itself is quick, downtime is usually minimal, and your provider will walk you through everything (including any temporary tenderness, swelling, or bruising) before anything begins. Everyone’s skin and timeline is a little different, so the best plan is never one-size-fits-all. It’s one your provider builds with you.
Which season are you in?
This question will help you answer which treatment is right for you. Maybe you’ve got a wedding on the horizon and want to start now so your skin is glowing by the time the photos roll around. Maybe you’re coming through a big life shift and choosing yourself a little more deliberately these days. Or maybe you’ve simply decided this is the year you invest in the long game. Biostimulators reward the people who plan ahead, which makes them a beautiful fit for whatever chapter you’re in.
Because here’s what we believe, all year long: there’s no single standard for beauty, and no wrong season to feel like yourself again. We’re just here to support how you look, feel, and live through every one of them.
Frequently asked questions
How much do biostimulators cost? Cost depends on which product you choose, how many areas you’re treating, and the number of sessions your plan calls for. Sculptra is typically done as a short series, while Radiesse often delivers results in a single session with occasional touch-ups.

Are biostimulators safe? Both Sculptra and Radiesse are FDA-approved and, when administered by a licensed provider, are generally well-tolerated. As with any injectable, your provider will review your medical history and any risks with you first, so you can make an informed decision.
Do biostimulator injections hurt, and is there downtime? Most people find treatment very manageable, and many products include or are paired with numbing for comfort. Downtime is usually minimal — some temporary swelling, redness, bruising, or tenderness at the injection site is common and tends to settle quickly. Most people return to their normal day soon after.
How many sessions will I need? It depends on the product and your goals. Sculptra is usually done as a series of sessions spaced a few weeks apart, while Radiesse often shows results from a single session. Your provider will map out a plan tailored to you.
Who is a good candidate for biostimulators? They’re a lovely option for adults noticing gradual volume loss or a change in skin firmness who want natural-looking results that build over time rather than an instant change. The best way to know if they’re right for you is a quick consultation with one of our providers.
What areas can biostimulators treat? Commonly the cheeks, temples, jawline, and chin. Radiesse is also FDA-approved for the hands. Your provider can talk through which areas make sense for your goals.
