Ellansé: Why Does It Last Up to 2 Years?
Ellansé is a collagen booster that uses PCL microspheres to stimulate your body's own collagen production, with results lasting 1 to 4 years.
If you've been researching Ellansé and wondering "why does it last longer than regular HA Filler?" — you're not alone. The short answer is that Ellansé belongs to a different category altogether: it's a collagen booster that stimulates your body to produce new collagen, rather than simply filling space and getting absorbed like HA Filler.
What Is Ellansé?
Ellansé is a collagen-boosting Filler that combines PCL (polycaprolactone) microspheres suspended in a carrier gel. Like a standard HA Filler, it creates immediate volume right after the procedure — but it also gradually stimulates your body's own collagen production over time, so results continue to build.
Fillers are a category known for delivering natural-looking results through gradual structural support, and Ellansé stands out within that category as a long-lasting, collagen-inducing option.
Two key points to remember:
- Immediate + progressive results — volume is created right after the procedure, followed by ongoing Collagen stimulation that improves Skin Texture over time
- PCL degradation + Collagen regeneration cycle — the mechanism behind its 1–4 year duration
This dual-action cycle is what defines the Ellansé experience.
PCL (Polycaprolactone)*: A well-established biodegradable polymer used in medical-grade absorbable sutures. As it gradually breaks down, it triggers the body's own Collagen production.
The Science Behind Long-Lasting Results — Collagen Induction Mechanism
Ellansé's longevity comes down to a two-phase mechanism:
| Phase | Timing | Effect |
|---|---|---|
| Phase 1 — Carrier Gel Effect | Immediately after procedure ~ 3 months | Immediate volume creation; carrier gel gradually absorbs |
| Phase 2 — PCL Collagen Stimulation | 3 months ~ 24 months | PCL degrades and triggers progressive buildup of your own Collagen |
| Complete Degradation | 12–36 months (depending on formulation) | PCL fully absorbed; only your own Collagen remains |
You might expect volume to decrease as the carrier gel absorbs — but that's precisely when your own Collagen kicks in to fill the space, maintaining the result. This is fundamentally different from HA Filler, which simply fills, gets absorbed, and disappears.
Ellansé is available in four formulations (S, M, L, E), each with different PCL particle sizes designed to deliver different durations:
- S (Short) — approximately 1 year — fine facial areas
- M (Medium) — approximately 2 years — moderate volume areas
- L (Long) — approximately 3 years — deeper structural support
- E (Extended) — approximately 4 years — deep facial contouring
The right formulation depends on the treatment area and how long you'd like results to last.
Microspheres*: Tiny spherical particles. The PCL microspheres in Ellansé are the key driver of Collagen induction.
How Ellansé Differs from HA Filler
Comparing Ellansé and HA Filler is a common point of confusion. Here's a clear breakdown:
| Feature | HA Filler | Ellansé |
|---|---|---|
| Active Ingredient | Hyaluronic acid | PCL + carrier gel |
| Immediate Effect | Strong | Strong |
| Duration | 6–12 months | 1–4 years (formulation-dependent) |
| Collagen Stimulation | Mild | Strong |
| After Absorption | Disappears | Maintained by your own Collagen |
| Natural Appearance | Natural immediately | Progressively natural over time |
| Reversal / Dissolution | Possible (hyaluronidase) | Not possible (must await natural degradation) |
The most critical difference is that Ellansé cannot be dissolved. HA Filler can be reversed quickly with hyaluronidase if a complication arises, but with Ellansé, you must wait for the PCL to degrade naturally. This makes the choice of provider and a thorough pre-procedure consultation especially important.
Pre-Procedure Checklist — Is Ellansé Right for You?
Ellansé is not recommended for everyone. The following factors need to be assessed beforehand:
- Pregnancy or breastfeeding — insufficient safety data available
- Active inflammation or Acne at the treatment site — increases procedural risk
- Keloid-prone skin — risk of nodule formation
- Autoimmune conditions — unpredictable tissue response
- Current use of anticoagulants — increased risk of Bruise and Swelling
- Desire for significant full-face volume change — combination with HA Filler may be more appropriate
- Preference for short-term results (a few months) — HA Filler may be a better fit
Consult your provider promptly if any of the following apply:
- History of adverse reactions to collagen booster procedures
- Previous permanent Filler (e.g., silicone) injected in the same area
- Suspected allergy to PCL or carrier gel components
Pre-procedure safety guidelines also emphasize that for long-lasting and semi-permanent fillers, the provider's experience and a comprehensive consultation are essential.
Frequently Asked Questions
Q. Does Ellansé really last 2–4 years after a single session?
A. Many patients do report results lasting as long as the formulation suggests (M = ~2 years, L = ~3 years, E = ~4 years). That said, individual results can vary significantly depending on your metabolic rate, how much movement occurs in the treated area, and your body's Collagen-producing capacity. Even with the same formulation, some patients may notice effects fading a year earlier, while others may find results lasting even longer.
Q. What happens if a complication occurs?
A. Unlike HA Filler, there is no dissolving agent (such as hyaluronidase) that works on PCL. If issues such as nodules, excess volume, or asymmetry arise, management may require waiting for natural degradation — which can take several months to over a year — or, in some cases, medical removal. For this reason, starting with a conservative volume on the first session is generally recommended.
Q. Can Ellansé be combined with HA Filler?
A. Combination approaches do exist. A common method involves using Ellansé to stimulate Collagen in deeper layers while using HA Filler to fine-tune volume in more superficial areas. However, decisions around timing, treatment sites, and dosage require a professional clinical assessment. If you're considering both in a single visit, please make sure to have a thorough consultation before proceeding. Please note that this article is for general informational purposes only. Whether either procedure is suitable for you should be determined through a direct consultation with a qualified medical professional.
