A few years back, if you wanted a rounder, lifted, more sculpted backside, your only real options were going under the knife or hauling around weights for months hoping genetics would meet you halfway. That's not the case anymore. The butt filler category has quietly grown into one of the most requested non-surgical procedures in the world — and 2026 is the year it stopped being a "quiet trend" and turned into a full-blown movement.
Patients want curves without the recovery, the scars, or the risks tied to fat transfer and BBL surgery. Clinics want products that lift, hold their shape, and don't migrate. And manufacturers — especially in South Korea — have stepped up with high-volume butt enhancement filler lines that finally deliver.
So which products actually live up to the hype? I dug through the formulations, the cross-linking tech, the volumes, the longevity claims, and pulled together a ranked list of the best body filler options on the market right now. Whether you're a clinic owner sourcing wholesale or a curious patient researching options before booking a consultation, this guide will help you understand what's worth your money in 2026.

What Is a Butt Filler, Exactly?
Before we dive into the rankings, a quick refresher. A buttock HA filler is an injectable gel — usually hyaluronic acid (HA) that's been cross-linked to make it thicker and longer-lasting — designed to add volume, lift, and contour to the gluteal area. Unlike fat grafting, there's no surgery, no liposuction donor site, and no general anesthesia. Unlike silicone implants, nothing permanent goes inside your body.
The procedure usually takes 30 to 60 minutes. Numbing cream or lidocaine handles the discomfort. You walk out the same day. Most people are back to normal life within 48 hours, though sitting directly on the area is discouraged for the first day or two.
What's changed in the last couple of years is volume capacity. Older HA fillers came in 1ml or 2ml syringes — fine for lips, useless for buttocks. The newer body filler vials hold 50ml, 70ml, even 100ml of product, which means clinics can finally treat large surface areas in a single, cost-effective session.
Korean manufacturers, in particular, have led this category. Their fillers are known for advanced HENM (High-Efficiency Nano Mesh) cross-linking technology, multi-stage purification that strips out residual BDDE, and competitive pricing that Western brands haven't been able to match.
Now — onto the list.
The Best 7 Buttock Fillers in the Market (2026)
1. Agasthi Body Filler — 10cc / 70cc / 100cc
Where to buy: [agasthibeauty.com](https://agasthibeauty.com , koreanfillers.com )
If I had to pick one product as the gold standard right now, Agasthi takes the top spot. It's not even particularly close. The reason is consistency — Agasthi has built a reputation among injectors for behaving exactly the way it's supposed to, every single time, regardless of which volume you're working with.
The lineup:
- Agasthi 10cc — for fine-tuning, hip dip touch-ups, or smoothing minor irregularities
- Agasthi 70cc — the workhorse vial, ideal for moderate buttock augmentation and standard hip dip correction
- Agasthi 100cc — the high-volume option for patients chasing dramatic projection
HA concentration: 20–24 mg/mL of cross-linked hyaluronic acid
What sets it apart:
- A unique viscoelastic structure that resists migration. Once placed, it stays placed.
- Soft enough to feel natural to the touch, but firm enough to give real lift
- Long-lasting effects of 12 to 24 months in most patients
- Minimal post-injection swelling, which means patients see "real" results faster
- Competitive wholesale pricing, especially for clinics buying the larger vials
Who it's best for: First-time body filler patients who want a reliable, natural-looking result, and clinics that need a versatile product they can use across multiple body areas (Agasthi works on hips, thighs, calves, and décolletage too).
If you're new to butt fillers, start here. There's a reason it's been climbing every "best butt filler" list across the aesthetic industry over the past two years.
2. Sedy Fill — 10cc / 60cc / 100cc
Sedy Fill (made by MayPharm) has cult status among injectors who prioritize a "soft-touch" result. Where Agasthi feels firm and structural, Sedy Fill feels like you. Like the volume was always there.
The lineup:
- Sedy Fill 10cc — small-area touch-ups, smoothing skin surface irregularities
- Sedy Fill 60cc — localized buttock and upper-glute correction
- Sedy Fill 100cc — full-volume buttock augmentation, hip enhancement
HA concentration: 24 mg/mL cross-linked HA
What sets it apart:
- HENM cross-linking combined with 3-Staged Ultra-Fine Microbead Blending — basically, the gel particles are uniformly sized, which translates to smoother injection flow and fewer lumps
- 100% non-animal HA, low allergic reaction risk
- 12 to 24 months of duration with proper aftercare
- Almost invisible injection marks, even immediately after the procedure
- Quick recovery — most patients resume normal activity within hours
Who it's best for: Patients who want the most natural-feeling result possible. People who've had bad experiences with firmer fillers and complained about the "implant feel." Sedy Fill blends so well into native tissue that, honestly, even hands-on partners can't tell.
3. Rabianca Body Filler — 70cc / 100cc
Rabianca is the heavy lifter. Plain and simple. If you walk into a consultation and tell the injector "I want maximum projection, I want this to last as long as possible, and I'm not afraid of a firmer feel" — they're probably reaching for Rabianca.
The lineup:
- Rabianca 70cc — the standard vial, designed for high-volume efficiency
- Rabianca Max 100cc — the larger format for full-area augmentation of buttocks, breasts, and thighs
HA concentration: 20–24 mg/mL cross-linked HA
What sets it apart:
- 3-Staged Microbeads Technology for exceptional gel durability
- Volume retention of 24 to 36 months in many patients (one of the longest in the category)
- 100% absorbable and reversible — if needed, hyaluronidase dissolves it
- Trusted by top-tier aesthetic clinics in Seoul, which is the closest thing to an industry stamp of approval
Who it's best for: Patients with thicker skin, athletes who want a firm "lifted-glute" look that holds up under muscle movement, and anyone prioritizing longevity over softness. This is also a strong pick for second-round treatments, where the patient already knows what HA fillers feel like and wants something with more staying power.
4. DeneB Classic 10mL Body Filler
DeneB (made by BioPlus) is the precision tool of the group. It comes in a smaller 10mL syringe — not designed for full-volume augmentation, but absolutely brilliant for targeted, technique-driven work.
The lineup:
- DeneB Classic-S (Soft) — softer gel, for blending and shallow correction
- DeneB Classic-H (Hard) — higher viscosity, for deeper subcutaneous projection
HA concentration: 20 mg/mL cross-linked HA, with optional 0.3% lidocaine
What sets it apart:
- MDM patented technology — combines micro-bead monophasic structure with multi-crosslinking for serious viscoelastic stability
- 12 to 16 months of natural-looking results
- CE-approved and KFDA-certified
- Excellent for "fine-tuning" work after a larger filler placement (think: layering on top of Agasthi or Rabianca)
Who it's best for: Patients who want subtle, controlled enhancement, or who are addressing asymmetry rather than total volume loss. Also great for clinics that want a high-end "finishing" filler in their toolkit. DeneB pairs beautifully with the high-volume products further down this list — use a 70cc or 100cc vial for the bulk of the work, then DeneB to refine.
5. B-esta Body Filler — 10cc / 50cc
B-esta (developed by BNC Global) is a strong, no-nonsense option that's been quietly dominating the mid-tier of the butt enhancement filler market. It contains 24 mg/mL of stabilized hyaluronic acid plus 3 mg/mL of lidocaine baked right into the formula — which means painless injection without needing a separate numbing protocol.
The lineup:
- B-esta 10cc — pre-filled syringe for smaller-area work
- B-esta 50cc — vial for larger augmentation procedures on buttocks, breasts, calves
HA concentration: 24 mg/mL stabilized HA + 0.3% lidocaine
What sets it apart:
- Single application can deliver 1.5 to 2 years of results — among the longest in this guide
- Highly purified HA via BNC Global's patented method
- Procedure time is just 30 to 40 minutes
- Lidocaine integrated for built-in patient comfort
- Hypoallergenic, non-animal-origin formula
Who it's best for: Clinics that want a reliable body filler with built-in anesthetic, and patients who are nervous about pain during the procedure. B-esta also performs well for post-liposuction smoothing — if a patient came in for lipo and now has minor irregularities, B-esta can even those out without a second surgery.
6. Maxy Fill 70mL
Maxy Fill (manufactured by Quivermedic) is one of those products that doesn't get the marketing budget of the bigger names but absolutely earns its spot through sheer performance. The clinical numbers back it up: 92% patient satisfaction in studies, 12 to 15 months of duration on average, and one of the better safety profiles in the category.
The lineup:
- Maxy Fill 70cc — 70mL high-volume vial, designed for body contouring at scale
HA concentration: 20 mg/mL cross-linked HA + 3 mg/mL lidocaine
What sets it apart:
- HENM (High Elasticity Network Matrix) technology ensures even distribution and slow degradation
- 98.7% purity in third-party testing — among the highest in the category
- Reversible with hyaluronidase if needed (always a nice safety net)
- Dosage protocol: 30–40cc per buttock per session, with a max of 100cc per session for first-time patients
- Larger vial means fewer "syringe swaps" mid-procedure, which keeps things sterile and efficient
Who it's best for: Clinics doing high-volume work who want a workhorse product that's affordable per cc, and patients who want significant projection without committing to a top-tier price point. Maxy Fill is the value pick on this list — solid quality, lower wholesale cost.
7. Wanna Fill 50cc
Rounding out the list is Wanna Fill, made by Pharma Research Products. It's a 100% cross-linked hyaluronic acid filler that uses HENM technology and comes in two consistencies — Soft and Hard — depending on what kind of result the patient wants.
The lineup:
- Wanna Fill Soft 50cc — for subtle volume, smoothing, blending
- Wanna Fill Hard 50cc — for sculpting and deeper projection
HA concentration: 24 mg/mL cross-linked HA
What sets it apart:
- 12 to 15 months of duration, extending up to 24 months with good aftercare
- Strong cohesiveness — gel maintains shape without migrating
- Optimal gel hardness that's controllable during injection (a feature injectors love)
- Versatile across breast, buttock, leg, and even intimate contour applications
- Crystal-clear gel structure visible during injection, which helps placement accuracy
Who it's best for: Injectors who want flexibility — having both Soft and Hard options in the same product line means you can tailor the result to each patient's anatomy. Patients who want a mid-range price with results that punch above their weight.
How to Choose the Right Butt Filler for You
Here's where most articles on this topic fall apart — they list products and call it a day. Choosing the right filler is about more than picking the highest-rated one. It depends on:
Your starting anatomy. Flat, sagging, or asymmetric? The answer changes which filler makes sense. For significant volume loss, you'll want something like Agasthi 100cc, Rabianca 100cc, or Maxy Fill 70cc. For subtle correction or hip dips, smaller volumes like DeneB or B-esta 10cc are smarter choices.
Your timeline. Need it to last as long as possible because you don't want to come back? Rabianca and B-esta are the longevity champions. Comfortable with maintenance every 12 months? You have more options.
Your tissue type. Thicker, denser tissue handles firmer fillers (Rabianca, Wanna Fill Hard) better. Slimmer patients with less native tissue may want softer products that integrate more naturally (Sedy Fill, Wanna Fill Soft).
Your budget. Prices vary significantly. The premium brands (Agasthi, Rabianca) cost more per cc but tend to last longer, which can offset the gap. Mid-tier options (Maxy Fill, Wanna Fill) deliver excellent value if you're cost-conscious.
Side Effects, Safety, and What to Expect
Even the best body filler comes with risks. The most common are temporary: swelling, mild bruising, tenderness at the injection site. These usually resolve within 3 to 7 days.
Rare but more serious complications include vascular occlusion (filler accidentally entering a blood vessel), infection, and migration. These risks are dramatically reduced when you choose:
- A licensed, experienced injector
- A reputable, properly sourced product (counterfeit fillers are a real problem in this industry)
- A clinic that follows proper sterile protocols and has hyaluronidase on hand for emergencies
The good news with HA fillers — including every product on this list — is that they're reversible. If you don't like the result, or something looks off, hyaluronidase dissolves the filler within 24 to 48 hours.
Aftercare That Actually Matters
To get the most out of your buttock HA filler:
- Don't sit directly on the treated area for 24 to 48 hours
- Skip the gym for at least 2 weeks (no squats, no spin class, no pressure-based exercises)
- Drink plenty of water — HA binds to water, so hydration helps the filler do its job
- Sleep on your side or stomach for the first week
- Schedule a touch-up before the filler fully dissolves, not after
Final Thoughts
The 2026 butt filler market is in the best place it's ever been. Korean manufacturers have pushed the technology forward dramatically, prices have come down for clinics buying wholesale, and the safety record on properly administered HA body fillers is genuinely strong.
If you're looking for a single recommendation, Agasthi earns the top spot for its versatility, consistency, and the fact that it works for both first-timers and experienced patients. Rabianca wins on longevity. Sedy Fill wins on natural feel. Maxy Fill wins on value.
But the real takeaway is this: the right filler for you depends on a real consultation with a real injector who can assess your anatomy, your goals, and your tolerance for downtime. Don't pick a product off a list. Pick a clinic, then trust them to pick the product.
That said — now you know what to ask about.
