Board-Certified Clinician
Poly-L-lactic acid biostimulators represent a fundamentally different approach to volume and contouring, one that works with your body's regenerative biology rather than adding a foreign substance. When PLLA is injected into the subcutaneous tissue, it stimulates fibroblast activity and drives new collagen synthesis in the treated area. Volume builds gradually over 6–12 weeks as your own tissue responds.
The result is not a filler effect.It is genuine tissue transformation, natural in appearance, progressive in development, and significantly longer-lasting than temporary fillers because the collagen produced is your own. PLLA protocols for the gluteal region require clinical precision in injection depth, volume distribution, and anatomical knowledge to produce the aesthetic outcome without complication.
At Arbour Longevity, every gluteal biostimulator treatment is performed, with the anatomical expertise and clinical rigor that distinguishes a medical procedure from a cosmetic service.
How PLLA Works
Injected into subcutaneous tissue · Stimulates fibroblast activity · Drives new collagen synthesis · Volume develops gradually 6–12 weeks
Why It Looks Natural
Results are your own collagen, not a synthetic filler · Progressive development prevents sudden change · Tissue-specific volume distribution

2–4 sessions typically recommended · Spaced 4–8 weeks apart · Full results visible at 3 months · Longevity 2+ years
Pricing
All pricing discussed at consultation · Volume of product and number of sessions determined by individual anatomy and goals
Each protocol uses a different biostimulating mechanism, or combines multiple. Your clinician selects the protocol best suited to your anatomy, goals, and tissue quality at consultation. All involve off-label use of FDA-approved products in the gluteal region, disclosed in full before treatment.
Primary Protocol · Most Popular
The gold standard of non-surgical gluteal biostimulation.
Sculptra® is the most widely used PLLA biostimulator for non-surgical gluteal augmentation globally. Its poly-L-lactic acid microparticles stimulate fibroblast-driven collagen production over 6–12 weeks, gradually building volume, improving skin texture, and enhancing projection with results that typically last 2 years or more. It is the foundation of Arbour Longevity's gluteal contouring program and the most appropriate protocol for patients seeking meaningful, lasting volume enhancement.
Mechanism: PLLA microparticles trigger a controlled fibroblastic response · Stimulates Type I and III collagen synthesis · Volume builds progressively as new collagen matrix forms · Absorbs completely over time, results sustained by new tissue
Addresses
Immediate + Stimulating Protocol
Immediate volume with long-term biostimulation.
Radiesse® offers a dual-action mechanism uniquely suited for patients who want both immediate structural improvement and progressive collagen stimulation. The calcium hydroxylapatite microspheres provide an immediate volumizing scaffold while simultaneously stimulating collagen synthesis over time. Its thicker consistency makes it particularly effective for structural hip dip correction and areas requiring more immediate definition alongside the progressive collagen benefit.
Mechanism: CaHA microspheres provide immediate volume scaffold · Stimulates fibroblast activity and collagen production · Carrier gel metabolizes over weeks · Collagen matrix sustains results as CaHA particles are gradually absorbed
Addresses
Regenerative Enhancement · Combination Protocol
Platelet-Rich Fibrin · Combined with PLLA or CaHA Protocol
Your own growth factors, amplifying the biostimulation.
Platelet-Rich Fibrin (PRF) is the second-generation evolution of PRP, using a slower centrifugation process to preserve a greater concentration of growth factors within a fibrin matrix. When combined with PLLA or CaHA biostimulator treatment, PRF adds a regenerative growth factor layer that may accelerate and enhance collagen stimulation, improve tissue quality, and support skin texture improvement beyond what the biostimulator alone achieves. Drawn from your own blood, no synthetic additives.
Mechanism: PRF fibrin matrix releases PDGF, TGF-β, VEGF, and IGF-1 growth factors · Synergizes with PLLA/CaHA biostimulator response · May accelerate collagen synthesis and improve tissue vascularization · 100% autologous, your own biology
Addresses
Premium Upgrade · Advanced Regeneration
The deepest regenerative enhancement available.
Exosome therapy delivers over 200 growth factors, cytokines, and signaling proteins that drive tissue regeneration at a cellular level beyond what PRF or biostimulators alone can achieve. As an upgrade to any PLLA or CaHA protocol, exosome enhancement may produce superior collagen stimulation, accelerated results, improved skin quality, and more significant cellulite and laxity improvement, particularly in patients with advanced skin aging, prior treatments, or those seeking maximum outcome.
Mechanism: Exosomes deliver 200+ growth factors directly to target tissue · Stimulate cellular repair, collagen, and elastin pathways · Complement and amplify the biostimulator response · Superior regenerative depth compared to PRF

The primary indication for PLLA gluteal biostimulation. Progressive collagen production builds volume gradually, improving projection, fullness, and the overall shape of the gluteal region without the risk, recovery, or artificiality of implants or fat transfer surgery.
Hip dips, the inward curve between the hip and thigh, are a structural feature of the lateral femoral depression that responds well to targeted biostimulator placement. Radiesse® and Sculptra® injected into the lateral gluteal region can significantly soften hip dip appearance, improving the waist-to-hip silhouette without surgery.
Collagen-stimulating biostimulators improve not just volume but skin quality in the treated area, addressing the laxity, thinning, and textural irregularities that develop with age, weight fluctuation, and post-pregnancy changes. PRF and exosome combinations enhance this skin quality outcome significantly.
Strategic gluteal and hip volume enhancement changes the apparent waist-to-hip ratio, creating the hourglass silhouette through tissue-level contouring rather than surgery. Protocol design accounts for your specific anatomy to produce the proportional enhancement that best suits your body's natural architecture.
The collagen remodeling stimulated by PLLA biostimulators addresses the structural changes that contribute to cellulite appearance, improving the dermal-subdermal matrix that creates skin dimpling. Most patients report measurable improvement in skin texture and cellulite appearance following a complete treatment series, particularly when combined with PRF or exosome enhancement.
Non-surgical biostimulator augmentation is not the right choice for patients seeking large-volume results that require surgical intervention. Our clinician will assess your anatomy and goals honestly at consultation, and will refer for surgical consultation if your goals are better served by surgery. Honest assessment is Arbour Longevity's standard.

Frequently Asked Questions
Perfect Butt Augmentation uses injectable biostimulators, primarily poly-L-lactic acid (PLLA, brand name Sculptra®) and calcium hydroxylapatite (Radiesse®), to gradually increase gluteal volume, correct hip dips, and improve skin texture without surgery. Results develop over 6–12 weeks as the body's own collagen production is stimulated in the treated area. Both products are used off-label for this indication, disclosed in full at consultation.
Sculptra® (poly-L-lactic acid) acts as a biostimulator, it doesn't add volume directly but triggers your body's own collagen synthesis. Over 6–12 weeks, new collagen production builds volume and improves skin quality in the treated area. Results are natural-appearing, develop progressively, and typically last 2 years or more. Multiple sessions are usually recommended. Sculptra® is used off-label for gluteal augmentation, this is disclosed at consultation.
When performed by a qualified clinician using appropriate injection technique and anatomical knowledge, non-surgical gluteal augmentation with PLLA and CaHA biostimulators has a well-established safety profile. At Arbour Longevity all procedures are performed. The primary risks nodule formation uneven distribution and suboptimal results are significantly mitigated by clinical expertise and proper injection technique. All risks are discussed at consultation.
Arbour Longevity in Ann Arbor, Dexter offers Perfect Butt Augmentation using Sculptra® PLLA, Radiesse®, PRF combination, and exosome enhancement protocols. All treatments are clinician-administered. We serve Ann Arbor, Dexter, Ypsilanti, Saline, Plymouth, Canton, and Southeast Michigan.
A Brazilian Butt Lift (BBL) is a surgical procedure requiring general anesthesia, liposuction, and significant recovery. It can produce larger volume changes but carries meaningful surgical risk including fat embolism. Non-surgical biostimulator augmentation at Arbour Longevity requires no surgery, no anesthesia, no donor site, and minimal downtime, with progressive, natural results lasting 2+ years. It is ideal for moderate enhancement, hip dip correction, skin quality improvement, and patients who prefer to avoid surgical risk.
Most patients require 2–4 sessions spaced 4–8 weeks apart for optimal results. The exact number depends on your anatomy, starting point, and desired outcome, determined at consultation. Additional sessions beyond the initial series can further enhance results, and annual maintenance sessions help preserve and extend outcomes over time.
"I didn't want surgery but wanted something real. The Sculptra® series at Arbour Longevity gave me results I genuinely didn't think were possible without going under the knife. Three sessions and the change is visible to everyone."
"The hip dip correction was what I was after. The Radiesse® combined with Sculptra® addressed the structural issue, not just filled it temporarily. Six months later and it still looks exactly as it did at peak result."
"What I appreciated most was the honesty at consultation. She told me exactly what was achievable and what wasn't. The results matched what she described precisely. That clinical integrity is rare."
