PENIS FILLER (HYBRID-ULTIMATE)®

Hybrid-Ultimate® is a bio-stimulatory filler designed to stimulate neo-collagenesis,with initial collagen deposition typically observed at 6–8 weeks and continuedmaturation for up to 24 months. This process results in the formation of dense,well-integrated connective tissue within the penile shaft, producing firmness and bio-mechanical properties closely resembling native tissue. Patient-reported outcomes, consistently indicate that post-treatment feel and functional characteristics are indistinguishable from natural penile anatomy.

Penis filler works within the body’s natural limits. unlike breast implants, you can’t simply “pick a size.” The penis is surrounded by dense fascia and skin that allow only safe, harmonious expansion. With Hybrid-Ultimate®, most clients achieve their optimal size at 30–40 ml over 2–3 sessions, seeing around 1–1.5 inches of extra girth (sometimes close to 2 inches) and 50–100% more flaccid length. These results are within the tissue’s natural capacity, meaning they look and feel balanced while maintaining full function. Beyond this point, it’s about preserving your gains and keeping the tissue healthy for the long term.

Hybrid-Ultimate® Penis Filler Procedure

• Aseptic, single-entry technique: Mid-shaft entry under local anaesthetic using a blunt-tip cannula to access the full shaft with minimal tissue trauma.
• Proprietary Hybrid-Ultimate® filler blend: Combines instant structural volumisation with bio-stimulatory components to trigger collagen production.
• Real-time contouring: Product is layered and sculpted for symmetry and anatomical accuracy, with results visible immediately.
• Low downtime: Minimal bruising/swelling; normal activities resume in 24–48 hrs, sexual activity after ~14 days.
• Progressive collagen maturation: Firmness and definition increase over 6–8 weeks, with integration lasting up to 24 months. once collagen fibres form, these fibres can up to 3-5 years.

Surgery Limitations:

• Procedures like suspensory ligament release and implants often yield unpredictable, unnatural girth, with NO gain in erect length.
• High risk of complications: infection, nerve damage, deformity, erectile dysfunction and loss of sensation.
• Implants don’t adapt with aging and may generate psychological dissonance due to unnatural feel.

Hybrid-Ultimate® Filler Advantages:

• Non-surgical, scar-free, discreet.
• Combines HA-based immediate volume with biostimulatory filler for collagen stimulation over time.
• Results are natural, adaptable, reversible (for HA components), and maintain sensation and function.
• Evolves with the body and preserves long-term harmony.

The earliest you can come back for the second session is six weeks after the date of your first session. This is ample time for the penile tissues to stabilise, all residue swelling, bruising has subsided and the penis filler has fully integrated.

We recommend that all clients have their second session within three months of their first session.

Hybrid-Ultimate® is structured as a two-stage augmentation protocol to optimise tissue integration, minimise complication risk and enhance long-term stability of results. Delivering the total intended volume in a single sitting can exceed the compliance threshold of the penile fascia layers, increasing the risk of vascular compromise, product migration, and suboptimal neo-collagenesis. Staging the procedure allows progressive tissue expansion within physiological limits, supports uniform fibroblast activation and facilitates more controlled collagen deposition.

This approach yields a more consistent bio-mechanical profile, preserves neurovascular integrity and produces results that adapt with the patient’s native tissue over time.

In the UK, neither plastic surgery nor urology training includes penis filler techniques. The skill lies not in the job title, but in procedural volume, anatomical precision and product mastery.
At aiva wellness, this is our sole clinical focus. We perform a high volume of penis filler procedures, understand filler rheology and penile anatomy in depth and have extensive experience in collagen induction and long-term tissue behaviour. Our outcomes are documented across a wide range of anatomies, and we are consistently publishing in medical literature and research on penis filler, contributing to the global body of evidence in this field. Few surgeons or urologists perform these procedures at scale. For consistent, natural-looking results that respect both function and aesthetics, the most reliable choice is a specialist clinic dedicated entirely to aesthetic penis enhancement, exactly what we do at Aiva.

Circumcised clients often experience slightly smoother filler distribution, reduced swelling and faster recovery due to tighter tissue and less foreskin mobility. However, uncircumcised men also achieve excellent outcomes with appropriate technique adjustments, ensuring stable, natural-looking results in both cases.

The artistry lies in its ability to enhance girth, though it also creates a more pronounced, elongated appearance when flaccid. While erect length remains largely unchanged, the increased volume and structured contouring result in a visually more impressive profile.

N.B Penis Enlargement Surgery does NOT increase erect length either.

Mild bruising and swelling are the most common effects, subsiding within days. Following the curated aftercare protocol will ensure optimal healing and flawless results.

The HA component of Hybrid-Ultimate® penis filler can be adjusted or dissolved if required.

Immediate enhancement, girth expansion is visible instantly.

Mild swelling and bruising, common but temporary, resolving within a week. Ongoing refinement, the results continue to settle and integrate over the following weeks, ensuring a sculpted, natural aesthetic.

Following bespoke aftercare guidance, including massage techniques and optimal hygiene practices, is crucial for exceptional, enduring results.

Refined techniques ensure a virtually painless experience. The treatment is performed under meticulously administered local anaesthetic, eliminating discomfort. Post-procedure, some mild bruising and swelling may occur, but these dissipate within a few days, unveiling a seamless, natural enhancement.

Phase 1: Immediate Mechanical Expansion (Minutes → Hours) 

Hydraulic scaffolding and early settling 

As soon as the penis filler is injected into the sub-Dartos plane, it occupies a natural potential space between the penile fascia layers. The HA (Hyaluronic Acid) component provides immediate structure and projection, while the highly elastic Dartos fascia stretches circumferentially around it.

In the first few hours, the penis behaves as a dynamic, mobile structure, meaning the filler undergoes subtle redistribution along natural tissue planes. This is why minor unevenness or segmental fullness can temporarily appear; the tissue is still settling mechanically. This is also why a second session is always required to ensure optimal penis filler distribution along the shaft.

Phase 2: Biological Integration & Collagen Activation (Days → Months) 

From gel to living tissue 

Over the following days and weeks, a controlled biological response occurs. The HA acts as a temporary scaffold, maintaining volume and shape while allowing the PLLA (Poly-L-Lactic Acid) to exert its full potential.

During this period, the PLLA component activates fibroblasts, stimulating the production of new, well-organised collagen fibres. As the HA gradually resorbs, this new collagen progressively replaces it as the main load-bearing structure. This is when patients notice firmness becoming more natural, the tissue feeling less “gel-like,” and the volume stabilising.

Phase 3: Long-Term Tissue Maturation & Stability (6–24+ Months) 

Semi-permanent biological remodelling 

By the two-year mark, the HA has mostly been resorbed and the PLLA has completed its stimulatory role. What remains is your own natural collagen, fully integrated into the native penile tissue. At this stage, elasticity closely matches natural tissue, movement feels normal, and volume is maintained by living tissue rather than a foreign gel.

Key Point: This is the fundamental difference between Hybrid-Ultimate® and standard HA-only penis fillers. While standard fillers often lose their integrity and go very soft over time, Hybrid-Ultimate® results in smooth, firm, living tissue.

Why Two Sessions Matter

The Sub-dartos fascia plane is segmentally independent and contractile. No filler can override this natural biology in one session. A second session allows newly formed collagen to “lock in” architecture that cannot be forced mechanically. This results in improving uniformity, symmetry and long-term stability.

Preparation for penis enlargement with our specialised fillers is very straightforward:

• Hygiene: Please ensure the pubic hair is trimmed or removed so the area is clear. Shower and clean the area as part of your normal routine.
• Medication: Avoid alcohol and blood-thinning medications for 48 hours prior to treatment, unless advised otherwise by your doctor.
• Medical History: If you have had any previous surgical or non-surgical treatment involving the penis or testicles, please let us know beforehand.

There are no specific blood tests required before the procedure. Our goal is to make your penis filler journey as simple and stress-free as possible.

Yes, absolutely. You will experience no significant discomfort afterwards and can walk out of the clinic immediately.

Many of our clients have their penis filler procedure performed during a work break and are able to return to their office within the hour. There is no downtime involved; you are free to carry on with your day as normal, and even flying on the same day is permitted. We will guide you through a few specific aftercare points during your consultation to ensure the best possible results for your penis enlargement.
