Penis Filler FAQ's

What is Hybrid-Ultimate Penis Filler, and what type of filler is used?

The Hybrid-Ultimate Penis Filler is a proprietary, non-surgical treatment designed for penile enhancement. We utilize Hyaluronic Acid (HA) filler—a biocompatible gel substance naturally found in the body—to safely and effectively increase girth. The "Hybrid-Ultimate" protocol refers to our unique, multi-stage injection technique that ensures a smooth, natural look and feel, maximizing product integration and longevity.

How much does Hybrid-Ultimate Penis Filler cost?

The cost of the Hybrid-Ultimate Penis Filler procedure is determined by the total volume (number of syringes) required to achieve your desired girth increase, as well as the unique two-stage protocol.

We offer comprehensive package pricing, starting at [Insert Starting Price Here, e.g., $4,500] for the foundational first session. This price typically includes the cost of the filler, the practitioner's fee, and all necessary follow-up care for the first stage.

Since the goal is a customized, natural result, we require a consultation to determine the exact volume needed for your specific anatomy and aesthetic goals. We also offer [mention any financing or payment plans, e.g., financing options] to make the treatment more accessible.

How long do the results of the Hybrid-Ultimate Filler last?

The results of the Hybrid-Ultimate Filler are long-lasting, typically enduring between 18 to 24 months for most patients.

We use high-quality, stabilized Hyaluronic Acid (HA) filler, which the body naturally and gradually metabolizes over time. Longevity is influenced by the amount of filler used and your individual metabolism.

To maintain your desired girth, we recommend a maintenance session (often requiring less product than the initial treatment) at the 12- to 18-month mark. We advise patients not to wait for the filler to completely dissolve before coming in for a touch-up.

How much girth increase can I expect from the treatment?

The typical patient can expect a girth increase of 30% to 50% in the relaxed state, which is generally equivalent to a $\frac{1}{2}$ inch to $1 \frac{1}{2}$ inches in circumference, depending on the volume of filler used and the natural elasticity of your tissue. Since the treatment is performed across two sessions, we can customize the volume during the second stage to ensure you achieve your desired aesthetic result while maintaining a natural, proportional look.

What is The Treatment Process?

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.
Penis Filler vs Penis Enlargement Surgery

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.
What is the downtime, and when can I resume sexual activity?

The Hybrid-Ultimate Penis Filler treatment is minimally invasive, resulting in very little downtime.

  • General Downtime: You can usually return to work and light, non-strenuous daily activities within 24 hours.
  • Exercise: Avoid strenuous exercise, heavy lifting, and activities that cause excessive sweating for 3–5 days.
  • Sexual Activity: To prevent filler migration and ensure optimal, smooth results, you must abstain from all sexual activity, including intercourse and masturbation, for a minimum of 2 weeks (14 days). Your practitioner may recommend up to 4 weeks depending on your individual healing process and the volume of filler used.
Who Should Perform My Penis Filler: Surgeon or Cosmetic Doctor?

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 vs Uncircumcised

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.

Will the Hybrid-Ultimate Filler increase penis length?

No, penile fillers are designed specifically for girth enhancement, not length. The filler material is injected into the layers just beneath the skin and fat pad, which increases circumference. While some patients report a slight increase in flaccid length due to the weight of the filler, the primary and guaranteed result of the Hybrid-Ultimate treatment is a noticeable increase in girth. If length is your primary concern, we can discuss surgical options.

Are there any potential side effects or risks of penis filler?

As with any injectable treatment, there are potential side effects, though the procedure is considered very safe when performed by an experienced professional. Common, temporary side effects include minor swelling, bruising, and tenderness at the injection sites, which typically resolve within a few days. Rare but serious risks include infection or vascular compromise, which is why we strictly adhere to the highest safety protocols and use only fully reversible HA fillers.

Can The Filler Be Reversed Or Adjusted?

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

What Should I Expect Post Treatment?

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.

Is the procedure painful?

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.
