We are proud to have brought this innovation to market, offering outcomes that simply cannot be matched elsewhere.
What Is Penis Enlargement?
Penis enlargement refers to treatments that improve the size, shape, and overall appearance of the penis. Traditionally achieved through surgery, enlargement can now ( for many years now) be performed with safe, non-surgical methods such as penis fillers. The results of non-surgical Penis Filler, especially with our CDS™ penis enlargement techniques, completely out performs penis enlargement surgery in all facets. Our procedure can significantly increase the girth of your penis in the flaccid and erect state. It also significantly increases the length and hang of the penis in the flaccid state.
At Aiva Wellness, we prioritise precision, safety, and natural results. Our unique approach ensures each client receives a treatment tailored to their body and goals.
Penis Enlargement vs Surgery
Men exploring penis enlargement surgery often face risks including scarring, loss of sensation, and lengthy downtime. While surgery can create permanent changes, it also carries irreversible risks, and NOT permanent results. Many believe that penis enlargement surgery can increase the legnth of the erect penis. This is simply NOT true and is false. Hence why the non-surgical alternative being penis filler is the superior option in terms of efficacy and safety.
Penis Fillers offer:
-
Non-surgical, minimally invasive treatment
-
Immediate results with natural feel
-
Reversible and adjustable outcomes
-
3–5 years of results with our Hybrid-Ultimate® Penis Filler protocol. (This means at the 3-5 year mark you will still retain circa 50-60% of the volume. You will NOT be starting from 0 again. Which is why you only need small volume top ups to keep you at 100% gain or go larger if you wish.

This pioneering approach combines densely cross linked hyaluronic acid with collagen-stimulating fillers- Poly-L Lactic Acid (PLLA) for results that improve over time.
Benefits include:
-
Noticeable girth increase
-
Safe, medically validated procedure
-
Long-lasting results (up to 5 years)
-
Performed only by GMC-registered doctors
Hybrid-Ultimate is a bio-stimulatory filler designed to stimulate neo-collagenesis,with initial collagen deposition typically observed at 6–8 weeks and continued maturation 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. This is what makes Hybrid-ultimate Penis Filler® superior the standard Hyaluronic Acid only dermal fillers for penis enlargement.

How Big Can I Get?
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® Penis Filler, 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. Altough clients can go larger than this if they desire. However this will take multiple sessions over a 2-3 year period.
Hybrid-Ultimate Penis Filler Procedure
Below is a summary of our penis filler and penis enlargement protocol:
-
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.
Two Sessions of Penis Filler Are Required For Best Results
Hybrid-Ultimate® Penis Filler 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.
It also allows us to sculpt any areas which need further blending along the penile shaft to get as close to a 100% perfectly smooth and round cylinder.

Before & After Penis Fillers: What to Expect
Clients typically notice significant results immediately after treatment, with final improvements as collagen stimulation takes effect, around 4-6 weeks. The Collagen stimulation process is crucial because this is what causes the firm, smooth, stiff result with longevity that is desired post a penis filler augmentation.
At Aiva Wellness, we provide confidential before-and-after guidance, realistic expectations, and private consultations.
