Penis fillers are one of the fastest-growing treatments for men looking to improve their confidence and sexual wellbeing. Using advanced hyaluronic acid (HA) injections, this non-surgical procedure offers an immediate increase in girth with minimal downtime.
We introduced penis fillers to the UK over 10 years ago now. Since then it has become extremely popular as a walk in walk out treatment to increase penis size with little downtime
But how do penis fillers actually work, how long do they last, and are they the right choice for you? In this guide, we’ll cover everything you need to know about penis fillers in the UK, from cost and safety to results and alternatives.
Penis fillers are injections of hyaluronic acid — a naturally occurring substance found in the body — placed just beneath the skin of the penis. The gel-like filler increases thickness (girth) and can subtly improve symmetry.
Unlike surgery, fillers do not involve incisions or downtime. The procedure usually takes under an hour and is performed in a clinic setting by qualified Urologists who are experts in genital medicine and surgery
Immediate results – girth enhancement is visible straight after treatment.
Non-surgical – no general anaesthetic, no hospital stay.
Reversible – fillers can be dissolved if needed.
Customisable – volume can be adjusted across sessions for gradual change, and the size of the penis.
Confidence boost – many men report higher self-esteem and sexual satisfaction.
Consultation – A urologist discusses your goals, medical history, and whether fillers are right for you.
Preparation – Local anaesthetic injections ensure the procedure is comfortable. ( not just cream as some clinics use )
Injection – Hyaluronic acid filler is carefully placed beneath the penile skin following the numbing of the penis
Aftercare – You’ll be given instructions on healing and avoiding certain activities for a short period.
The whole process typically takes 30 minutes depending on the volume injected
On average, penis fillers last 12–24 months before gradually dissolving. Longevity depends on:
The amount of filler used. The penis should be injected with deep tissue hyaluronic acid for longevity
Your metabolism and lifestyle. Absorption rates are accurate but vary a little bit between patients since it is your body that is breaking it down. Hyper-absorption is rare, but it can happen.
The type of filler chosen. Avoid collagen stimulating injections, so called " hybrid" formulas since these can be very problematic if you experience lumps or bumps
Some men choose to book top-up treatments every 12 months to maintain results. This will depend on the penis enlargement filler you choose
Costs vary depending on how much filler is used.
Average cost: £120–£300 per mL
Typical treatment: 10 to 20 ml per session first time, top treatments require about half the first amount
Total cost: £1,200–£6,000 per session
It’s important to remember fillers are temporary. Over several years, repeat treatments may cost more than one-time penis enlargement surgery.
Penis filler is a safe treatment when performed by experienced medical professionals. At Moorgate Andrology, all procedures are carried out by GMC-registered urologists, reducing risks significantly. We have done the research over the years since we started to perfect the technique and ensure safe and predictable treatments
Potential side effects may include:
Temporary swelling or bruising. Less so nowadays since we introduced cannula led treatments instead of needles.
Minor discomfort at the injection site.
Rare complications such as infection or unevenness. Infection is very rare and we have minimised lumps and bumps by using cannulas. They can still occur though but are treatable.
Choosing a clinic with specialist medical expertise is crucial to minimise risks. Many facial filler practitioners are now injecting the penis with filler with little knowledge or experience of the anatomy and injection of the penis
While fillers are ideal for men seeking a quick, reversible option, they are not permanent. Surgery, on the other hand, provides a long-term solution.
Fillers – Quick, temporary, 12–24 months, repeat costs.
Surgery – Permanent results, one-time investment, more recovery time.
At Moorgate, we offer both treatments, so you get honest advice based on your needs. Some practitioners and penis filler clinics present a distorted and biased view, which is unhelpful for patients when trying to decide what is right for them
