How long do penis fillers really last ?

One of the most common questions men ask before having penis filler treatment is:
“How long will it last?”

The answer depends on the type of filler used, how your body metabolises it, and the skill of your injector.

1️⃣ The Average Duration

At Moorgate Andrology, we use hyaluronic acid (HA) fillers — the same type used in facial aesthetics.
On average, results last between 12 to 24 months.

However, some men retain volume for slightly more than 2 years, especially when top-up sessions are performed at 12 months.

2️⃣ Factors That Affect Longevity

Several factors influence how long penis fillers last:

• Metabolism: Faster metabolism = quicker breakdown of HA.

• Lifestyle: Smoking, intense exercise, and poor hydration can reduce longevity.

• Type of filler: Thicker HA gels tend to last longer.

• Amount used: More filler equals longer visible results.

3️⃣ Can the Results Be Maintained?

Yes — many men choose annual maintenance treatments to keep consistent girth and shape.
This helps the filler layer build gradually, leading to more natural and longer-lasting results over time.

4️⃣ What Happens When the Filler Wears Off?

If you decide not to have top-ups, the filler will gradually reabsorb into the body.
The penis will return to its natural size without any sudden change in shape or texture.

5️⃣ Are Permanent Fillers Better?

Permanent or semi-permanent fillers (like PMMA or PLLA) exist — but they come with higher complication risks.
At Moorgate Andrology, we only use reversible, safe, medical-grade HA fillers, which can be dissolved if required.

💬 Moorgate Andrology offers clinically proven HA fillers administered by GMC-registered surgeons and aesthetic doctors.
