How Long Do Penile Fillers Last? (Concrete Answer)

The lasting effects of penile fillers have been an interesting topic of discussion in the community of penis enlargement and augmentation.

I’m often asked how long do penile fillers last, and it’s a completely understandable question. Men want to know how long a positive change will last so they can prepare for the following steps.

Since the majority of doctors tip-toe around this topic, I’ve taken it upon myself to give you a clear, straight, non-BS answer regarding this question.

Let’s get right into it.

Penile Fillers 101

Penile fillers are a form of cosmetic treatment aimed towards enhancing the girth, or sometimes the length, of the penis.

This is done by injecting certain substances into some areas of the penis. The areas of injection depend on the penis filler we’re talking about.

Some of the most popular penile fillers used today are:

  • Hyaluronic Acid Fillers
  • Autologous Fat Transfer Fillers
  • PMMA Microspheres
  • Collagen-Stimulating Fillers

Each of these types of penis fillers has its own advantages and disadvantages, and depending on what you’re looking for, the optimal choice may vary from person to person.

I always say to people who come to me for information on this topic that they should thoroughly research all available options before they make a decision. This prevents men from creating unrealistic expectations and, eventually, dissatisfaction with the end result.

Factors Affecting the Longevity of Penile Fillers

Each type of penis filler lasts for a different amount of time. The answer to how long do penile dermal fillers last consists of a plethora of factors that need to be taken into consideration when discussing the longevity of said fillers, and each one is equally important.

Filler Type

The first factor is the type of filler a doctor uses to enhance a penis. For example, hyaluronic acid has the shortest lifespan, and for those who are looking for non-permanent solutions, this is a go-to.

Fat transfers, on the other hand, are a different story. Your body’s ability to reabsorb the injected fat plays a crucial role in the longevity aspect. For some, this is a much slower process, but for others, it’s much faster than anticipated.

PMMA (polymethylmethacrylate) microspheres and similar synthetic fillers are in the category of semi-permanent filler types. Unlike fat, these fillers aren’t absorbed by the body, so their longevity is much better than the above mentioned alternatives.

Lastly, collagen-stimulating fillers are the only permanent option among fillers for penile enlargement. By injecting these, you stimulate the creation of collagen tissue, which is permanent. So, the only factor that is important here is how many treatments you have, each one adding more volume.

Individual Metabolism & Lifestyle

A patient’s metabolism plays a significant role in how long penile fillers last. Men with faster metabolisms can and will metabolize certain filler substances quicker, which consequentially, leads to shorter durations of the desired outcome.

Lifestyle also has a lot to do with the longevity of said fillers. Sexual and other activities regarding the pelvic region (such as working out) heavily impact the amount of time a penile filler will last.

Other lifestyle choices like smoking, drinking, and eating patterns also have an impact on the longevity of penis fillers.

Although the severity of the impact may differ, the impact of these activities itself is inevitable.

Type-Specific Longevity of Penile Fillers

I have to emphasize that the information I’m about to share with you is not set in stone. Every human body is different, and it reacts to fillers in different ways. So, please take that into consideration when asking yourself how long do penile fillers last.

Hyaluronic acid penile fillers typically last between 12 and 24 months. Some people claim they lost a significant amount of gain in just 6-8 months, which is not impossible.

With autologous fat transfers, it’s hard to pinpoint the longevity. The person’s metabolic system plays a huge role in this, so there aren’t any hard-set rules for how long these injections last. But, I can tell you that you can expect 30%-50% of the injected fat to be reabsorbed by the body just a couple of months (3-50) after the procedure

PMMA Microspheres are, on the other hand, considered a semi-permanent solution. Their effects last for years, and the area in which they’re injected never returns to its original form. All you can lose is a percentage of the gained volume.

Lastly, collagen-stimulating injections. These injections are a permanent solution to all your troubles. The effects are long-lasting, and you won’t notice any considerable loss in the volume you’ve gained.

A perfect example of this kind of procedure is what we call do here at Prometheus: a minimally-invasive, non-surgical procedure that consists of injecting our proprietary filler made of FDA-approved compnents underneath the skin of a penis to stimulate forming of collagen tissue. This collagen replaces the filler over a few weeks and becomes permanent, allowing the client to gain both girth and length.

For all interested parties, I suggest you swing by our clinic. Make an appointment, have a talk with me, and let’s set and achieve your goals together. It’s time you redefine the levels of self-confidence you think you can achieve in only a few hours!
