From the filmed session
What Dr. Emer did · PHALLONOX
Hyaluronic acid filler placed 360 degrees around the penile shaft to create true circumferential volume, not just lateral width. The suspensory ligament area is injected and Botox is applied to that region, which has produced measurable length gains in patients as the procedure evolved.
“What we're doing is it's simulating it 360°. So, with sensation, it's better. And overall, it's completely volumized. That's more of a natural look.”
Dr. Emer, in the film
Volux, a higher G prime hyaluronic acid filler, is placed more superficially in the glans to prevent volume loss under pressure. The glans absorbs significant hyaluronic acid like a sponge; superficial placement maintains volume when compressed.
“The head is like a sponge. So, think about a sponge. It can absorb a ton of water, which is basically what the head will do with hyaluronic acid.”
Dr. Emer, in the film
The corona is treated to balance the head with the shaft and maintain proportion. This area is critical for sensation and for visual balance between the augmented shaft and glans.
Immediate massage blends the filler and ensures even distribution. Shockwave therapy and continued massage smooth temporary lumps or bumps that may appear in the days or weeks following treatment.
“Sometimes you'll have like a little like a lump or a bump for a couple days or a few weeks. What actually improves it a lot is shockwave therapy and massage.”

Why patients fly in
Dr. Emer injects hyaluronic acid around the entire circumference of the shaft, creating true volumetric expansion and better sensation, rather than injecting only the sides to create the appearance of width from above.
As Dr. Emer began injecting the suspensory ligament area and applying Botox to that region, patients gained measurable length in addition to girth. Length enhancement was not the original expectation of the procedure.
Dr. Emer places filler more superficially in the glans to avoid losing volume when pressure is applied, understanding that the glans behaves like a sponge and will release water if the filler is placed too deep.
Dr. Emer uses Volux, a higher G prime hyaluronic acid filler, which the body must work harder to break down, resulting in longer duration than standard hyaluronic acid fillers.
“When something has a higher G prime, like Volux, per se, is more likely that this type of filler would actually last longer over time because of the fact that your body needs to work harder to break it down.”
Dr. Emer films procedures in real time so results can be verified, distinguishing his work from claims made with AI-generated content, Photoshop or before-and-after images that cannot be authenticated.
“That's why I'm showing you guys live right now so you could see it in real life.”
THE THINKING BEHIND THE TREATMENT
Follow Dr. Emer’s approach through the stages described in this case.
Back to the video ↗This patient has had previous treatments and is now adding volume to the head using Volux, a thicker hyaluronic acid filler.
The patient shows visible length increase compared to earlier sessions, and the dip at the base is gone, which indicates the length gain. Dr. Emer explains that length enhancement was not the original expectation of this procedure, but as he and other physicians started injecting the suspensory ligament area and using Botox in that region, patients began gaining measurable length in addition to girth.
Hyaluronic acid filler placed 360 degrees for circumferential volume, with the head treated separately for balance and proportion.

He treats the head and the corona to balance the head with the shaft and maintain proportion. The result is visible immediately, and the patient is instructed to avoid sex or masturbation for one to two weeks to allow the filler to settle.
“So you could see, hold on. I know you guys haven't seen HA that often. But look, it already it's so much bigger.”DR. JASON EMER · FROM THE VIDEO
“So significantly better. The head is definitely bigger and it just much longer. And also you can see the dip at the base here is gone now which means we got length.”DR. JASON EMER · FROM THE VIDEO
Patients are instructed to avoid sex or masturbation for one to two weeks after treatment to the head. Dr. Emer recommends daily Cialis or PT-141 peptide to improve blood flow to the area, which helps the hyaluronic acid hold more water and enhances the result.
Volux is a higher G prime filler, meaning the body has to work harder to break it down, so it lasts longer than standard hyaluronic acid fillers. Touch-up sessions are used to balance the sides and maintain proportion as the top of the head tends to store more hyaluronic acid over time.
Girth and length, built with hyaluronic acid / Patient story
This patient has had previous treatments and is now adding volume to the head using Volux, a thicker hyaluronic acid filler.
The patient shows visible length increase compared to earlier sessions, and the dip at the base is gone, which indicates the length gain. Dr. Emer explains that length enhancement was not the original expectation of this procedure, but as he and other physicians started injecting the suspensory ligament area and using Botox in that region, patients began gaining measurable length in addition to girth.

The patient in this video has had previous treatments and is now adding volume to the head of the penis using Volux, a thicker hyaluronic acid filler. Hyaluronic acid is a sugar water substance that the body metabolizes over time, which makes it reversible if needed.
Dr. Emer explains that this is not an FDA approved procedure for this area. There are no clinical trials, so outcomes are based on physician experience. He emphasizes the importance of finding a provider whose work you can verify through live video and patient results, not just claims made online.
The head of the penis is like a sponge: it can absorb a significant amount of hyaluronic acid. Dr. Emer places the filler more superficially to avoid losing volume when pressure is applied, the way a sponge loses water when squeezed.
He treats the corona, the ridge around the head, to balance the head with the shaft and maintain proportion. This area can be bloodier and may have temporary lumps or bumps for a couple of days to a few weeks. Shockwave therapy and massage help smooth the result.
How a session is built
Hyaluronic acid filler placed 360 degrees for circumferential volume, with the head treated separately for balance and proportion.
Hyaluronic acid filler is placed 360 degrees around the shaft to create true circumferential volume, not just width from above.
Injections to the suspensory ligament area and Botox in that region have led to measurable length gains in patients.
Volux, a thicker hyaluronic acid filler, is placed more superficially in the head to avoid losing volume when pressure is applied. The corona is treated to balance the head with the shaft.
Dr. Emer massages the area to blend the filler and ensure even distribution. Shockwave therapy and massage help smooth any temporary lumps or bumps.

Why Dr. Emer
This is not an FDA approved procedure for this area. There are no clinical trials. Outcomes are based on physician experience.
Dr. Emer has performed this procedure on patients from around the world and documents his work in live video so results can be verified. He emphasizes the importance of finding a provider whose work you can see in real time, not just claims made online or through AI-generated content.
The Phallonox procedure uses hyaluronic acid filler, which is reversible if needed. Dr. Emer explains every step of the process, from why the head is treated differently than the shaft to why circumferential volume creates better sensation and a more natural result.
The head of the penis can absorb a significant amount of hyaluronic acid. Dr. Emer places the filler more superficially to avoid losing volume when pressure is applied.
Volux is a higher G prime filler, meaning the body has to work harder to break it down, so it lasts longer than standard hyaluronic acid fillers.
Daily Cialis or PT-141 peptide improves blood flow to the area, which helps the hyaluronic acid hold more water and enhances the result.
Treating the area 360 degrees creates true circumferential volume, better sensation, and a more natural look than side-only injection.
Asked plainly, answered plainly
No. There are no FDA-approved fillers for penile augmentation and no clinical trials for this use. Outcomes are based on physician experience. Dr. Emer documents his work in live video so results can be verified, and he emphasizes finding a provider whose work you can see in real time rather than relying on claims that may be AI-generated or digitally altered.
Yes. Hyaluronic acid is a substance the body metabolizes over time, and it can be dissolved with hyaluronidase if needed. This reversibility is one reason Dr. Emer uses hyaluronic acid for patients who want a non-permanent approach to size enhancement.
The amount of girth increase depends on the volume of filler placed circumferentially around the shaft. Length gains from suspensory ligament injections and Botox are measurable but were not the original expectation of the procedure; Dr. Emer observed length increase as he refined the technique. Individual anatomy, the volume used and the number of sessions determine the result. Specific expectations are discussed at consultation.
One to two weeks of no sex or masturbation after treatment to the glans to allow the filler to settle. Temporary lumps or bumps may last a few days to a few weeks and are smoothed with shockwave therapy and massage. The result is visible immediately, and most men return to normal activity within the recovery window.
The glans and corona are treated to balance the head with the augmented shaft and maintain proportion. The glans absorbs hyaluronic acid like a sponge, and Dr. Emer places the filler more superficially to prevent volume loss when pressure is applied. The corona is important for sensation and for visual balance between the head and the shaft.
Volux is a higher G prime filler that lasts longer than standard hyaluronic acid fillers because the body must work harder to break it down. The body gradually metabolizes hyaluronic acid over time. Touch-up sessions are used to maintain proportion and volume. Because there are no clinical trials for this procedure, duration is based on physician experience and varies by individual.
Injecting only the sides creates the appearance of width from above but does not increase circumferential volume. Dr. Emer injects 360 degrees around the shaft to create true volumetric expansion, which provides better sensation and a more natural look. Circumferential treatment requires more filler but produces a result that is balanced from every angle.
Yes. Dr. Emer recommends daily Cialis or PT-141 peptide to improve blood flow to the area, which helps the hyaluronic acid hold more water and enhances the result. Shockwave therapy and massage smooth any temporary irregularities and improve the final appearance.
