What Dr. Emer did · PHALLONOX

Every procedure. In order.

01

Circumferential shaft injection 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
02

Glans augmentation PHALLONOX^™

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
03

Coronal ridge treatment PHALLONOX^™

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.
04

Post-treatment massage and shockwave therapy

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.”
Dr. Emer, in the film

Why patients fly in

What Dr. Emer does differently.

360-degree circumferential injection, not lateral width alone

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.

Suspensory ligament injections and Botox for length

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.

Superficial glans placement to prevent volume loss

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.

Volux for longer-lasting results

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.”

01Before
The starting point
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.
02The plan
What Dr. Emer decided to do
Hyaluronic acid filler placed 360 degrees for circumferential volume, with the head treated separately for balance and proportion.

03The session
In the room, in order
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.
- Inject the shaft
- Treat the suspensory ligament area
- Add volume to the head
- Massage and smooth
“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
04The result
What changed
“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
05What comes next
Recovery and what to expect
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.

The patient story

A reversible approach to size enhancement

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.

Why the head is treated differently

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.

Length came from treating the suspensory ligament area

Dr. Emer notes that length enhancement was not the original expectation of this procedure. 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 the video shows visible length increase compared to earlier sessions, and the dip at the base is gone, which indicates the length gain.

Downtime and maintenance

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.

Circumferential volume versus side injection

Some providers inject only from the sides to make the penis look wider from above, but Dr. Emer treats the area 360 degrees. This creates true circumferential volume, better sensation, and a more natural look.

The procedure shown in the video is called Phallonox, and it is performed in Dr. Emer's Manhattan and West Hollywood offices.

The treatment, explained

What is penile girth enhancement?

Also called penile length enhancement, hyaluronic acid penile augmentation, non-surgical penile enlargement, PHALLONOX^™ procedure, glans augmentation, penile filler, reversible penile enhancement.

What it is: PHALLONOX^™ is Dr. Emer's penile girth and length enhancement procedure using hyaluronic acid filler. Hyaluronic acid is a sugar-water substance that holds moisture and creates volume. The filler is placed 360 degrees around the shaft to increase circumference, and injections to the suspensory ligament area combined with Botox have produced measurable length gains in patients. The glans and coronal ridge are treated separately to maintain proportion and balance. This is not an FDA-approved procedure for this area; there are no clinical trials, and outcomes are based on physician experience.
How it works: Dr. Emer injects hyaluronic acid filler circumferentially around the penile shaft to create true volumetric expansion. The suspensory ligament area is injected and Botox is applied to that region, which has led to length gains. Volux, a higher G prime hyaluronic acid filler, is placed more superficially in the glans to prevent volume loss when pressure is applied. The corona is treated to balance the head with the shaft. The area is massaged immediately to blend the filler, and shockwave therapy is used post-treatment to smooth any temporary irregularities. Patients are advised to use daily Cialis or PT-141 peptide to enhance blood flow, which helps the hyaluronic acid hold more water and improves the result.
Who it is for: Men seeking reversible girth and length enhancement. Candidates include those who are disproportionate between the head and shaft naturally, those who have had shaft augmentation and want to balance the glans, and those who want measurable size increase without permanent implants or surgery. The procedure is appropriate for men who can abstain from sexual activity for one to two weeks following treatment to the glans. A consultation determines whether the anatomy and goals fit the procedure.
Recovery: 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 appear and typically resolve within a few days to a few weeks; shockwave therapy and massage accelerate smoothing. The result is visible immediately. Touch-up sessions are scheduled to maintain proportion over time. The specific recovery plan is set at consultation based on the areas treated and the volume placed.
When results show: Girth increase is visible immediately after injection. Length gains from suspensory ligament injections and Botox become measurable over the weeks following treatment. Volux, a higher G prime filler, lasts longer than standard hyaluronic acid fillers because the body must work harder to metabolize it. Hyaluronic acid holds water, and enhanced blood flow from daily Cialis or PT-141 peptide improves the result. Touch-up sessions maintain proportion as the body gradually metabolizes the filler. Because this is not an FDA-approved procedure and there are no clinical trials, duration and outcomes are based on physician experience and individual patient factors.

About Dr. Emer Schedule Consultation

EMER METHOD^™×RECODEX^™

The head is like a sponge

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.

Higher G prime lasts longer

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.

Blood flow enhances the result

Daily Cialis or PT-141 peptide improves blood flow to the area, which helps the hyaluronic acid hold more water and enhances the result.

Circumferential volume is better

Treating the area 360 degrees creates true circumferential volume, better sensation, and a more natural look than side-only injection.

Asked plainly, answered plainly

What men ask before they book.

Is this procedure FDA approved?+

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.

Is the result reversible?+

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.

How much girth and length can I expect?+

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.

What is the downtime?+

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.

Why do you treat the head and the corona separately?+

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.

How long does the result last?+

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.

What is the difference between 360-degree injection and side-only injection?+

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.

Can I enhance the result after treatment?+

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.
