The concern with Aquafilling is that even when there are no symptoms now, complications may still develop later.

Aquafilling is an injectable breast filler made from a gel consisting mainly of saline and a small amount of polyacrylamide hydrogel (PAAG), a synthetic polymer.

It began to be used for breast augmentation in the 1990s and was once promoted as a water-rich, body-friendly filler with results said to last about 3-5 years.

In recent years, however, medical societies and regulatory authorities in multiple countries have raised safety concerns.

The Japan Society of Aesthetic Plastic Surgery (JSAPS) has officially stated that Aquafilling is not recommended for breast augmentation, citing reported complications such as breast swelling, redness, nipple protrusion, tenderness or pain, breast asymmetry, and breast deformity.

The U.S. Food and Drug Administration (FDA) has not approved injectable fillers for breast augmentation, and the British Association of Aesthetic Plastic Surgeons (BAAPS) has also warned about the risks of breast filler procedures.

Given these concerns from experts in Japan and overseas, MYCLI does not consider Aquafilling breast augmentation to be a safe procedure.

We recommend early removal even if you have no symptoms

If you already have Aquafilling in your breasts, it is important not to assume everything is fine simply because you currently have no symptoms.

With Aquafilling, problems can arise later even when there is no issue at present.

There are reported cases in which patients had no immediate problems after injection, but developed sudden infection or inflammation years later, sometimes triggered by breastfeeding.

If the gel migrates or spreads over time, removal may become more difficult later.

Removing as much Aquafilling as possible, as early as possible, may help lower the risk of future complications.

We particularly recommend considering removal in advance for patients who are planning pregnancy or childbirth, or who may breastfeed in the future, to help prevent serious problems during lactation.

Even if you do not plan to breastfeed, removing a potentially problematic foreign material can help reduce future anxiety.

POINT

Removal under ultrasound guidance

Minimal, discreet incisions for removal

Optional breast enhancement using another method

Precise removal under ultrasound guidance

Simply making an incision and squeezing blindly is not an appropriate way to remove injected foreign material.

We remove the material while confirming in real time where it is located and how it has spread.

At MYCLI, we use ultrasound, a non-invasive imaging method that does not use radiation, to check the location of the foreign material in real time during the procedure.

Rather than relying on feeling alone, we identify the material as precisely as possible and remove it with the goal of minimizing any remaining residue.

Minimal, discreet incisions for removal

During removal surgery, we keep the incision as small as possible and take care to place and close it so the scar is discreet.
At some other clinics, patients are told that removing this material requires a large incision of 5 to 6 cm.

At MYCLI, we generally use the existing entry points from the original Aquafilling injection — small openings in the armpit or under the breast — and carry out the removal through an incision of just a few millimeters.

By drawing on liposuction techniques, we can remove the material without adding extra scars.
We take great care to keep any new scarring from becoming noticeable after surgery.

(If the Aquafilling has become infected, removal may instead require an incision of a few centimeters so that the material can be cleared out by hand.)

Optional breast re-augmentation after removal

Many patients tell us they worry their breasts will look deflated once the Aquafilling is removed.

Removing the Aquafilling does cause a temporary loss of volume — but there’s no need to worry.
Once enough time has passed after removal, the breasts can be re-augmented using a different, safer method.

At MYCLI, we remove the material completely, let your body recover fully, and then re-augment the breasts whenever you feel ready.

Because the tissue is fragile right after removal, we generally recommend waiting at least one month before the next procedure.

Options for re-augmentation include fat transfer using your own fat, silicone implant augmentation, and a hybrid approach that combines fat transfer with a silicone implant.
