Hello, I am Toshiyuki Saiga, Director of Bianca Clinic Ginza Clinic.

Many people are interested in breast augmentation, but when they actually look into it, they find that there are so many different types that they are confused and wonder, “Which one is right for me after all?” Many people are confused. In fact, many people come to the clinic wondering if they should use fat, silicone, or both. However, there are only three main types of breast augmentation. Today, I will explain all three as clearly as possible from a physician's point of view.

There are three main types of breast augmentation!

Although there are technical differences when looking at breast augmentation methods in detail, there are three classifications

  • Fat Transfer Breast Augmentation
  • Silicon bag breast augmentation
  • Hybrid breast augmentation (fat injection + silicone implant)

Once you understand how to “distinguish” between these three types, there is no need to be confused. First, let's understand the characteristics of each.

Fat Injection Breast Augmentation|If you choose by texture, this is the one to choose!

This method involves harvesting one's own fat and carefully removing the unwanted portions before injecting it into the breasts.

<Fat Injection Breast Augmentation Features

  • The touch is just natural.
  • “Slimming” and “breast enhancement” can be achieved at the same time.
  • Even the movement of the chest is natural

Since fat is a living cell, when injected, it becomes an integral part of the body. The result is simply "natural. There is no better texture than this. Fat is often harvested from the abdomen and thighs, which can also be used for partial weight loss. Among fat injection breast augmentation, Bianca introduces Condense Rich Fat Injection Breast Augmentation. The collected fat is carefully separated from impurities, aging cells, and water using special equipment, and only carefully selected condense rich fat (CRF) is used. It is characterized by the ease of achieving a shape that is more easily blended in.

Silicon bag breast augmentation|If you want a reliable size increase!

Silicon bag breast augmentation is a procedure in which silicone implants are placed in the breast to create volume.

<Features of silicone bag breast implants

  • Solid size increase is expected.
  • Easy to control the number of cups
  • Easy to create cleavage and upper breast firmness

The position of the silicone bag is adjusted according to your wishes and the condition of your breasts. If you want to increase the size of your breasts by 2 to 3 cups or more, silicone implant breast augmentation is the most realistic way to achieve this.

The basic method of silicone bag breast augmentation is to make a large incision in the breast, but Bianca has also introduced the fourth generation of silicone bag breast augmentation, Preserve. The scar is only 2.5 cm in diameter, and the procedure is performed with the utmost consideration given to the effects on the tissue. This is recommended for those who want to have larger breasts but were concerned about the downtime and could not make a decision.

Hybrid Breast Augmentation (Fat Injection + Silicon Bag)|For those who cannot compromise on size and texture

Hybrid breast augmentation is a procedure that combines the “firmness” of silicone bag breast augmentation with the "natural softness" of condense rich fat injection breast augmentation. While silicone bag breast augmentation can certainly increase volume, its weakness is that it tends to feel artificial to the touch. On the other hand, fat injections have a very natural texture, but it is difficult to significantly increase the size of the breasts. Hybrid breast augmentation is a method that compensates for these two weaknesses, aiming to achieve both "volume" in appearance and "naturalness" when touched.

<Hybrid Breast Augmentation Features

  • Much more natural to the touch
  • “Combination of ”size“ and ”softness
  • Easy to adjust for décolleté bumps and left-right differences

I want them to be bigger, but I don't want them to be unnatural. Hybrid breast augmentation is the easiest way to fulfill such “selfish” wishes.

Hyaluronic Acid Breast Augmentation|Why it is easy but basically not recommended

Incidentally, there is also a method called “hyaluronic acid breast augmentation,” in which hyaluronic acid is injected into the breasts to increase volume. Because it can be done by injection alone, without the use of a scalpel, downtime is short, and it is easily recognized as a "simple breast augmentation" procedure.

However, the effect is temporary, and the body will eventually absorb it, so periodic reapplication is necessary. Another disadvantage is that a reasonable amount of hyaluronic acid is required to achieve a firm volume, and the cost per session tends to be relatively high. Furthermore, some foreign countries have banned hyaluronic acid breast augmentation due to safety concerns. For these reasons, Bianca does not recommend hyaluronic acid breast augmentation.

How to choose the type of breast augmentation|Who is suitable for fat injection breast augmentation?

Fat injectable breast augmentation is the perfect method for those who want to prioritize “naturalness” and “softness” in any way. Since your own fat is transplanted, you are less likely to feel the discomfort of artificial breasts in the way they feel and sway, and you can achieve the look and feel of the breasts that you originally had.

  • I like the natural finish.
  • I want to fluff back the postpartum shrivel.
  • I want to be slim but not “overdone”.
  • I want to achieve slimming together.

It is possible to increase the size by about one to two cups. The overall silhouette will change to a more feminine appearance as the fat naturally thickens.

On the other hand, there is a limit to the amount of fat that can be injected, making it unsuitable for those who have a small amount of fat to begin with or for those who want to "make it bigger for sure. It is also important to understand that not all of the injected fat will be retained, but 20-50% will be absorbed, so the final size will be smaller than immediately after the surgery.

In addition, the precision of the “processing technology” is extremely important to maximize the fat retention rate. Excess water and impurities are removed, and only living fat is delivered to the breast. The quality of this process makes the difference in the final result.

How to choose the type of breast augmentation|Who is suitable for silicon bag breast augmentation?

Silicon bag breast augmentation is a breast augmentation technique suitable for those who want to increase the size of their breasts without fail. The most attractive feature of this technique is that it allows the surgeon to control the volume and shape of the breasts in a way that fat cannot do.

>Silicon bag breast augmentation

  • I want to raise more than 2 to 3 cups firmly.
  • I want to strengthen the firmness of my upper chest.
  • I'm skinny and fat injections alone are not enough.
  • Anyway, I want to make the shape clear.

Implants are available in a wide variety of sizes and shapes, and the results are easily predictable. Another major advantage of silicone bags is that changes can be felt immediately after surgery.

A common concern is, "If someone touches me, won't the firmness immediately give me away?" is one of the most common concerns.

Recently, silicone bags that change shape with movement and are less likely to form a capsule have been introduced, but no matter how advanced they are, there are limits to what can be achieved with artificial products. However, no matter how advanced they may be, they still have their limitations because they are artificial. For those who “don't want to be exposed” and "want a natural feel," fat injections or hybrid breast augmentation may be more suitable. It is also important to understand that there is a risk of bag breakage, which is very rare, and that maintenance such as replacement may be necessary in the future.

How to choose the type of breast augmentation|Who is suitable for hybrid breast augmentation?

Hybrid breast augmentation is the easiest of the three to achieve. By combining the reliable volume of silicone implants with the naturalness of fat injections, the degree of freedom of the finished result is dramatically increased.

<ハイブリッド豊胸がおすすめなのはこんな人!>

  • I don't want to give up either size or softness.
  • I'm skinny but want natural breast augmentation
  • Concerned about décolleté bumps and left-right differences
  • Avoid unnatural tension or a “baggy” look.

By creating a firm base volume with silicone implants and then softly layering fat on top, it is possible to approach a state of "natural look and feel. The strength of hybrids is that they are easy to balance by adding fat, even for those who are thin or whose upper breasts appear shaved, and it is also easy to adjust the left-right difference and fine-tune the line.

Many people also find the fact that liposuction allows them to lose weight in areas of concern at the same time, which is attractive.

Consult Bianca Clinic to find the type of breast augmentation that is right for you!

Breast augmentation can be divided into three main types: fat injections, silicone bags, and hybrids. The best breast augmentation method depends on what you want to achieve, such as “I want it natural,” "I want it to be large," and "I want it to be comfortable to the touch. The important thing is not to choose "which one is the best," but to choose the method that best fits your body shape, breast condition, and ideals.

During the consultation, we will ask you about your wishes while checking the condition of your breasts and suggest the best option, so please feel free to contact us if you are not sure.
