"I’ve heard both Shrink and Onda lifting are good.

Which one should I choose?

Or can I get both together?"

As you become interested in lifting procedures, you may start wondering which one among the many options is right for you.

With so many different names and devices, you may be curious about what effects each one has and by what mechanism they are said to lift the face.

So today, let’s look together at Shrink, which can provide a strong lifting effect with ultrasound, and Onda lifting, which can provide tightening and fat-reduction effects with microwave energy.

I’ll explain in detail, from the principles and effects to whether it is okay to get them together.

Shrink vs. Onda

Shrink Lifting Principles and Effects

Shrink is a procedure that focuses high-intensity focused ultrasound (HIFU) into a single point to generate heat inside the skin.

The area reached by the ultrasound energy is the SMAS layer, or, in Korean terms, the "fascia layer."

Measured from the skin surface, it passes through the epidermis and dermis and reaches the membrane that surrounds the muscle. Although there are individual differences, this is usually about 4.5 mm below the skin.

You may wonder why energy is delivered inside the skin when what sags is the outside of the skin.

That is because as we age, if the fascia layer becomes loose and drops downward, the skin can quickly sag again even if you pull at the surface.

So when Shrink delivers heat-induced damage to this fascia layer, the body goes through a healing process, during which new collagen is produced and the skin is encouraged to become firmer.

These days, treatment is often performed with the upgraded device called Shrink Universe.

Compared with Shrink, the energy is delivered much more densely, and a pen-type handpiece has been added, making it possible to perform precise treatment on narrow, curved areas such as around the eyes and mouth.

Onda Lifting Principles and Effects

Now let’s talk about Onda lifting as well.

Onda lifting uses microwave energy. It is the same energy used by a microwave oven.

As the energy passes through, it does not affect the skin surface and instead concentrates heat only inside the skin.

That is why a major feature of the procedure is that the pain and stimulation felt during treatment are relatively low.

In addition, because it has a cooling system that continuously cools the skin surface, it is usually comfortable to receive even without anesthesia.

Looking at the effects, they differ depending on the type of handpiece used.

When treated with a 3 mm handpiece, the dermis is stimulated to encourage new collagen production, which can provide a skin-tightening effect.

When treated with a 7 mm handpiece, the fat layer is stimulated, helping to reduce unnecessary excess fat.

For the face, it is often used on areas such as the double chin or cheeks, and for the body, on areas such as the thighs or flanks.

Also, if you want both fat reduction and tightening effects, you can receive both, which makes it quite versatile.

Is It Okay to Get Them Together?

If you ask whether it is okay to get both together, I would say yes, it is possible.

That is because the energy used by the two procedures and the skin layers they act on are different.

Shrink reaches deep into the fascia layer of the skin and is strong at lifting the face’s structural framework. If you compare it to a house, it is similar to putting up the pillars.

On the other hand, Onda lifting can focus more on collagen regeneration and tightening in the dermis, which is closer to the skin, and it can also help define the lines by reducing excess fat.

You can combine Onda lifting to address areas with fat concerns such as the double chin or cheeks while performing deep lifting across the face with Shrink.

You could also use Shrink only on thin and sensitive areas such as around the eyes, and use Onda lifting to tighten broader areas overall.

Of course, there are many cases where one procedure alone is considered sufficient after taking into account facial shape, skin thickness, degree of sagging, amount of fat, and pain sensitivity, so the first step is to get an evaluation.

Today, we compared the principles and effects of Shrink and Onda lifting and also looked at what happens when they are used together.

I also explained combination treatments, but with lifting, more is not always better. It is important to plan strategically within a proper range that the skin can handle.

If you only look in the mirror by yourself, it is hard to know exactly where sagging begins, how much fat there is, or how thick the skin is.

So during a consultation, check whether they analyze and help you understand your skin well, and remember that getting treatment at such a place can further improve the results.
