What Is the Difference Between the Effects?

"I don’t really know what’s different between Eye Thermage and Eye Ulthera."

If you look into treatments for the eye area, Eye Thermage and Eye Ulthera are two names that come up often.

Since both treatments improve the skin by stimulating collagen, they may seem similar, but in fact, they differ from the type of energy used to the depth of action.

If you get the treatment without understanding these differences, you may end up choosing one that does not match your concerns.

Today, I’ll explain what kind of changes each treatment creates and which one may be right for your concerns.

  1. What are the effects of Eye Thermage?

Before getting into a full comparison of the effects, let’s first look at the differences between the two treatments.

What they have in common is that both improve the skin by stimulating collagen.

That is why they are often grouped together as similar treatments.

The difference lies in the energy and the depth of action.

Eye Thermage uses radiofrequency (RF) to evenly distribute heat throughout the entire dermis,

while Eye Ulthera uses ultrasound (HIFU) to concentrate energy at specific points and penetrate deeper structures.

That is why the areas they target and the results they create differ.

So let’s take a closer look at what kind of changes these differences produce.

Eye Thermage generates heat as the radiofrequency energy reaches the dermis.

This heat causes collagen to contract immediately, and over time, new collagen is formed.

Let’s look at a clinical study that shows how these changes appear in practice.

This paper objectively measured post-treatment changes using tissue biopsy with a monopolar radiofrequency device.

In the photo below, fine lines and sagging texture that had been present on the left were shown to be smoother and more refined on the right.

The researchers reported that this change was not simply due to contraction, but was the result of increased collagen I and III in the dermis, as well as increased epidermal thickness.

In other words, Eye Thermage works by rebuilding collagen itself in the dermis, and can be especially effective for fine lines, skin texture, and reduced surface elasticity.

  1. What are the effects of Eye Ulthera?

On the other hand, Eye Ulthera uses ultrasound to focus energy at a specific depth.

The 1.5 mm tip targets the dermis, and the 3.0 mm tip stimulates the orbicularis oculi muscle and orbital septum beneath it.

The key difference from Eye Thermage is that it acts on these two depths at the same time.

There is also a clinical study on how this action leads to results, so let’s take a look.

The photo below shows a comparison 12 months after the procedure.

The eye area that had been heavily sagging on the left was more lightly refined on the right.

The researchers reported that with just one treatment, the eyebrows were lifted by an average of 1 to 2 mm, and that this effect was maintained for 6 months to 1.5 years.

What stands out here is that as the deeper orbital septum tightened again, the entire sagging area was lifted.

In other words, Eye Ulthera can be seen as a treatment that addresses sagging itself by acting on the deep structures that cause it.

  1. Eye Thermage, Eye Ulthera Which one is right for my concern?

"Then isn’t it always better to get both treatments?"

Since the roles of the two treatments are different, you might think that way.

Rather than automatically getting both, it is better to first identify what your eye-area concern actually is.

If surface elasticity has decreased and fine lines have formed in a fine, crowded pattern, or if rough skin texture is your main concern,

Eye Thermage is suitable.

On the other hand, if the area under the eyes sags heavily and drops down to the point that the eyebrows also descend, making your expression look heavy, or if sagging caused by weakened deep structures is your main concern,

Eye Ulthera is suitable.

And if both are concerns, a combination of Eye Ulthera to address sagging in the deep structures and Eye Thermage to refine the surface texture is effective.

There is no single answer to the question of which is the better treatment between Eye Thermage and Eye Ulthera.

That is because the answer changes depending on whether your eye-area concern is a surface issue or a deep-structure issue.

Also, both treatments work through a process that takes time for collagen to form.

Since changes appear over 2 to 3 months rather than immediately after the procedure, using sunscreen and maintaining moisture during this period helps the results settle in.

If you are considering a treatment, please start by looking at what your eye-area concern actually is.
