Thermage vs. Domestic RF,

The 1.3 mm depth difference that determines the result

"I got domestic treatment,

but I couldn’t really tell the difference,"

is something I hear from many people.

Today, I’ll walk you through why that is, step by step.

Domestic RF and Thermage,

They all look similar, right? But here’s the thing

Thermage FLX uses radiofrequency (RF)

to deliver heat deep into the dermis,

making it a lifting device.

Domestic devices use the same basic method, but

output stability and penetration depth are different.

It’s actually hard to simply say, "Same principle means same effect."

If you get domestic RF often, does it become like Thermage?

Actually, it’s the exact opposite

Key point of this article

Domestic RF reaches a depth of 3 mm,

while Thermage FLX reaches up to 4.3 mm.

This 1.3 mm difference

determines whether it reaches the SMAS layer.

"If I get domestic treatments several times,

won’t it become similar to Thermage?"

I get this question a lot.

But there are areas that can be compensated for with repeated sessions,

and areas that simply can’t be.

The key is 'depth.'

Domestic RF usually delivers heat to about

3 mm deep in the dermis.

By contrast, Thermage FLX

reaches as deep as 4.3 mm.

That’s only a 1.3 mm difference on paper, but

the SMAS layer (fascia) lies within that range.

The SMAS is a net-like structure

that suspends the face,

and lifting occurs when heat reaches it.

If it only reaches 3 mm,

dermal collagen stimulation is still enough, so

skin texture improves.

But the force that lifts sagging itself upward

will inevitably be limited.

Director Wi Young-jin’s key summary

The difference is not the brand, but

the 'reached depth.'

If you only want dermal elasticity, domestic devices are enough.

But if you want to lift sagging lines upward,

it needs to reach the SMAS layer.

So, is Thermage right for me too?

If you don’t really have sagging,

and only have rough skin texture, Thermage may

feel less cost-effective.

However, for those whose sagging has already started,

it is still the most proven option.

Also, before the procedure, checking the genuine tip is

not optional—it’s essential.

Ask them to show you the tip box directly, and

the genuine-product certification sticker

is safest if you remove it yourself.

If you’ve read this far,

you’re probably wondering this

Q1. Can I get domestic RF and Thermage together?

A. Getting them together is fine.

But make Thermage your main treatment once a year.

In between,

adding domestic treatments as a support

creates the best synergy.

Q2. If one Thermage session costs the same as four domestic sessions,

isn’t that better?

A. If your goal is elasticity maintenance,

multiple domestic sessions make sense.

But if your goal is to lift sagging lines,

even ten domestic sessions

can’t match one Thermage treatment.

Q3. Does Thermage make your face lose fat?

A. If someone with a thin face gets high-output treatment,

their cheeks may look sunken.

That’s why it’s important to carefully evaluate your facial shape and fat volume

before the procedure.

If you take away just one thing from today,

—the difference between Thermage and domestic devices is

whether or not it reaches the SMAS layer.

In the next article,

I’ll explain the 'specific steps for checking the genuine tip'

with photos.

Frequently asked questions

Q. Can I get a Korean RF treatment and Thermage together?

A. Getting them together is fine. However, make Thermage your main treatment once a year.

Q. If the cost of one Thermage treatment gets you four domestic treatments, isn’t that better?

A. If your goal is to improve skin elasticity, several sessions with domestic treatments are a reasonable option.

Q. Will Thermage make my face look thinner?

A. If you have a thin face, receiving treatment at high intensity may make your cheeks appear sunken.

Q. I'm in my early 30s and looking for preventive care. Should I get Thermage, or would a Korean RF treatment be sufficient?

A. If you are in your early 30s with minimal sagging and looking for preventive care, a Korean-made RF device is a great fit, and Thermage might be a bit premature. Thermage FLX reaches 4.3mm down to the SMAS layer to lift sagging contours, making it much more beneficial for those who have already started to notice sagging.
