XERF in Korea: how is it different from Thermage, and should you try it?
XERF is a newer Korean radiofrequency device that heats the skin at more than one depth, used for tightening and texture much like Thermage. It suits early laxity and people who want an RF option at a different price point. Seoul price: $250–$1,215.

START WITH THE CONCERN
Which one is for what you actually want?
Most people arrive with a product name from social media. The doctors we work with start from the concern instead, and sometimes the answer is a different treatment, or none.

HONESTLY
When we would tell you not to book it
- You want long-term published data. XERF is newer than Thermage, so there is less independent evidence; ask what the clinic has seen.
- The quote has no shot count.
- You have a pacemaker or implanted electronic device.
- You are pregnant.
HOW WE CHOOSE YOUR CLINIC
We vet the clinics first.
Then we match you to the doctor.
Seoul has hundreds of clinics selling XERF. We work with a short list that meets five conditions, and introduce you to the one or two doctors who fit your concern, your dates and your budget.
- 01
The consulting doctor is the treating doctor
We ask every clinic who actually holds the needle. A clinic that hands you to someone else after the consultation does not make our list.
- 02
Product, device and dose are named
“Premium booster” is not an answer. We only work with clinics that tell you the brand, the volume and the machine before you sit in the chair.
- 03
A written quote, per unit or per cc
So you can compare two clinics on the same scope rather than two totals that measure different things.
- 04
A doctor willing to say “not this”
We listen for it in consultations we sit in on. A clinic that agrees to everything is selling, not advising.
- 05
Someone to contact after you fly home
A named contact and channel for follow-up questions, agreed before treatment rather than discovered after.

QUESTIONS PEOPLE ACTUALLY ASK
XERF: the short answers
How much is XERF in Korea?
In Seoul, about $250 for 100 shots, about $630 for 300 shots, and about $1,135–$1,215 for 600 shots.
XERF vs Thermage: which is better?
Both are RF tightening devices. Thermage has a longer track record; XERF is newer and often priced lower. Neither is universally better; ask your doctor which suits your skin thickness and goals.
Does XERF hurt?
You feel heat. Numbing and cooling are used; tolerance varies between people.
Can I combine XERF with Ultherapy?
Many clinics combine RF and HIFU because they work at different depths. Your doctor decides the order and whether it is the same day.
