When do XERF results show, and how many sessions?
"When will I see it?" and "How many sessions?" come as a pair. Here is what research says and what it does not.
The short answer
Results arrive in stages: immediate tightness mixes contraction with swelling; in one study pores changed at one month and wrinkles at three. We judge at about 3 months. Studies used only one or two sessions and none compared intervals. Miso Clinic in Daegu performs XERF often and decides the next step at 3 months.
What shows when?
| Time | Finding | Caveat |
|---|---|---|
| Immediately | Tightness, volume shift | Mixed with swelling |
| 1 month | Pore scores changed (16 people) | Wrinkles not yet |
| 90 days / 3 months | 92.3% rated improved (39) / wrinkle scores changed (16) | No control group |
| 12 weeks | Blinded raters picked after photo 80% (20) | One session |
How many, how often?
XERF studies used one or two sessions and none compared intervals, so "every six months" is not from research. After results settle at 3 months, we decide with matched photos.

How we judge
Photos taken with the same light, angle and expression as before are compared side by side at about 3 months, more reliable than a mirror. Miso Clinic in Daegu performs XERF often and keeps all four effectors (i05, i10, E40, E60).

How does the consultation work, and how do I book?
On a first visit we take photos from the front, at 45 degrees and from the side, and together we pick the one concern that bothers you most. I'll ask about any medications you take, any metal or electronic implants in your face, and whether you might be pregnant, and then I split things into what we can do today and what can wait for later. It's completely fine to come in just for a consultation and go home.
