FAQ

Frequently Asked Questions

How long does the treatment take?
XERF requires no separate anesthesia, so treatment can begin right away — typically 15 to 30 minutes depending on the number of shots.
Can I return to daily life right away?
Because energy is delivered into the skin, you can generally return to daily life immediately, with no separate recovery period.
Is anesthesia required?
The ICD Cooling system effectively lowers surface temperature to reduce discomfort, and the variable pulse is designed for stable treatment.
Is it safe?
XERF is a medical device approved by the Korean MFDS with verified safety.
Which EFFECTOR, and how many shots?
The right tip, shot count and interval differ by skin condition and area. Confirm your plan in a 1:1 consultation with Dr. Kim.
What aftercare is needed?
As a non-invasive device, no special aftercare is required. Makeup is fine the same day.
XERF is a medical device approved by the Korean Ministry of Food and Drug Safety. Results and recovery vary by individual; please consult a medical professional before treatment.
