Work backwards from departure
Put your departure date at the end of the plan, then leave the recovery time the doctor describes for your case, then a spare day in case your skin reacts more than expected. The treatment day goes before that.
Booking the consultation early in your stay leaves room to think, to compare a second clinic, or to come back for a check before you leave.
What "downtime" covers
Downtime is the period when skin may look red, swollen, crusted or bruised, or when you are asked to avoid sun, heat, exercise, alcohol or makeup. It differs by treatment, settings and person.
Ask for recovery instructions for the procedure, settings and combination proposed for you. Record when travel and usual activities can resume; this page does not supply a universal waiting period.
Things to keep clear after treatment
Sightseeing in strong sun, saunas and jjimjilbang, long hot baths, swimming pools and heavy exercise are common things clinics ask you to pause for a while after some treatments. Plan quieter days just after the treatment.
The flight itself
Cabin air is dry. Ask the clinic what you may apply during the flight, pack it in your hand luggage within liquid limits, and keep the aftercare sheet and the clinic's contact details with you.
