Visiting Seoul for a short stay
Thermage FLX is done in one visit. You can wash and wear makeup right after; use lukewarm water for 3 days and skip heavy drinking, saunas, hot baths and hard exercise for about 7 days.
Thermage FLX mechanism
Thermage FLX sends monopolar radiofrequency energy through the skin surface to heat the dermis. The heat makes existing collagen contract and starts new collagen production, which is why skin elasticity improves gradually over the following months.

U.S. FDA-cleared indication
The manufacturer lists non-invasive treatment of wrinkles around the eyes, including the upper and lower eyelids, among its cleared uses. At Beauty Z the treatment area is agreed with your doctor at consultation.
