Thermage FLX

How it works

Thermage FLX, made by Solta Medical, uses monopolar radiofrequency. Radiofrequency energy passes through the skin and meets natural resistance in the tissue, which produces heat in the deeper layers. A handpiece with a treatment tip is moved over the skin while cooling protects the surface. The purpose is to warm the dermis to a controlled temperature to stimulate a gradual tightening response.

Good to know

• The heat is delivered in repeated pulses, so the practitioner covers each zone multiple times; larger areas can lengthen the visit.
• Many people report warmth and brief hot flashes; a doctor can talk through comfort options.
• Short-term effects include flushing or mild swelling, but most people look normal soon after.
• People with pacemakers or certain electronic implants are typically advised against radiofrequency treatments.

What a Thermage FLX session means for your travel days

Block a half-day around the appointment rather than a short slot, since larger areas and cooling can extend time in the chair. The rest of the day can stay light.

Any firming effect builds slowly, so treating in the first half of the trip gives you a gentle runway, and nothing is lost if the flight home comes soon after.
