Thermage Candidates and Contraindications

Thermage is suited to adults with mild-to-moderate dermal laxity, including body-area laxity (abdomen, inner arms, knees, thighs) where lifting devices are less effective. It is contraindicated in patients with cardiac pacemakers or implantable cardioverter defibrillators (ICDs), permanent metal implants in the treatment area, pregnancy, active infection in the field, and after recent fillers or threads (waiting period applies). Patients with severe laxity should consider surgical lifting or Ultherapy.

Thermage is broadly tolerated and is appropriate for most adults with mild to moderate skin laxity, but the device has specific contraindications that follow from its mechanism — monopolar radiofrequency delivers electrical energy through tissue, which is not compatible with certain implants. Candidacy is decided in consultation, but the points below are the ones that come up consistently.

Good candidates

The patient most likely to be satisfied with a single Thermage session has mild or moderate dermal laxity rather than severe descent of deeper tissue — the kind of change that comes with the first decade or so of visible skin ageing. Age is not the criterion; laxity profile is. A patient in their thirties whose skin firmness has started to soften is a candidate; so is a patient in their sixties whose laxity is dermal rather than at the SMAS level.

Body-area patients are a distinct candidate group. Thermage body tips are used on the abdomen (post-pregnancy or post-weight-loss laxity), inner arms, knees and inner thighs. Patients who have ruled out body-contouring surgery and who want a non-invasive option are typical candidates here. Body Thermage does not produce surgical results, but it produces a measurable improvement in firmness when the underlying laxity is mild to moderate.

Patients who have previously had Ultherapy and want additional dermal-level firmness — particularly across cheeks and upper neck — are candidates for Thermage as a complement. The two devices target different depths and do not interfere with each other.

Less suitable candidates

A patient with severe laxity — heavy jowls, deep neck banding, substantial mid-face descent — will not be satisfied with Thermage alone. The amount of tissue movement they want is in surgical territory rather than non-invasive. A discussion of the realistic result range, and of whether Ultherapy might be more appropriate as the non-surgical option, is part of the consultation rather than a push to book the device the patient asked about.

Patients who have had recent filler or thread procedures in the treatment area benefit from a waiting period before Thermage. Heat applied over a hyaluronic acid filler can accelerate breakdown of the filler product, and energy delivered over absorbable threads can interfere with the thread response. Timing varies by the specific filler or thread used; this is decided case-by-case.

Contraindications

The contraindications below are categorical rather than case-by-case. The first three matter specifically because Thermage delivers monopolar radiofrequency. The published safety record on eyelid and periorbital treatment (Biesman et al., 2006) and on body-area RF (Anolik et al., 2009) is good when contraindications are respected and the protocol is delivered as designed.

• Pacemaker or implantable cardioverter defibrillator (ICD). Monopolar RF current can interfere with implanted cardiac devices. Thermage is not used in patients with these implants.
• Metal implants in the treatment area. Permanent metal implants in the field of treatment can concentrate RF current. Dental implants are not normally in the treatment field for face Thermage; orthopaedic implants in body areas to be treated are a contraindication for that area.
• Pregnancy. Thermage is not performed during pregnancy. There is no safety dataset for the procedure in pregnant patients and there is no clinical indication that would require it.
• Active infection or inflammation in the treatment area. Treatment is deferred until the area is settled.
• Recent fillers or threads in the treatment area. Waiting periods apply; this is a timing consideration rather than a permanent exclusion.
• Severe systemic illness or uncontrolled connective tissue disorder. Treatment decisions are made in consultation with the patient's primary care or speciality team.

What the consultation actually covers

For an international patient, the consultation begins with a photograph review over WhatsApp, Line or KakaoTalk; the in-person meeting on the treatment day confirms the plan. The clinician assesses laxity, identifies the tip type (face, eye, body) most appropriate to the area, and estimates the total pulse count, which in turn drives the price. If Thermage is the wrong device for the patient's actual concern, that is said directly rather than worked around. The consultation also covers contraindications by history — pacemaker and ICD status, implanted metal in the treatment area, pregnancy status, and recent filler or thread history.
