Xtherma is a monopolar radiofrequency treatment that pairs deep-heating RF energy with simultaneous cryogen cooling in the same pulse, allowing effective energy delivery while protecting the skin’s surface. The result is stimulated collagen remodeling for firmer, tighter skin — with no incisions, no needles, and no downtime.
How it works
Xtherma delivers monopolar radiofrequency energy at 6.78 MHz to heat the deep dermis, triggering immediate collagen contraction and longer-term collagen remodeling. A cryogen cooling system fires in the same pulse as the RF energy, protecting the epidermis and allowing higher, more effective treatment temperatures to be used comfortably and safely.
What it treats
- Facial laxity and jowls
- Neck and décolletage tightening
- Arms, abdomen, and other body areas with mild-to-moderate laxity
What does the research show?
Xtherma is one of several monopolar radiofrequency platforms built around a well-established treatment mechanism. Published histologic research on monopolar RF — including a 2020 study in the Journal of Cosmetic Dermatology — has documented measurable, biopsy-confirmed increases in dermal collagen density following a single treatment session, with continued improvement over 6 months. This class of technology has an established evidence base for stimulating the skin’s own collagen-remodeling process, though results vary by treatment area, skin type, and degree of laxity.
What to expect
A typical Xtherma session takes 30–45 minutes depending on treatment area, with a warming sensation offset by the device’s simultaneous cooling. Most patients experience only mild, temporary redness that resolves within a day or two, allowing an immediate return to normal activities. Some patients notice initial firming right after treatment from immediate collagen contraction, with the most significant improvements appearing gradually over 2–3 months as new collagen forms.
Is Xtherma right for you?
Xtherma is well suited for patients with mild-to-moderate skin laxity who want a non-surgical option — whether that’s early jowling and facial laxity, loose skin on the arms or abdomen, or general skin firming without surgery or downtime. During your consultation, our team will assess your skin and goals to determine whether Xtherma on its own, or in combination with other HALO treatments like Density or Ultherapy Prime, is the best fit.
Frequently asked questions
Is Xtherma painful? Most patients feel a warming sensation balanced by the device’s simultaneous cooling; discomfort is generally mild.
How many sessions do I need? Many patients see improvement from a single session, though your provider may recommend a series depending on the degree of laxity being treated.
Is there downtime? No significant downtime is expected; mild, temporary redness is the most commonly reported side effect and typically resolves within a day or two.
