Alltite vs. Thermage® FLX: What's the difference between these two radiofrequency treatments?

Alltite avoids high-temperature zones that can burn tissue and heats gradually at a relatively lower temperature, so it tends to cause less discomfort. Pain generally increases with the peak temperature reached in a short time; Thermage® FLX delivers intense heat to the dermis in brief pulses, causing repeated sharp heat sensations deep in the skin. Alltite's target temperature is lower and the heat rises progressively, so many people experience it as a warm, soothing sensation.

This makes Alltite an accessible option for those who are sensitive to pain and find Thermage® FLX or HIFU Lifting uncomfortable. However, pain perception varies individually, and even with a lower-temperature method, the heat sensation may differ depending on the area and energy level.

Yes, both devices use radiofrequency (RF) technology, but they generate heat and manage temperature differently. Thermage® FLX uses monopolar radiofrequency to deliver intense heat to the dermis in an instant, causing immediate collagen contraction, while protecting the epidermis with cooling gas—a "strong and fast" heating approach. Alltite, on the other hand, is known to use a dielectric heating method that induces heat in water-rich tissue layers, maintaining a relatively lower temperature over a broad area for a longer time—a "gentle and sustained" heating approach.

Note that some people mistakenly think Alltite is an ultrasound (HIFU) device, but Alltite is a radiofrequency-based lifting device, not ultrasound.

Looking only at the cost per session, Alltite tends to be more affordable, but to accurately assess "value for money," you need to consider the number of sessions and the maintenance plan. Thermage® FLX has a higher per-session cost due to the expense of genuine disposable tips, but it is typically done about once a year. Alltite has a lower per-session cost but involves multiple sessions. The total cost depends on the treatment area, number of shots, session structure, and whether genuine consumables are used.

Therefore, rather than saying one is unconditionally cheaper, it is more reasonable to compare the overall management plan based on pain burden, number of visits, and desired improvement. Considering the session schedule and maintenance intervals will give you a more accurate idea of the actual cost.

Yes, although both are radiofrequency-based, their heating methods and stimulation intensity differ, so they can be used alternately with appropriate intervals. For example, you could have a strong collagen stimulation with Thermage® FLX once a year and maintain elasticity comfortably with Alltite in between. For those who find it difficult to have Thermage® FLX every year due to pain or schedule, Alltite can serve as an interim maintenance option.

However, since both treatments use thermal stimulation, the interval and energy level should be adjusted based on your skin's recovery status, and the order and frequency depend on your skin condition. Heal House has both Thermage® FLX and Alltite, so we can design a personalized annual elasticity management plan that combines the two devices after a consultation.
