Ultherapy or Thermage: what is different, and do you need both?
“Which is better, Ultherapy or Thermage?” “Do I really need both?” “Wouldn’t that overlap and waste money?”
These are the three most common questions in lifting consultations.
First, neither is simply better or worse. They address different layers. One is enough for some people, both are needed for others, and for some, it is too early for either.
I recommend just one more often than I recommend both. There is no reason to treat a layer that does not need it.

Skin is not a single layer—devices target different depths
A cross-section shows the epidermis, dermis, subcutaneous fat, and beneath them the fascial layer called SMAS. Aging changes differ by layer. Loss of dermal collagen reduces elasticity and creates fine lines. Loosening of the SMAS gives a sense of the whole face sagging downward. Different causes require different approaches.
“How deep are these layers?” people ask. The differences are measured in millimeters. The dermis is roughly 1–4mm from the surface, while the SMAS is usually deeper, depending on the area. Ultherapy addresses this with focused ultrasound, or HIFU. Like a magnifying glass focusing sunlight, it concentrates ultrasound using separate tips aimed at depths of 1.5mm, 3.0mm, and 4.5mm. The 4.5mm tip delivers thermal stimulation near the SMAS, the foundation involved in sagging. Thermage FLX uses radiofrequency. Instead of focusing energy at a point, it spreads heat relatively broadly through the dermis to induce collagen contraction and regeneration. Its emphasis is skin-surface firmness and texture. Different target layers naturally lead to different directions of change.
“Will Ultherapy alone do everything?” One treatment cannot solve every issue
I answer cautiously: sometimes it is enough, and sometimes it is not. If deep-layer sagging is the main issue, I consider Ultherapy first. If loss of dermal elasticity stands out, Thermage may take priority. Many people, however, have both changes progressing together.
Think of a building. New wallpaper cannot fix leaning pillars; straightening only the pillars while neglecting the walls leaves an unfinished result. What to address first differs by building—or face. Even among people in their forties, plans differ between those whose dermis is holding up and those whose fascia is beginning to loosen, so my recommended order varies. I also often hear, “Isn’t the more expensive one better?” The criterion is the layer, not price. A device that misses the layer where your problem lies is not your answer, however good it may be.

If combining them, how are order and intervals chosen?
For people with issues in both layers, we discuss a spaced combination plan. Some worry, “Won’t doing both burden the skin?” Different layers are targeted, so it differs from treating the same place twice. Still, doing everything at once is not automatically best. Depending on the skin, I prefer intervals of several weeks, checking the first treatment’s response before moving to the next step. Collagen regeneration generally unfolds over 2–3 months rather than immediately, so assessment must follow that pace. Not rushing is often the faster path.
How we approach it at LUNN
Many clinics around Cheongdam and Apgujeong have lifting devices. My principle is simple: diagnosis comes before device names. I personally provide consultation, treatment, and aftercare. Only after assessing skin thickness, the location and degree of sagging, and fat volume by looking and palpating do I discuss equipment. LUNN has both Ultherapy and Thermage FLX, so there is no reason to begin consultation with a predetermined conclusion. Either may cause temporary redness, swelling, or tingling. Collagen regeneration varies individually, as do the timing and degree of results. Explaining this beforehand is part of my role. Consultation and treatment take place in private rooms, allowing enough time to ask questions comfortably. We are a 1-minute walk from Exit 4 of Apgujeong Rodeo Station, making return visits to check progress convenient.

The choice between Ultherapy and Thermage depends on which layer of your skin is affected, not on a device description. A place that identifies and explains that layer is a good choice, even if it is not LUNN.
