The pain pattern of lifting procedures differs depending on the type of energy and depth of action. Ultrasound-based treatments like Ultherapy PRIME® typically cause a sharp, prickling sensation or momentary stinging when energy reaches the deeper layers, while radiofrequency-based treatments like Thermage® FLX and 10THERMA mainly produce a hot, burning sensation on the skin surface.
| Category | Representative Device | Primary Sensation |
|---|---|---|
| Ultrasound (HIFU) | Ultherapy PRIME® | Sharp, prickling sensation in deeper layers |
| Radiofrequency (RF) | Thermage® FLX, 10THERMA, Alltite | Burning, hot sensation |
| Laser | Soprano Titanium | Warm heating sensation, occasional hot feeling |
Even within the same ultrasound or radiofrequency category, the perceived sensation can vary depending on the device's cooling and vibration assistance technology. For example, Alltite operates with a real-time cooling system and is applied by rubbing the device on the skin, so it is relatively less painful and feels more like a warm heating sensation. Devices like Soprano Titanium, which deliver multiple wavelengths in a warming manner, also tend to feel primarily like a heating sensation, though when energy is applied more intensely to induce slimming in certain areas, a momentary hot feeling may occur.
