This is a guide to Ultherapy PRIME compiled by Dr. Choi Byeong-geun of SHINE U Clinic Konkuk (3 minutes walk from Konkuk Univ. Station Exit 1).
When researching lifting devices, you will often encounter the words "ultrasound" and "radiofrequency." Both aim to promote collagen production, but they act on different skin layers and produce different results. In this article, we will compare Ultherapy, a representative ultrasound device, with Tenssarma, a radiofrequency device, and examine why they complement each other when used together.
Why Collagen is Key
Collagen is a structural protein located in the dermis. As we age, collagen decreases, leading to reduced elasticity and thinning of the skin, which makes it prone to wrinkles.
Therefore, it is reported that the key to anti-aging care lies in reactivating collagen in the deeper layers.
Ultrasound vs. Radiofrequency
| Category | Ultherapy (Ultrasound) | Tenssarma (Radiofrequency) |
|---|---|---|
| Energy | High-intensity focused ultrasound | Radiofrequency |
| Target Layer | SMAS layer | Dermis |
| Main Role | Lifts sagging tissue | Improves skin texture and elasticity |
Consult to find out which is right for your skin
Ultherapy Targets Deep Layers
Ultherapy PRIME delivers ultrasound energy to the SMAS layer, creating thermal coagulation points while minimizing surface damage. This promotes collagen production and tissue contraction, which can help lift sagging facial contours, and is also reported to act on unnecessary fat cells. This device is approved by the U.S. FDA and Korea's Ministry of Food and Drug Safety.
Tenssarma Targets Superficial Layers
Tenssarma delivers radiofrequency energy to the dermis to promote collagen production. As collagen is replenished, the thinned skin regains its original thickness and becomes firmer and smoother. This device was developed in Korea and is performed by adjusting the intensity according to the skin condition.
What is Improved When Used Together?
Since the two devices act on different layers, using them together can address both deep sagging and superficial skin texture.
- Ultherapy lifts sagging tissue.
- Tenssarma refines pores, fine lines, and texture.
- Together, they work to increase collagen density.
However, the proportion of the two devices may vary depending on which concern is more prominent, so the combination is determined based on a diagnosis.
Conclusion
Ultrasound and radiofrequency are not competing technologies but rather tools that act on different layers. The appropriate combination varies depending on your skin condition, so a diagnosis comes first.
