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).
Among non-surgical lifting procedures, Ultherapy is often mentioned as a device with a long history. Ultherapy PRIME is not a single new product, but rather refers to a sophisticated protocol that combines Ultherapy device technology and treatment know-how, tailored to each individual. Let's summarize what has evolved from an academic perspective.
Imaging Technology for Viewing and Treating Inside the Skin
The biggest feature of Ultherapy is that the practitioner can directly view the inside of the skin and deliver ultrasound energy. Through real-time ultrasound imaging, the practitioner can confirm the thickness and location of the SMAS layer and dermis, which are the core targets for lifting, as well as surrounding nerves and blood vessels, while delivering energy. This imaging technology is related to the accuracy and safety of the procedure.
When high-intensity ultrasound is focused on a single point to create a thermal coagulation point of 60-70 degrees, tissue contraction immediately after the procedure induces tightening, and in the long term, fibroblasts are activated, promoting collagen and elastin production.
Role of Transducers by Depth
Ultherapy uses tips of different depths to treat various layers of the skin.
| Tip | Target Depth | Main Role |
|---|---|---|
| 4.5mm | SMAS layer | Lifts the fundamental cause of sagging |
| 3.0mm | Deep dermis, fat boundary | Collagen regeneration, density reinforcement |
| 1.5mm | Shallow dermis | Improves fine wrinkles around the eyes and mouth, and skin texture |
What the PRIME Protocol Adds
Ultherapy PRIME applies the following to enhance treatment efficiency and satisfaction, based on the strengths of the device:
- Precise facial analysis. Identifying skin thickness, fat volume, and direction of sagging with imaging.
- Strategic shot distribution. Concentrating 4.5mm on severely sagging jawlines and double chins, distributing 3.0mm to cheeks and nasolabial folds, and 1.5mm to the thin eye area.
- SMAS layer and fat layer control. Avoiding or reducing energy in areas that should not be hollowed to prevent side effects.
"Isn't it enough to just get a lot of shots evenly?" This is a frequently asked question. Distributing shots according to the direction of sagging and fat distribution, rather than uniform shots, is more related to natural results. However, individual results may vary.
If you are curious about the shot distribution suitable for your facial structure, you can find out during a consultation with Dr. Choi Byeong-geun. Please leave a chat consultation.
Addressing Both Surface and Deep Layers with Combination Treatments
While Ultherapy plays a role in lifting the deep SMAS layer, high-frequency devices like Thermage FLX play a role in filling the overall density and elasticity of the entire dermis. This method enhances completeness by treating the surface and deep layers separately.
The appropriate combination for you will be determined after a diagnosis. If you have any questions, please feel free to inquire via chat consultation.
