Quick answer: Ultherapy uses focused ultrasound to lift from the deep SMAS layer, so it suits sagging jowls and jawlines. Oligio is a Korean radiofrequency device that heats the skin more evenly, so it suits loose, thin or crepey skin and fine lines. Many people combine them for both lifting and firmness.
Key takeaways
- Ultherapy is focused ultrasound; Oligio is monopolar radiofrequency (RF).
- Ultherapy works in points at set depths, down to the SMAS support layer.
- Oligio heats a broad area of skin to tighten it and improve texture.
- Ultherapy is better for lifting; Oligio is better for overall skin firmness.
- Oligio is often called the Korean alternative to Thermage.
What is Ultherapy?
Ultherapy is a micro-focused ultrasound treatment by Merz Aesthetics. A live ultrasound image shows the skin layers, so the doctor can place small points of heat at 1.5 mm, 3.0 mm and 4.5 mm. The deepest points reach the SMAS, the layer that holds up the face. New collagen forms over two to three months, lifting the jawline, cheeks and brows. Results usually last about a year.
What is Oligio?
Oligio is a monopolar radiofrequency device made by WONTECH, a Korean company, and approved by Korea's Ministry of Food and Drug Safety. Radiofrequency energy heats the deeper layer of the skin (the dermis) evenly across the treated area. This makes existing collagen tighten and encourages new collagen to grow. A cooling system protects the surface, and the energy is delivered in a way that many patients find more comfortable than older RF treatments.
Because RF heats a wide area rather than single points, Oligio is good at firming and smoothing the skin itself. It is popular for loose skin on the cheeks, fine lines, crepey skin around the eyes and early sagging.
Ultrasound vs radiofrequency: what is the difference?
Think of ultrasound as precise and deep, and radiofrequency as broad and even. Ultrasound focuses energy into tiny points at a chosen depth, so it can reach the SMAS without heating the skin surface much. Radiofrequency spreads heat through the skin layer, so it tightens the whole skin surface and improves texture. Each one does something the other cannot fully do, which is why they are often combined.
How do Ultherapy and Oligio compare?
- Energy: Ultherapy focused ultrasound; Oligio monopolar radiofrequency.
- Main layer: Ultherapy SMAS and skin; Oligio the dermis.
- Best for: Ultherapy for sagging and contour; Oligio for loose, crepey skin and fine lines.
- Live imaging: Ultherapy yes; Oligio no, but it has surface cooling.
- Comfort: Ultherapy can feel sharp over bone; Oligio feels like warm heat pulses.
- Results: both build gradually over two to three months.
Which is better for sagging jowls and jawline?
Ultherapy is usually the better choice for a heavy lower face, jowls or a soft jawline. Lifting the deep support layer gives a more noticeable change in face shape. People in their 40s and 50s with visible sagging often start here.
Which is better for loose or crepey skin?
Oligio is often the better choice when the main problem is the skin itself: thin, loose or crepey skin, fine lines or uneven texture. It is also a good option for people with slim faces who do not want deep energy, and for people who want firmer skin with very little downtime.
Can you combine Ultherapy and Oligio?
Yes. Combining ultrasound and radiofrequency is one of the most common lifting plans in Korea. Ultherapy lifts from deep down, and Oligio tightens and smooths the skin on top. They can be done on the same day or a few weeks apart. Your doctor will choose the order and energy after checking your face.
What is the downtime?
Both treatments have little downtime. After Oligio, skin may look pink for a few hours. After Ultherapy, mild swelling or tenderness along the jaw can last a few days, and small bruises are possible. Most visitors return to sightseeing the same day.
Is it safe?
Both are widely used and safe when performed by experienced doctors with genuine devices and tips. Rare risks include burns, blisters or temporary numbness. Tell your doctor about any metal implants, pacemakers or recent fillers, as these may affect radiofrequency treatment.
How to choose between them
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Lifting and tightening treatments are some of the most popular choices. If sagging is your main concern, start with Ultherapy. If loose or crepey skin bothers you more, Oligio may suit you better. If you have both, a combined plan often works best.
Frequently asked questions
Is Oligio the same as Thermage?
No. Both use monopolar radiofrequency, but Oligio is a different, Korean-made device. Many people find it more comfortable.
Which one hurts less?
It depends on the person, but many find Oligio milder. Numbing cream helps with both.
How long do results last?
Results build over two to three months. Ultherapy usually lasts about a year; Oligio results often last several months to a year.
Can I do both on one trip?
Yes. Many visitors have both on the same day because the downtime is short.
