If you have looked into skin firmness treatments, you have probably heard the names Oligio, Ultherapy, and Rejuran Healer at least once. Many people are unsure whether they should receive them separately or whether they can be done together. Today, we will summarize which layers each of the three treatments targets and why they can complement one another when performed together.
Key Takeaways
✔ Oligio uses radiofrequency for tightening, Ultherapy uses HIFU to target the fascia layer, and Rejuran Healer uses salmon-derived PN to help with hydration and regeneration, so they work on different layers.
✔ Oligio is recommended for those seeking to help prevent signs of aging, improve firmness naturally, and achieve tightening without hollowing the cheeks. It is also mentioned that combining it with Ultherapy, Rejuran Healer, or fillers can enhance the overall effect.
✔ The time at which results appear and how long they last may vary from person to person, so it is best to establish a plan suited to your condition through consultation.

Oligio: The Beginning of Natural Tightening

Oligio is a treatment that uses radiofrequency (RF) energy to deliver heat to the deeper layers of the skin, helping with firmness, lifting, and regeneration. It is usually performed using 300 shots as a standard. The procedure generally follows this sequence: self-cleansing → anesthesia (15–20 minutes when 300 shots or more are used) → the treatment itself → finishing with regenerative cream and sunscreen. During the procedure, you may feel a comfortably warm sensation. When 300 shots or more are performed, anesthesia is also used to reduce discomfort. Results are said to appear between one and three months after treatment, and it is recommended for those seeking to help prevent signs of aging, improve firmness naturally, and achieve tightening without hollowing the cheeks. Immediately after treatment, it is better to wait for the warmth to subside naturally rather than washing with cold water or applying an ice pack. Avoiding meridian or gua sha massage for at least about two weeks is also recommended. However, please note that this period and the recovery process may vary from person to person.
Ultherapy: HIFU That Reaches the Fascia Layer

Ultherapy is a treatment that delivers energy to the fascial layer of the skin using HIFU (high-intensity focused ultrasound). The tips used are also divided according to the treatment area. A 1.5 mm tip is used for areas with concerns about fine lines, such as around the mouth or on the philtrum; a 3.0 mm tip is used for areas requiring firmness, such as the cheeks or jawline; and a 4.5 mm tip is used for areas requiring more defined lifting, such as the jawline, facial contour, or double chin. A separate eye-specific tip is used around the eyes. During the procedure, you may feel stinging, prickling, or a sensation of cold reaching the bone, so it is common to receive anesthesia as well. The duration of maintenance is generally described as approximately three to six months, although this may also vary from person to person. While Oligio targets relatively superficial layers, Ultherapy targets the deeper fascia layer, meaning the two treatments can be viewed as serving different roles.
Rejuran Healer: Adding Hydration and Regeneration

Rejuran Healer is introduced as a treatment that uses PN ingredients extracted from salmon to help regulate oil and moisture balance, improve dehydration, support skin regeneration, and strengthen the skin barrier. In addition to the standard formulation used for the entire face, there is also a separate formulation designed for thin and sensitive areas such as the eye area, allowing it to be selected according to the characteristics of each area. If tightening treatments are closer to structural changes, this treatment is more focused on managing the condition of the skin itself. Perhaps for this reason, MI.K CLINIC has a separate combination treatment performed together with Ultherapy, and it is often said that the skin feels smoother in texture when it is performed alongside a firmness treatment. Please also note that the time at which results appear and how long they last may vary from person to person.
Why Receive Them Together?

The three treatments use different methods—radiofrequency, HIFU, and PN injections—and each works on a different layer. In other words, one treatment can complement areas that are difficult to address with a single treatment alone. It is also explained that adding fillers, which provide volume, can enhance the overall effect because the purposes of each treatment do not overlap and they complement one another.
