Shrink vs. Ultherapy vs. Onda: Differences in Lifting Treatments and How to Choose by Treatment Area (MI.K CLINIC)

If your skin no longer feels as firm as it used to and you feel that your facial contours have lost definition, you may start considering a lifting treatment. However, even though these treatments are grouped under the name “lifting,” each device differs in terms of treatment depth, mechanism, and suitable treatment areas. Rather than searching for and choosing the most well-known treatment name without further consideration, it is important to understand the differences first. If you have been searching because you are concerned about possible side effects of Shrink, you may also wish to refer to the recovery-care information for each device below.

Key Summary

✔ Ultherapy uses high-intensity focused ultrasound to reach the fascia layer and promote collagen production in the face (forehead) and neck

✔ Shrink creates thermal coagulation points in the dermis and is used on the face (excluding the forehead), neck, and double-chin area (with a dedicated tip)

✔ Onda uses microwaves to vibrate water molecules, aiming for both tightening and fat reduction in body and facial treatments (excluding the forehead and neck)

Ultherapy: High-Intensity Ultrasound Reaching the Fascia Layer

Ultherapy uses high-intensity focused ultrasound (HIFU) to deliver energy to the fascia layer. This process is intended to promote collagen production and produce a lifting effect, and the treatment areas are the face (including the forehead) and neck. During treatment, stinging, pricking, or a sensation of coldness in the bones may occur, so anesthesia is used. Treatment intervals are generally around 3–6 months, although this may vary from person to person.

Shrink: Tightening with Thermal Coagulation Points in the Dermis

Shrink uses high-intensity ultrasound directed at the dermis to create thermal coagulation points, with the aim of tightening, lifting, and improving facial contours. Treatment areas include the face (excluding the forehead), neck, and double-chin area using a dedicated double-chin tip. A throbbing sensation may occur during treatment, so numbing cream is used. A course of at least three treatments at 3–4-week intervals is generally recommended. The perceived effects and duration of maintenance may vary from person to person.

Onda: Tightening and Fat Reduction Using Microwaves

Onda uses microwaves (10–100 GHz) to vibrate water molecules and generate heat, together with DLTD cooling. In addition to tightening and lifting, it is intended to reduce fat and improve the appearance of cellulite. Treatment areas include the face (excluding the forehead and neck) and body. It is generally described as causing little pain and is performed without anesthesia after applying oil. A course of three treatments at 3–4-week intervals is the standard approach.

How Does Recovery Care Differ by Device, Including Possible Shrink Side Effects?

For all three treatments, avoid saunas, heated spas, strenuous exercise, alcohol, and smoking for one week after treatment, and using sunscreen is essential. However, the type of anesthesia, level of discomfort, and reactions that may occur immediately after treatment differ slightly by device. Knowing this in advance can help you respond without unnecessary concern.

Possible Shrink Side Effects and Recovery Care

· Redness, swelling, and throbbing may occur immediately after treatment, but these reactions generally subside naturally

· Washing your face and applying makeup are possible immediately after treatment, but use a mild cleanser and avoid rubbing the skin vigorously. Exfoliation should be avoided because it may cause irritation

· Washing your face with lukewarm water for one week can help maintain warmth

· For two weeks after treatment, avoid cosmetic devices that stimulate the face, such as peeling, scrubbing, or meridian massage

· If you have received filler treatment, it is generally recommended to wait at least 1–2 months before undergoing Shrink

· It is advisable to apply more sunscreen, moisturizer, and restorative cream than usual

· The collagen-contraction effect gradually appears for up to four weeks after treatment, although the timing of when it is felt may vary from person to person

Possible Ultherapy Side Effects and Recovery Care

· Redness, edema, swelling, or pain may occur and are generally described as resolving within 1–2 weeks

· Because the treatment uses heat, applying a cold compress immediately afterward may reduce the effect. Washing with lukewarm water is recommended instead of using a cold compress

· Avoid strong stimulation, such as gua sha, acupressure, peeling, or scrubbing, for two weeks

· For one week, avoid saunas, heated spas, strenuous exercise that causes a sensation of heat, and swimming pools

· Washing your face and applying makeup are possible on the same day, but do so gently

Possible Onda Side Effects and Recovery Care

· Flushing may last 2–3 days, while a sensation of heat or pain may last around 3–4 days

· Breakouts caused by the oil used during treatment may appear for several days

· Simple face washing and makeup application are possible, but avoid exfoliation

· It is advisable to avoid using cosmetics and personal beauty devices for about one week

· For one week, maintain warmth by washing your face with lukewarm water, and avoid alcohol, smoking, saunas, heated spas, strenuous exercise, and swimming pools

· If you experience unusual reactions, such as itching or pain, contact the clinic

As described above, reactions such as redness, swelling, and pain may occur with all three treatments as part of the natural recovery process. However, the degree and duration may vary from person to person. During your consultation before treatment, it is advisable to explain your skin condition and lifestyle patterns in advance and receive guidance on aftercare.

The lifting method that is right for you may vary depending on your facial treatment area and skin condition. Consult with MI.K CLINIC to determine the treatment suited to your desired area and goals.
