For skin firming procedures, how long the effect lasts and what it does depend on the working principle and the depth targeted. Ultrasound (HIFU) types reach the SMAS fascia layer and are suited to deeper sagging, while radiofrequency (RF) types are used for collagen regeneration in the dermis and area-specific tightening. Which procedure is suitable depends on your current skin condition and where the sagging is, rather than on your age, so it is recommended to decide after a diagnosis.
Classification by Principle: Ultrasound vs. Radiofrequency
Lifting procedures fall into two broad families: high-intensity focused ultrasound (HIFU) and radiofrequency (RF). The two differ in target depth and mechanism, so even among procedures called "lifting," the choice should match your goal.
| Type | Principle | Main target depth | Main effect | Typical duration |
|---|---|---|---|---|
| Ulthera lifting | HIFU (focused ultrasound) | SMAS layer 4.5mm / dermis 3.0mm / superficial layer 1.5mm | Deeper sagging, jawline, cheek and cheekbone contour | Clinically reported at around 1–1.5 years |
| InMode lifting | Bipolar RF + vacuum | Delivered down to the SMAS layer | Tightening of the double chin, jawline and cheeks; fat reduction and collagen production | Regular maintenance type, with effects building up over sessions |
| ONDA lifting | Ultra-short-wave Cool Wave™ | Dermis and subcutaneous fat layer at the same time | Fat reduction and collagen regeneration, with minimal damage to the epidermis | Varies by person; explained after consultation |
| Thermage FLX | Monopolar RF | Entire dermis, 2.0–3.0mm | Overall skin firming, softening of fine lines | Generally reported at 1–2 years |
| Body InMode | RF (body-specific) | Skin elasticity layer and fat layer | Fat breakdown and tightening of the abdomen, thighs and upper arms | Maintenance type, with effects building up over sessions |
※ Duration may differ depending on each person's skin condition, lifestyle and treatment area.
Features of Each Procedure and How to Choose
Ulthera Lifting — Focused on Deeper Sagging
Ulthera focuses energy on the SMAS layer while checking the treatment depth with DeepSee™ real-time imaging. It is commonly used by people in their late 30s to 50s whose main concern is sagging of the jawline, cheeks and cheekbone area.
InMode Lifting — Area Tightening and Regular Maintenance
InMode is an FDA-approved device that combines bipolar RF with vacuum and is specialized for tightening the double chin, jawline and cheek areas. While Thermage FLX focuses on overall skin firming, InMode is often used to refine the contour of specific areas.
ONDA Lifting — Minimal Damage to the Epidermis
ONDA uses Cool Wave™ ultra-short-wave technology to stimulate the dermis and subcutaneous fat layer at the same time while protecting the epidermis.
Body InMode — Firming Care Beyond the Face
Body InMode uses RF energy to stimulate the fat layer of the abdomen, thighs and upper arms and tightens the skin at the same time.
When to Start and Precautions
Sagging of the SMAS layer is generally known to progress from the mid-to-late 30s, so some people consider preventive lifting from around that time. However, even in your 20s, if sagging comes early because of your bone structure, or even in your 40s, if your skin elasticity is good, managing skin tone and texture may come before lifting. Rather than deciding on a procedure by age alone, it is recommended to use your skin diagnosis result as the basis.
- Avoiding alcohol and excessive exercise for one week before the procedure is generally recommended.
- If you are taking photosensitizing medication, you need to tell your doctor in advance.
- If you are pregnant or breastfeeding, or have a pacemaker, a consultation on whether the procedure is suitable should come first.
- Temporary redness, swelling and stinging are reported right after the procedure, and they usually settle on their own within a few hours to a few days.
- Avoiding saunas, hot packs and strenuous exercise on the day of the procedure is recommended.
- The effect is generally reported to appear gradually over 4 to 12 weeks.
