InMode vs. Thermage vs. Ultherapy: The Real Differences After 3 Months

Information as of August 2026

Radiofrequency Technology is Key

The Crossroads of Choice Seen in the Consultation Room

A woman in her mid-30s, working professionally, held different brochures in each hand and asked, "Both InMode and Thermage are lifting treatments, so why is there a double price difference? Isn't the more expensive one better?" Just by looking at her eyes, it was clear she had already read dozens of reviews online.

Searches comparing lifting procedures increased by 340% in 2023 compared to the previous year, with 'InMode Thermage difference' being the most searched term. Although they are categorized under 'radiofrequency lifting,' the depth and method of energy delivery are completely different.

To be honest, the formula 'more expensive is always better' doesn't apply here. Managing pores for someone in their 20s and addressing sagging jawlines for someone in their 40s are entirely different issues. Today, I'll break down InMode, Thermage, and Ultherapy based on their energy depth and target tissue.

Three Methods Based on Energy Depth

InMode (InMode FX/Forma) targets the epidermis and upper dermis at a depth of 1.5-3mm. It delivers heat directly to the dermis via needle electrodes (microneedle RF) or tightens the surface in a non-invasive mode. FDA approval was in 2019, and it primarily aims to improve pores, fine wrinkles, and skin texture.

Thermage (Thermage FLX) reaches 3-4.5mm, from the deep dermis to the subcutaneous fat layer. It uses a monopolar RF method to deliver high heat over a wide area, inducing collagen remodeling. Evolving through four generations since its first FDA approval in 2002, it focuses on improving sagging.

Ultherapy (Ulthera) uses ultrasound (HIFU) to penetrate up to the SMAS layer (fascia) at 1.5-4.5mm. It contracts only the fascia without affecting the skin surface, earning it the title of the deepest lifting achievable without surgery. FDA approved in 2009, its duration of results is reported to be 12-18 months.

Key Point The SMAS layer is a thin membrane that surrounds the muscles beneath the skin. It's the very layer surgeons pull when performing actual facelift surgery. This is why Ultherapy is called 'non-surgical lifting.'

Why Does the Timing of Perceived Effects Vary So Much?

With InMode, you feel an improvement in skin elasticity immediately after the procedure because heat is delivered directly to the epidermis and superficial dermis. As collagen regeneration begins in earnest after two weeks, the pore-tightening effect peaks around week four.

Thermage requires some patience. Immediately after the procedure, your face might look puffy due to swelling. The real effects appear after 2-3 months as collagen is remodeled. This is why the patient satisfaction survey in a 2022 report by the Korean Dermatological Association used '3 months later' as the assessment point.

Ultherapy falls somewhere in between. Since the fascia contracts immediately, you'll notice your jawline lifted within the day to a week, but the final results are solidified only after collagen synthesis is complete in 2-3 months. However, the pain is the most intense among the three — it's often difficult to tolerate with just numbing cream, so many opt for sedation.

• InMode: Immediate elasticity + 4-week pore peak
• Thermage: High satisfaction after 3 months of collagen remodeling
• Ultherapy: Jawline lift in 1 week + final fixation in 3 months, most painful

Cost and Duration of Results: A Realistic Calculation

InMode costs 300,000 to 800,000 KRW per session, and typically 3-4 sessions are recommended at 1-2 month intervals. The total cost ranges from 1.2 to 3.2 million KRW, and the effects last for 6-12 months. Because it targets shallower layers, collagen regenerates quickly, but the duration of results is shorter.

Thermage costs 1.5 to 3 million KRW per session, with one session per year generally recommended. The collagen remodeling is so powerful that one session lasts for 12-18 months. However, covering the entire face at once can require 900-1200 shots, leading to a significant cost burden.

Ultherapy costs 2 to 4 million KRW per session, with a duration of 12-18 months, similar to Thermage. Since it affects the fascia, once contracted, it stays that way for a long time. However, some people are reluctant to undergo repeat procedures due to the pain, so in reality, treatments are often spaced 1.5-2 years apart.

Tip Thermage and Ultherapy are often priced 'per shot.' For the entire face, 900 shots for Thermage and 300-600 lines for Ultherapy are typical ranges. Always confirm the total number of shots when getting a quote.

20s vs. 40s: Completely Different Selection Criteria

For those in their late 20s to early 30s, fascia sagging is not yet an issue. Their concerns are mainly about enlarged pores, oiliness, and skin texture. In this case, InMode is a perfect match for their needs. Its purpose is to stimulate the upper dermis to tighten pores and smooth skin texture.

For those in their mid to late 30s and 40s, the situation changes. When sagging cheeks and nasolabial folds begin to appear, the cause is collagen loss in the deep dermis. From this point on, Thermage becomes effective, as it delivers high heat over a wide area to tighten the entire dermis.

For those 40s and older with a blurred jawline, it's time to consider Ultherapy. Simply tightening the skin isn't enough; you need to lift the fascia from the underlying layer to restore the jawline. However, you must be prepared to endure the pain and the cost. If pain is a concern, Thermage is a realistic compromise.

• 20s: Pores, Skin Texture → InMode
• Mid-to-late 30s: Cheek Sagging, Elasticity → Thermage
• 40s and older: Jawline, Fascia → Ultherapy (Pain tolerance essential)

Key Takeaway: Depth Determines the Goal

The commonality among these three procedures is 'collagen regeneration.' However, the problems they address differ completely depending on the depth targeted. InMode focuses on surface refinement, Thermage on mid-layer volume, and Ultherapy on deep-layer lifting.

There's something not mentioned in advertisements: Ultherapy, being the deepest and most expensive, isn't necessarily the best for everyone. Using Ultherapy for pore concerns in your 20s is like using a cannon to hit a sparrow. You need to first understand your skin's age and the depth of your concerns.

• Energy Depth = Target Tissue = Problem to Address — Choose in this order
• Compare costs not per session, but 'per duration of results'
• Decide beforehand whether you can tolerate pain to narrow down your options
• Ultherapy for 20s' pores is overkill — Match your age and concerns first

Common Misconceptions

What to Check Before the Procedure

• Genuine device certification (Serial numbers can be verified for InMode, Thermage, and Ultherapy) — Beware of low-cost counterfeit devices.
• Ultherapy is very painful, making driving or returning to work difficult on the same day — Keep your schedule clear for the next day.
• Thermage may cause temporary puffiness for 2-3 days after the procedure — Avoid important events within a week.
• Cannot be performed if pregnant, breastfeeding, have keloid tendencies, or have facial implants (silicone, etc.).
• Avoid alcohol, saunas, and strenuous exercise on the day of the procedure — Increased blood circulation can worsen swelling and bruising.
