Ultherapy lifting, is the effect real? Is the pain tolerable?

Ultherapy, Frankly Speaking from Its Effects and Pain

Ultherapy is a non-surgical lifting treatment that delivers heat to the SMAS layer deep within the skin using ultrasound energy to stimulate new collagen production. Its core feature is that it stimulates the very fascial layer that surgeons pull during a facelift, without having to use a knife. It was developed by Merz, a US company, approved by the FDA in 2009, and has also cleared the Korean MFDS approval.

The effect does not appear immediately after the procedure, but starts to show in stages after 2 to 3 months, and reaches its peak at 3 to 6 months. The duration is usually about 1 year to 1 and a half years. Frankly, there is some pain. On a scale of 1 to 10, the average is 5 to 7 points, and it can feel like 7 to 9 points in areas close to the bone, such as the cheekbones or jawline. Therefore, anesthesia options are almost always required.

📌 Core Summary: Ultherapy is an FDA-approved ultrasound lifting targeted at the SMAS layer. The effect gradually appears after 2 to 3 months, and the pain is at an average level of 5 to 7 points.

🔬 What exactly is Ultherapy?

The official technical classification of Ultherapy is MFU-V (Microfocused Ultrasound with Visualization). It is based on HIFU (High-Intensity Focused Ultrasound) but differs from regular HIFU in that it fires energy while directly viewing the skin cross-section with ultrasound imaging.

The principle is as follows. When ultrasound energy is focused on one point, a **thermal coagulation point (TCP) of about 60 to 70°C** is formed, and this heat contracts collagen and simultaneously induces neocollagenesis. While the skin surface remains completely fine, remodeling occurs only on the inside.

Depth is adjusted with cartridges.

FDA-approved indications are brow lifting, submental (under-chin) & neck lifting, and improvement of décolletage (upper chest) wrinkles. Surprisingly, many people do not know that the décolletage is included.

📌 Core Summary: Ultherapy is an MFU-V device that delivers heat up to the SMAS layer (4.5mm) while viewing with imaging. The brow, neck, and décolletage are officially approved areas.

⏳ When does the effect appear, and how long does it last?

This is the point most frequently misunderstood. Ultherapy is not a treatment where you look in the mirror on the day you receive it and say 'Wow.' Right after the procedure, there is only a slight pulling sensation, and even that is brief.

The real change follows the time it takes for new collagen to fill in. The contours start to get refined from 2 to 3 months, and the maximum effect is reached around 3 to 6 months. Therefore, if you have a wedding or an important event, it is correct to receive it at least two months in advance.

The duration of the effect is roughly 1 year to 1.5 years, with large individual differences. Since skin aging continues, it cannot be permanent, and it is a concept of managing it with periodic re-treatments. If you want an immediate and physical pull, thread lifting may be more appropriate; if sagging is severe, a facelift may fundamentally be a more definitive answer. Ultherapy can be seen as a procedure that fills the intermediate gap where 'surgery feels too burdensome.'

📌 Core Summary: Effects become apparent after 2 to 3 months, peak at 3 to 6 months, last for 1 to 1.5 years, and require periodic re-treatment.

😣 How much is the pain, and how can it be reduced?

You cannot talk about Ultherapy without mentioning pain. As the energy goes deep, it is accompanied by a stinging and tingling sensation.

Looking at it on a 10-point scale, it is roughly as follows:

• Low-energy areas: 3 to 5 points

• Average feel: 5 to 7 points

• High-energy areas near bone (cheekbones, jawline, forehead): 7 to 9 points

The closer it is to the bone, the more the vibration is transmitted directly, making it feel more painful. Thus, anesthesia almost always comes as a pair. Choosing among anesthetic cream, nerve block anesthesia, and sleep anesthesia according to your situation will significantly reduce the perceived pain. Those sensitive to pain tend to prefer sleep anesthesia.

There is something that must be pointed out here. Pain and effectiveness are not proportional. It does not mean results get better just by blindly firing strongly and heavily. What is more important than the number of shots (or lines) is the accurate depth, energy, and design. Typically, 300 to 900 shots are used for the entire face, and more than 800 to 1200 lines are used when treating the face and neck together, but this number itself does not guarantee quality. The treatment time is around 1 hour including anesthesia, and the quick return to daily life due to almost zero downtime is a clear advantage.

📌 Core Summary: Pain averages 5 to 7 points, and 7 to 9 points near bones, which is controlled with anesthesia. Rather than the number of shots, accurate depth and design determine the outcome.

⚖️ What is the difference between Thermage and domestic HIFU?

When researching Ultherapy, you will inevitably compare it with Thermage. The two have complementary relationships with different roles rather than being rivals.

If you want to pull up sagging skin, Ultherapy is right; if overall elasticity and fine wrinkles are your concern, Thermage is appropriate. Therefore, many people choose the 'Ulthermage' combination, where both treatments are received together.

Domestic HIFU devices such as Shurink or Doublo are also frequently compared. The cost-effectiveness is definitely attractive. However, Ultherapy differs in precision—as it directly checks the layer using ultrasound imaging during irradiation—and in consistency as it uses genuine cartridges from Merz. Rather than one being the absolute right answer, it is a matter of choosing according to your budget and goals.

📌 Core Summary: Ultherapy (Ultrasound/SMAS) is for lifting, and Thermage (RF/Dermis) is for elasticity, meaning their roles differ, and receiving them in combination is also common.

⚠️ Side Effects and Contraindications

The most frequently mentioned side effects are cheek hollows and fat atrophy. If excessive energy is fired on thin individuals with little facial fat, the already scarce cheek fat may decrease, making them look more hollowed. Therefore, for thin faces, the energy setting and area design must be approached conservatively.

There are also cases where it is better not to receive the treatment:

• In case of pregnancy or breastfeeding

• In case there are metal implants in the treatment area

• Right after dental treatment, or if there is inflammation/wounds in the treatment area

• In case of a high risk of scarring, such as a keloid constitution

Conversely, it is a well-suited procedure for those in their late 30s who are beginning to worry about mild sagging and find surgery burdensome. Ultimately, what determines the result is the practitioner's skill level rather than the device. Even with the same Ultherapy, customer satisfaction varies greatly depending on who designs it and how.

📌 Core Summary: Cheek hollows in thin faces are a representative side effect, and pregnant women, metal implants, and those right after dental treatment should avoid it. The practitioner's skill level is key.

✅ How to Verify Genuine Ultherapy and Combined Treatments

Be sure to check if it is genuine. Merz's genuine cartridge is structured to lock automatically when the designated number of shots is used up, so reuse is impossible. It is good to ask if you can directly check the genuine cartridge and equipment before the procedure.

Combined treatments are also common. While Ultherapy is strong in capturing sagging, it cannot perfectly fill in nasolabial folds or volume loss. It is natural to complement this part with fillers, facial expression wrinkles with Botox, and skin texture and moisture with skin boosters.

However, there is a sequence. It is common to receive Botox/fillers after a certain period of recovery post-Ultherapy. Since thermal energy can affect the distribution of fillers, Ultherapy is normally performed first, followed by fillers and Botox after going through a recovery period. For specific timing, it is safe to consult with medical staff based on the treatment area and your condition.

📌 Core Summary: Verify genuineness with Merz cartridges that automatically lock upon consumption of shots, complement nasolabial folds and volume with fillers and Botox, but maintain the sequence.

Frequently Asked Questions

How much is the pain of Ultherapy and how can it be reduced?

On a 10-point scale, it can feel like an average of 5 to 7 points, and up to 7 to 9 points in areas close to local bones like cheekbones and jawlines. You can significantly reduce pain by choosing among anesthetic cream, nerve block, and sleep anesthesia.

When does the effect start to appear and how long does it last?

It is minimal right after the procedure, starts to show in earnest from 2 to 3 months, and reaches its maximum at 3 to 6 months. The duration is usually 1 year to 1 and a half years, with significant individual differences.

Does a higher number of shots guarantee better results?

No. Pain and effectiveness are not proportional, and precise depth, energy, and design determine the outcome more than the number of shots. Excessive treatment can rather increase the risk of cheek hollows.

Can cheek hollows occur if I have a thin face?

If excessive energy is irradiated on a face with little fat, cheeks may look hollowed due to fat atrophy. For thinner faces, energy and treatment areas must be designed conservatively.

What is the difference between Ultherapy and Thermage, and can I receive them together?

Ultherapy is strong in lifting by stimulating the SMAS layer with ultrasound, while Thermage is strong in elasticity by heating the dermis with RF. Since their purposes differ, the 'Ulthermage' combination is also common.

How do I check if it is genuine Ultherapy?

Merz's genuine cartridge automatically locks once the set number of shots is depleted, preventing reuse. Inquire beforehand if you can directly verify the genuine cartridge and equipment before the procedure.

Who should not receive Ultherapy?

It is recommended to avoid if you are pregnant/breastfeeding, have metal implants in the treatment area, right after dental treatment, or have inflammation/wounds in the treatment area.

When can I receive Botox and fillers after Ultherapy?

Usually, Ultherapy is performed first, and after a recovery period, Botox and fillers are carried out. Since thermal energy can affect fillers, it is safe to discuss the specific timing with medical staff.
