Sofwave results: how much can you actually expect?

Sofwave is a non-invasive lifting device that simultaneously fires 7 ultrasound parallel beams into the mid-dermis layer (approximately 1.5mm deep) to induce collagen and elastin production. The treatment takes about 30 to 45 minutes for the entire face, and there is virtually no downtime, allowing you to return to your daily life immediately after the procedure. The effects are gradually felt starting from 1 to 4 weeks, become distinct at 8 to 12 weeks, and usually peak around 3 to 6 months.

However, Sofwave is not a cure-all. Since it targets a shallow and precise depth, it is well-suited for early to moderate elasticity loss and fine wrinkles, but it is difficult to view as a treatment that can address severe sagging or fat reduction. In this article, we will coolly examine everything from its principles to its efficacy curve, differences from other procedures, and common misconceptions.

🔬 How does Sofwave work?

The core of Sofwave is SUPERB™ (Synchronous Ultrasound Parallel Beam) technology. As the name suggests, it is a method of irradiating 7 ultrasound beams in parallel and simultaneously. The frequency is in the 4MHz band.

The destination of this energy is about 1.5mm below the skin surface, the **mid-dermis**. At this depth, it creates a Thermal Coagulation Point of about 60 to 70°C, slightly denaturing the collagen, and starting the collagen remodeling process to fill that space. Over time, new collagen and elastin fill in, which is the actual principle behind the improvement of skin elasticity.

You might worry about the epidermis, but the SofCool™ cooling system cools the skin surface to about -4 to 0°C throughout the treatment. This structure concentrates the heat in the dermis while protecting the surface, reducing the risk of burns and pain.

📌 Key Summary: Sofwave is a treatment that uses seven 4MHz ultrasound beams to generate heat of 60 to 70°C in the 1.5mm dermis to regenerate collagen while protecting the surface through cooling.

📈 When does the effect of Sofwave start, and how long does it last?

The effects are not immediate. This is because it takes time for collagen to be newly produced. The general timeline is as follows:

• 1–4 weeks: Subtle changes in elasticity begin to be felt.

• 8–12 weeks: The period where lifting and wrinkle improvement become distinct.

• 3–6 months: The effect reaches its peak.

• 6–12 months: The improved state is maintained (subject to individual differences).

In clinical reports, the rate of improvement assessed around 12 weeks varies depending on the study. It has been reported as approximately 80% improvement for eyebrow and neck lifting, 86% in a study focusing on wrinkle improvement, and about 72% in a multicenter study involving various institutions. The wide range of these numbers ultimately means that results vary depending on an individual's skin condition and degree of aging.

One thing to make clear: the effects of Sofwave are not permanent. Even newly created collagen gradually decreases over time. Therefore, maintenance treatments every 6 to 12 months are usually recommended.

📌 Key Summary: Effects appear from 1 to 4 weeks, peak at 3 to 6 months, and last for 6 to 12 months; they are not permanent, so periodic maintenance is required.

⚖️ How is it different from Ulthera, Thermage, and Shurink?

This is the most common question in lifting consultations. Understanding that the energy modalities and target depths are different makes the choice much easier.

The key is the **SMAS layer (Superficial Musculoaponeurotic System)**. HIFU procedures like Ulthera and Shurink reach this deep layer to aim for strong lifting, but Sofwave does not reach this far. Instead, because it targets only the dermis above the fat layer, the relatively low risk of the cheek hollowing side effect is considered an advantage. This is also why people who do not have much fat on their face consider Sofwave.

Additionally, since Sofwave does not target melanin, it is relatively less affected by skin color. The honest conclusion is that no single procedure is absolutely superior; rather, the right treatment varies depending on the depth of sagging and skin condition.

📌 Key Summary: Sofwave targets the shallow dermis layer, while Ulthera and Shurink target the deep SMAS layer. HIFU is advantageous for deep lifting, while Sofwave is favorable for elasticity improvement with less concern about cheek hollowing.

✅ What are the FDA and MFDS clearances and indications?

The standard for gauging safety and efficacy is certification. Sofwave has received clearance from the US FDA 510(k) for multiple indications over time.

• 2019: Brow Lift

• 2022: Improvement of submental (under-chin) and neck laxity

• 2023: Improvement in the appearance of cellulite

In South Korea, a device must be approved by the Ministry of Food and Drug Safety (MFDS) to be used legally. This is why it is necessary to verify whether the equipment is genuine before the procedure. However, detailed lists of domestic indications or long-term tracking data are not yet widely disclosed, so it is better to have realistic expectations rather than overestimating the results.

📌 Key Summary: Sofwave has expanded its FDA approvals to include the brow (2019), submental and neck (2022), and cellulite (2023). In South Korea, the standard is to use MFDS-cleared equipment.

🙋 Who is a good candidate for Sofwave?

Sofwave is suitable for people like this:

• Early to moderate skin sagging and loss of elasticity

• Those who are concerned about fine lines around the eyes and mouth

• Those who want natural improvement without downtime

• Those who are worried about cheek hollowing due to low facial fat

Conversely, if the sagging is already severe, or if the goal is to reduce facial or double chin fat, there are clear limits to using Sofwave alone. Sofwave is not a fat-reduction treatment. In such cases, it is more reasonable to consider other lifting approaches together.

Onlif Clinic focuses on non-surgical procedures from a dermatological perspective, aiming to care for the nuances of skin concerns—ranging from elasticity and lifting to skin boosters, thread lifts, ultrasound HIFU, and radiofrequency RF. Instead of changing the shape of the eyes, nose, or mouth, our approach is to calmly address the signs of aging and sagging. This is also why we divide and assign procedures according to specialized areas, based on the belief that 'a single doctor cannot do everything perfectly.'

📌 Key Summary: It is suitable for early to moderate loss of elasticity and fine lines; if severe sagging or fat reduction is the goal, other approaches should be considered together.

⚠️ Common Misconceptions and Post-Treatment Precautions

First, let's clear up a few misconceptions.

• "Sofwave is a laser." → No, it is not. It is an ultrasound-based device.

• "The stronger the pain, the better the effect." → This is groundless. Even if discomfort is reduced through SofCool cooling, the result depends on the collagen response.

• "Lifting is done in a single session." → Collagen remodeling takes time, and maintenance is a prerequisite.

Common-sense care after the procedure is helpful.

1. Avoid heat irritation such as saunas, hot springs, and intense exercise for about 1 week.

2. If you have a history of fillers or thread lifts, be sure to inform your practitioner before the treatment.

3. Before-and-after photos must be taken under the same lighting and angle to compare changes accurately.

4. If you are pregnant or breastfeeding, consult carefully about whether to undergo the procedure.

📌 Key Summary: Sofwave is an ultrasound treatment, not a laser, and the intensity of pain does not guarantee effectiveness. It is recommended to avoid heat irritation for 1 week after the treatment.

❓ Frequently Asked Questions (FAQ)

When do the effects of Sofwave appear and how long are they maintained?

Subtle changes are felt starting from 1 to 4 weeks, become distinct at 8 to 12 weeks, and peak at 3 to 6 months. It is maintained for about 6 to 12 months thereafter, but since it is not permanent, periodic maintenance is recommended.

What is the difference between Sofwave and Ulthera (HIFU)?

Ulthera is a HIFU device that reaches the deep SMAS layer and is advantageous for strong deep lifting, while Sofwave precisely targets the shallow dermis layer at 1.5mm. Consequently, Sofwave carries a lower risk of cheek hollowing side effects.

Can Sofwave reduce a double chin or facial fat?

It is difficult. Sofwave is an elasticity and lifting treatment that targets the dermis, not the fat layer, so fat reduction is not its main purpose. If your goal is to lose facial fat or a double chin, it is better to seek consultation for other approaches.

Can I return to daily life immediately after the Sofwave treatment?

Yes. There is virtually no downtime, so you can return to your daily routine immediately after the treatment. However, it is best to avoid heat irritation, such as saunas and intense exercise, for about 1 week.

Is Sofwave a laser treatment?

No, it is not. Sofwave is a device that uses ultrasound in the 4MHz band. Because it does not target melanin, it is relatively less affected by skin color.

Can the procedure be performed on areas where fillers or thread lifts have been done?

It may be possible, but you must inform your practitioner of your history before the procedure. Since the approach can vary depending on the location and type of implants, disclosing this accurately during consulting is safe.
