Onda Coolwaves Full Face: What Is the Appropriate Number of Kilojoules?

Onda Coolwaves Full Face: What Is the Appropriate Number of Kilojoules?

2026-07-23 • Patient Resources & Tips

Hello! This is Seye clinic, dedicated to all aspects of beauty.

"Doctor, how many ā€˜thousands of joules’ should I get for Onda Coolwaves Full Face? I'm worried it might be too strong…"

We often hear this question in consultations. Many people refer to the strength of Onda Coolwaves in terms of the number of 'lines' or 'thousands of joules,' but the actual standard is the energy unit kJ (kilojoule). Today, we will guide you on how to customize your energy settings based on your face, without being influenced by sheer numbers.

What Does 'Thousands of Joules' Mean in Onda Coolwaves?

Onda Coolwaves is a procedure that uses microwaves (not focused ultrasound) to safely address facial contours and improve firmness at the same time. Much like how a microwave heats moisture inside food, the microwaves from Onda Coolwaves minimize energy loss at the epidermis and are preferentially absorbed by fat cells. As a result, heat is focused on the dermis and subcutaneous fat layers, promoting collagen contraction and fat reduction. Here, ā€˜thousands of joules’ does not refer to lines but denotes the quantity of energy, with 1 kJ = 1,000 joules. At Seye clinic, we use a 3 mm handpiece for surface tightening and a 7 mm handpiece for deeper layers, such as the Double Chin, allowing for individualized planning.

Energy (kJ): How Much Is Suitable for Each Face Type?

The appropriate amount of energy is customized based on face size and the amount of lower facial fat – typically 40 kJ, 60 kJ, or 80 kJ.

Case

Recommended kJ

Joules Equivalent

Recommended For

Narrow Jawline

40 kJ

40,000 J

Small faces, young women, etc.

Average Face

60 kJ

60,000 J

Those with standard jaw/facial structure

Wide Lower Face/Men

80 kJ

80,000 J

Men, faces with thicker fat layers

Tailoring energy to each client’s actual facial structure helps promote safety and satisfactory results.

Duration & Sensation: What Are the Results and Experiences of Onda Coolwaves?

Onda Coolwaves is associated with minimal discomfort, with most patients reporting only a mild warming sensation during treatment. Many notice changes immediately after the procedure, and there is virtually no downtime, allowing for immediate return to daily activities, including washing and applying makeup. This can be a good option for those who want to improve both fat reduction and skin firmness at the same time. However, a higher energy setting does not automatically guarantee better outcomes—personalized planning is essential.

Q&A with the Doctor

Q. What exactly does ā€˜thousands of joules’ mean in Onda Coolwaves?

A. ā€˜Joule’ is an energy unit itself. Onda Coolwaves is based on the total energy (kJ) delivered, not the number of shots.

Q. What is the suitable kJ for the Full Face?

A. For women, typically 40–60 kJ (40,000–60,000 J) is used, while for men or those with a wide lower face, up to 80 kJ (80,000 J) may be customized.

Q. Does receiving more joules (energy) result in better outcomes?

A. Higher energy may help with fat breakdown and skin firmness, but more is not always better—customizing the dose based on individual conditions is important.

Q. Is it possible to return to daily activities immediately after treatment?

A. Yes, there is virtually no downtime and you can resume your daily routine right away.

Why Do Outcomes Vary with the Same Onda Coolwaves Procedure?

At Seye clinic, we do not rely on guesswork. Using EVE LAB precision diagnostics and 3D facial data analysis, we assess facial fat distribution and thickness. Based on these findings, we personalize handpiece depth (3 mm / 7 mm) and energy (kJ) for each client. Our Key Opinion Leader (KOL) medical team directly oversees counseling and the entire procedure process, ensuring skilled planning leads to better outcomes.

In Conclusion

With Onda Coolwaves, it is not just about using higher energy, but about carefully planning kJ based on your contours and amount of facial fat. Don’t focus solely on numbers—consult a professional to find the best approach for you. This has been the chief director of Seye clinic. Thank you.
