Does ONDA PRO Hurt? Cooling & Downtime

5 November 2026

What does DEKA ONDA PRO® 2.45 GHz Coolwaves® feel like? How 5°C sapphire contact cooling prevents surface pain, what side effects to expect, and why downtime is 0.

If you have ever experienced the sharp, hot snap of older monopolar radiofrequency or deep ultrasound devices, it is natural to ask before booking: 'Does ONDA PRO® hurt, and what are the side effects?' At Minori Skincare in NoMad, Manhattan, comfort is one of the top reasons guests choose DEKA ONDA PRO® 2.45 GHz Coolwaves® — sessions require 0 numbing cream, 0 needles, and 0 recovery days.

Why is a 2.45 GHz Coolwaves® session so much more comfortable than surface-heating RF? Two physics mechanisms work together: first, at 2.45 GHz, electromagnetic energy passes through the upper epidermis with minimal resistance so roughly 80% of the energy is absorbed deeper in the subcutaneous layer and 20% in the dermis rather than scorching the skin surface; second, every Pocket, Shallow, and Deep handpiece integrates a continuous 5°C contact-cooling system that chills the outer skin throughout the 30-minute pass.

What does it actually feel like, and what are the normal temporary post-visit effects? Guests describe the sensation as a cool metal glide on the surface paired with a gradual, deep warming sensation underneath — similar to a warm-stone massage. Immediately after your 30-minute $350 session, the treated area may look mildly pink or flushed and feel warm to the touch for 1 to 2 hours as local circulation increases, and deep body work can occasionally leave mild temporary tenderness the next day.

Who should avoid ONDA PRO®, and what does the FDA clearance cover? During your pre-treatment consultation, we screen for contraindications including implanted electronic devices (such as pacemakers), metal implants in the treatment zone, pregnancy, and active skin infections. Under FDA 510(k) K260647 (cleared as SPECCHIO by DEKA M.E.L.A. s.r.l.), the device is FDA cleared for heating for the purpose of elevating tissue temperature for selected medical conditions such as temporary relief of pain, muscle spasms, and increase in local circulation — and, via the massage device, a temporary reduction in the appearance of cellulite.
