What is the difference between 13.56 MHz and 27 MHz?

This is exploring the difference between high frequency technologies. It is important to understand the effects of specific radio frequencies in order to better identify the benefits and limitations of their use for permanent hair removal.

The reserved frequencies of 13.56MHz and 27MHz produce radiation, which safely generates enough localized heat in water-rich tissues such as human follicles. Both frequencies meet strict safety standards. However, the 27 MHz frequency has the advantage of a more efficient power absorption by water molecules. This means, that at 27Mhz, less power is needed to epilate a hair than at 13Mhz or, at equal power, the 27MHz will need less time to do so. Another important advantage of using 27MHz is the rapid positive to negative polarity changes, 27 million cycles (Hertz) per second. This frequency, that we call PicoFlash, distinguishes the Apilus Platinum from conventional 13.56MHz epilators by coagulating tissues twice as fast.

As well, extensive research has proven that at 27MHz the area of destruction is limited to within close proximity of the probe, where stem cells for hair re-growth are located. Dectro’s new Synchro modality takes full advantage of this precision to coagulate the cells responsible for hair growth in a concentrated manner. It delivers a very powerful 27 MHz signal, controlled in a very short timing cycle of milliseconds. In contrast, at 13.56MHz a wider heat pattern (up to three times greater) is produced and diffuses more deeply into the dermis causing a greater possibility of irritation.
