However, it is worth noting that the more poles, the better. However, the less poles, the greater the strength of the rf beauty instrument, and the deeper the RF energy enters the subcutaneous tissue, the stronger the effect.

The reason is that the handpiece of bipolar (or multipolar) rf beauty instrument contains positive and negative electrodes, and its radio frequency energy will form a loop only when it is lost under the dermis, and will not go deep into the subcutaneous tissue.

In contrast, the radio frequency energy of a monopole rf beauty instrument, such as a children's eye focusing rf beauty instrument, directly penetrates the dermis, and then contacts the metal sheet through hands or other parts, forming a large loop.

The results of professional machine test show that unipolar RF can penetrate subcutaneous 10mm~20mm, while bipolar RF can only penetrate subcutaneous 2~4mm, and the difference is very obvious.
