The included syringe is for applying/filling conductive gel between the 4.5mm main probe and the 2.0mm or 3.0mm depth regulator. It is **not for injection into the skin**. Please **do not remove the clear film/sticker from the regulators**. The transparent area is part of the regulator and is used to check that the gel is fully filled with no air bubbles before treatment. Make sure there is enough gel between the probe and regulator before use.  

At the moment, we do not have a verified English tutorial video link available for the FacialDefy 2.0 Pro. For use, apply enough conductive gel to completely cover the treatment area, keep the probe in full contact with the skin, and move it slowly and evenly upward during operation. Add more gel whenever it begins to dry. If you would like additional operation guidance or available tutorial materials, please contact service@freyara.com. 

There is no fixed number of centimeters specified for one full beep cycle. The manufacturer recommends keeping the probe fully in contact with the skin and moving it slowly and evenly upward throughout the cycle. Do not hold the probe stationary on one spot, and make sure there is always enough conductive gel for smooth movement. Because an exact “cm per cycle” speed has not been specified, we do not recommend using 3cm or 10cm as a fixed rule. If you need an exact technical movement rate for your treatment protocol, please contact service@freyara.com 

The device begins outputting HIFU energy immediately after you press the Start button. Energy is delivered during the series of short beeps while you move the probe slowly and steadily over the skin. The final louder beep indicates that one complete shot/cycle has finished — it is not the only moment when energy is emitted. Keep the probe in full contact with the skin, use enough conductive gel, and continue moving it slowly throughout the entire beep cycle. 

Please do not remove either the black or transparent films/stickers from the 2.0mm, 3.0mm, or 4.5mm heads. They are part of the probe/sealing structure and should remain in place during use. For the 2.0mm or 3.0mm head, apply a thick layer of gel to the 4.5mm main probe first, then attach the depth adapter. Make sure there are no air bubbles or gaps in the gel before treatment. If any film is already loose, damaged, or punctured, please send a photo to service@freyara.com before using it. 

The optional heads are used for different treatment depths. Use the 2.0mm head for more superficial areas, such as fine lines and thinner facial skin. Use the 3.0mm head for general facial tightening. Use the 4.5mm head for deeper lifting areas, such as the cheeks, jawline, and lower face. Please always apply enough conductive gel, start at the lowest intensity, and keep the probe moving slowly upward. Do not use directly on the eyelids, eyeballs, open wounds, inflamed acne, or areas with implants or fillers.  

Hello, please contact us via Facebook or email. We can better assist you with videos and pictures. 

No, it does not dissolve facial fat. HIFU mainly tightens and lifts the skin by boosting collagen. 

This device does not use RF (radio frequency) technology; you can check the instructions. We have clearly stated this. 

Yes. HIFU 2.0pro can help reduce fine lines around the mouth by stimulating collagen production in the deeper layers of the skin. With regular use, the skin around the mouth appears firmer and smoother. This should be avoided on the philtrum area.
