For home use, a non-invasive device like this 4-in-1 cavitation, RF, and vacuum machine can be a safer option than invasive fat-removal procedures when used correctly. However, no fat-reduction device is completely risk-free. Please start from the lowest intensity, apply enough gel, keep the probe moving, and do not use it on dry skin, broken skin, bony areas, or areas with implants or metal materials. This device is designed to support body contouring and skin firming, but it does not replace medical fat-removal treatments. If you have any medical condition, pregnancy, implants, or recent surgery, please consult your doctor before use.  

We recommend using a water-based ultrasound gel or conductive gel with this machine. Apply enough gel before treatment so the probe can glide smoothly on the skin. Do not use the device on dry skin. For RF and cavitation treatments, gel is recommended; avoid thick creams or alcohol-based products.  

This machine may help improve skin firmness and support facial contouring over time, but it does not replace fillers. Fillers are used to add volume, while this device is designed more for skin tightening, firming, and body/face contouring support. If your main concern is mild skin laxity, the RF facial head may help with consistent use. If you have significant volume loss, deep folds, or sagging, please consult a licensed aesthetic professional to decide whether fillers or another treatment would be more suitable.  

Bonjour, nous sommes désolés pour ce problème. Veuillez d’abord vérifier que le tuyau du vacuum est bien connecté, que le filtre est installé à l’arrière de la machine, et que l’intensité du vacuum est bien réglée. Vous pouvez aussi tester l’aspiration en plaçant la main sur l’embout. Si l’aspiration ne fonctionne toujours pas, veuillez arrêter d’utiliser la machine et nous envoyer votre numéro de commande ainsi qu’une courte vidéo du problème à [service@freyara.com](mailto:service@freyara.com). Notre service après-vente vérifiera votre demande et vous proposera une solution, échange ou remboursement selon votre situation.  

The machine does not emit one fixed temperature, and it does not have a temperature setting or display. The RF head gradually produces a warm sensation, and the actual skin temperature varies depending on the intensity, treatment time, movement speed, and amount of gel used. Please start at the lowest intensity, apply sufficient conductive gel, and keep the handpiece moving continuously. It should feel comfortably warm, not hot or painful. Stop immediately if you feel burning or excessive heat.  

For facial treatment, we recommend using the facial RF head for approximately 10–15 minutes per session. Apply a suitable conductive gel, start at the lowest intensity, and keep the treatment head moving continuously. Please do not use the 40K cavitation head or vacuum massage head on the face. 

The four small white filter pads are spare filters for the vacuum suction handle, designed to prevent oil, moisture, or debris from entering the machine. The two very small round plastic pieces are typically spare seals for the vacuum port/handle, used to maintain consistent suction. 

It can be used on the double chin area, but we recommend using only the small facial RF handpiece; do not use the large cavitation handpiece or vacuum suction handpiece on the neck or throat. 

Product page specification shows: Input: 110–240V; Output: 24V / 2A. 

Essential oils, lotions, creams, and gels are all fine. We’ll be adding our own products to the selection soon. For now, you can use your usual favorites.
