No. It should not be painful to use. You should always start at Level 1 and work your way up to build up tolerance. If you go straight in at Level 4, you will get a shock!
We have had a couple of people with fillings who have mentioned it is less comfortable over areas where they have them, and have chosen to avoid those areas. This is thought to be caused due to the presence of metal in the mouth (either braces or amalgam fillings), which will conduct the electric current and can stimulate the nerve endings. If you don't have fillings, we are aware that some users can find the sensation quite strong, especially in comparison to other microcurrent products they may have used. Normally this sensation subsides after the first few uses.
There is a difference in the current strength between MAGNITONE LiftOff® and some other devices available. Ours operates at a slightly higher level than others which means you can feel the current a little more, but it also means that your facial muscles are responding to it much deeper, in the same way they would with any Electrical Muscle Stimulation device. What you should feel is a pulsed sensation - this is often barely noticeable but it can feel like small electric shocks that can cause the facial muscles to twitch whilst the product is in contact with the skin. However, it shouldn't cause pain or prolonged discomfort or restricted movement after use. If the sensation is painful on the lowest setting, then you may wish to discontinue using it.
Alternatively, try switching from our Superconductive Gel to a normal moisturiser or serum, or to no gel at all. The oil base in normal moisturisers can help to dampen and block the current, meaning it penetrates less well into the skin and may be helpful for you to build up use from.
