Do I have to use the serum?Updated a year ago

The short answer is - absolutely not. The purpose of serum is to enhance the treatment. If you feel that it is not easy for you to move the treatment head over the skin - putting a thin layer of the serum of your choice, will definitely solve that. Besides that – there is a heat mode that is accompanying the treatment, so expect the blood circulation to increase and that will in turn improve the absorption of any vitamin-rich product that you chose to use. We recommend that whatever you chose to use – has a rather thin consistency and does not clog the device. Just make sure to wipe it off after the treatment.
