Yes! The Prime is IPX7 approved which makes it 100% waterproof. You can use in the shower or the bath. We would recommend not to immerse fully under water for more than 30-40 minutes.
You can either apply cleanser directly to the Prime or to your skin. It is a personal preference; the Prime will work either way.
You can either use the thermal eye massage in a stationary position or with gentle motions to move around the eye area. It truly depends on what is most comfortable for you.
The Prime has been designed with an automated 2-minute timer for both the modes. The 2-minute cleansing mode is sufficient for a facial cleanse. For the heated eye massage, we recommend to split the 2 minutes between both eyes.
We recommend you wash the brush surface with soap and water, rinse with clean water and pat dry.
