If you are using original Skull Shaver then you can only do dry shave. This was our first model and it comes with the engraved name as SKULL SHAVERTM on the shaver handle/body. Our other models allow you to shave wet or dry, with or without shaving cream or foam. Pitbull, Butterfly Kiss, and Palm shavers are also IPX5 water resistant, so you can safely shave in the shower. However, please do not fully submerge any of our shavers.
