Hi dear, thank you for the question. No, I didn’t use anything. Although it’s water proof so I think u can use it if you’d like but I don’t think u need anything. You can just use it dry.
My hair dresser told me those shavers are not made to remove long beard like yours . He said that if the hair is long to trim it first with a normal shaver and with this one you can shave closer to the skin and maintain it day by day .
