I went today and they said it is recomended that you wear lotion right before you go in cause dry skin will reflect the light. Can I use any kind of lotion. I don't want to use the fancy shit that they were trying to sell me cause of the frangrance and don't want my pores clogged. Also I am FRing so I think it would be bad to expose your glans to that so I wore my cone, is that alright?
