Experienced my first uberlather. I had just received my first tube of Proraso and I had bought some pure glycerin, having previously been using VDH Deluxe. Although still learning to generate a luxurious lather, my skills have been improving. Today I applied some Proraso to my face and rubbed it in with my fingers. Then I loaded up my brush as usual with the VDH and began face lathering. I never needed to add any glycerin, the lather just exploded. Perhaps the Proraso would have done that on its own. Fantastic shave!
