Like many wet shavers, I love menthol. I never had exposure to mentholated shaving cream until I returned to wet shaving, as canned foam was my choice. It’s cooling, refreshing, and great for summertime heat. The first mentholated cream I tried, Proraso green, overwhelmed me. I thought it was too chilling.  Now, I use products like Vostok, and Yeti Snot, and don’t find Proraso bracing at all.  Obviously that sounds like tolerance to a substance, so I began investigating it’s chemistry, and pharmacology.
