I have been using designer brand deos ever since puberty, starting with Boss Black I believe, having moved through most Boss and Calvin Klein variants since, with the occasional Bulgari, Davidoff, Miyake, Armani, RL/Polo and more. (Yes, definitely an aquatic period in there, but that's about the only 'trend' I can detect, scent wise.) Having cycled through a few lower cost, less parabens, alcohol and aluminum versions, now, I cannot seem to find any that really are effective. A couple of those I have tried have seemed to INCREASE perspiration, in fact. Believe that was the deo cream from Kiehl's. MenScience Advanced Deodorant worked quite well for a while then seemed to wane in effect. I stay away from the white ones due to the discolouration most of these cause on tops. It also seems to me that the ones with alcohol in fact are more effective? Suggestions, gentlemen? Ideally obtainable outside of the UK but there's always that interweb. And it needs to be stick, mind you, not roll-on. A decent one I tried a while back was DR Harris Windsor, come to think of it.
