Yes it is well known here that Jean-Paul Guerlain said racist remarks about black people ! But the saddest of all it that the Guerlain family has no heir. In other words, LVMH chose a nose all Guerlain perfumes : Thierry Wasser. Thierry Wasser created Guerlain Homme l'Eau ( very good ), La Petite Robe Noire ( very mainstream ) or Lys Soleia.
This has nothing to do with the make-up artistic Direction though. Guerlain perfumes used to be masterpieces ( Jicky, L'Heure Bleue, Après l'Ondée, etc.. ) but they all were reformulated by the so called IFRA which controls everything from A to Z ( to create " safe " perfumes ). Such restrictions are controversial, perfumistas do not agree with those new formulas and noses must abide by the laws. As far as make-up is concerned the most important is the artistic direction and very often ( all the time ) the Artistic director must follow the instructions from LVMH.
Jean-Paul Guerlain was a great nose like his brilliant ancestors before him, one of the most creative nose of the times but yes he did say wrong things about black people and he was fined for this.
if anyone has swatches of these two, please holla!
