I have tried tons of Clarins skincare and was lucky enough to attend their education class and I think their strongest line is their body line - oils, anti cellulite body cream, hand cream...
Also I currently use their Double serum, Multi active day and night creams, exfoliator, eye cream,cleanser, toner.... I like them. I think they invest a lot in research and also combine best from newest technology and best from plant extracts.
Makeup I did not try anything.
