If you are interested in looking at websites that sell Japanese make-up, I found a post/list on Musings of a Muse that may help you out. Be warned - make-up is a totally different thing in Japan, and a lot of products wont be the consistency or have the effect that you may be used to if you are accustomed to Western make-up - it's all part of the fun really! :) If you have any questions I'll do my best to answer - but I'm not that knowledgeable on Japanese make-up either :P
I'm still yet to try the big brands like RMK, Addiction, Cle de Peau, Shiseido and Paul & Joe - but they are just so bloody expensive :P I'm a pretty hardcore drugstore girl when I'm back in Japan ;P
Have you tried any Japanese cosmetics/skincare?
Which is your favourite? :)
