In the West, Japanese cosmetics have developed quite a devout following, so it might come as a surprise that in Japan, women are actually becoming more interested in South Korean beauty products and treatments.

At Japan's first-ever Cosme Tokyo fair, South Korean companies made a strong showing, taking the top slot among the non-Japanese exhibitors. In addition to shiny eyeliners, sparkling eye shadows, bright blushers and other makeup items, they presented crowd-drawing snail-slime moisturizers and synthetic snake-venom face packs.

Like K-Pop and Korean TV dramas, the popularity of Korean cosmetics has been undeniable for the past few years. And as South Korea has become a popular tourist destination, Korean cosmetic companies have begun to realize that Japanese tourists were perhaps some of their best customers. While it’s not all going to Japan, one thing is certain: Korea's cosmetic exports climbed $600 million in 2010, up from $80 million in 2001.
