First came the wave of manufacturing, with Samsung and LG; then the K-pop stars, whose ubiquity reached its regrettable height with Psy. Now comes the latest import from South Korea: a formidable array of beauty products.

It all started with the BB cream. In early 2011, the Korean brand Dr. Jart introduced two BB creams at Sephora in the United States. They had dermatologic roots, intended to protect and heal patients’ skin after treatment, and had been popular as all-in-one skin-care and makeup products in Korea for several years before they came to the United States.

The cream was a hit. Major beauty companies took note. Soon enough, it had spawned versions from L’Oréal, Smashbox, Clinique, Jane Iredale, Stila and Dior — and paved the way for a Korean beauty invasion of the United States.

The beauty market has long been led by European countries, which were thought to be the source of innovation. But in recent years, American women (and beauty companies), their interest piqued by the BB cream, began to look more closely at Korean multistep skin-care regimens, and they liked what they saw.
