There is a big difference between cosmetics and skin care products. Cosmetics just cover over problems, while skin care products work to keep skin healthy. Kiehl’s deals exclusively in skin care. The brand began in New York City’s Lower East Side as a single shop in 1851, and moved into developing its own skin care products in 1921. It opened in the Czech Republic in 2014 and now has two locations in Prague, at malls in Nový Smíchov and Chodov, as well as online sales.
