Kiehl's is an American beauty institution that started as a small pharmacy in the East Village. The first concoction sold was the Love Oil (now known as Musk Essence Oil). Men's products were the next launch, and even Andy Warhol was a fan at one time. Today, the brand is dedicated to philanthropy work and creates special products to profit AIDS research, like its new nail polish project.
