If your grandmother is Estee Lauder and you grew up in a household where the dinner table conversation revolved around skin care, what is the one cosmetic product you couldn't live without? 'Daywear Super Antioxidant Complex, a fantastic moisturiser,' Aerin Lauder replied without even a thought. In town last week, Aerin's duties as Estee Lauder director of creative product development include studying trends on the fashion runways in Paris, Milan and New York and translating them into make-up colours. 'And it's not just fashion from where I get my inspiration. I get it from the art world and from nature,' says Aerin. Married to an investment banker, Aerin says she likes the quiet life and when she is not travelling, enjoys seeing friends and sleeping - a beauty tip she picked up from her grandmother.
