Question: If Kathleen has five new toners, four moisturizers, three cleansers, six anti-aging eye creams, and five serums to test this week, how many different skin-care combinations does she have? The answer: Something I used to know how to calculate, back when the SATs were still scored out of 1600. But this math problem is not unlike what I do week-to-week. For some consistency and to figure out which products really do work, I switch out different variables while keeping some products as constants to test their effects. This was how I discovered Estée Lauder's Revitalizing Supreme Global Anti-Aging Creme, which made my skin feel impossibly soft and moisturized each time. Unlike most fancy face creams that feel like fluffy creams or gels, Lauder's cream feels almost like an occlusive moisturizer, with the texture of a lighter Nivea. It goes on a little thick and doesn't melt into your skin immediately, but the next morning, your skin will feel "I can't stop touching it" soft.
