For a 'test lab' feature, we often pass a product or gadget around the office for a mildly scientific poll. But as the first to get my hands on Kiehl's latest pimple potion, I decided I'd handle this one myself. In truth, I didn't want to give it up. Part of the company's 'Dermatologist Solutions' line, the salve contains a patented Lipo Hydroxy Acid cooked up by a team of Kiehl's white-coats. I applied the cream—to a red zit and then a small bump that I feared might be developing into one—after my morning shower and then at night before bed. Almost instantly, the redness had faded and the size of the bump was diminished, working faster and more effectively than the handful of prescription formulas I've tried in the past. Maybe their doctors know something mine didn't. $30, at Kiehl's.
