"My biggest gripe about wearing sunscreen is that it always seems to pill under my foundation. It drives me crazy! Lately, though, I've been using this Sobel Skin Rx Plant Stem Cell Day Cream + Sunscreen SPF 30 ($72) from NYC-based dermatologist Dr. Howard Sobel, and it's been a life-, er skin-, saver. It's packed with plant stem cells to help regenerate the skin and has SPF 30 to keep me protected from UV rays. I love that it's a physical sunscreen made with 15% zinc oxide that somehow doesn't leave a hint of white cast, and it never pills! I'm sold." — Lindsey Unterberger, content director, Makeup.com
