Try PinkyParadise, they specialize in circle lenses buy have a huuuge selection if Japanese and Korean cosmetics and most of the time they have really good description of the products, and you can easily find out if any of them contain whitening agents. Candy Doll, Eyemazing, Canmake, Dolly Wink and Melliesh are all very nice. Shu Uemura does excellent foundations without whitening properties, but are a bit pricier though easier to find.
