SUNDAY RILEY B3 Nice 10% Niacinamide Serum

Why you’ll love it: Unlike a lot of other potent antioxidant serums, B3 Nice doesn’t have an off-putting smell—rather, it doesn’t have any noticeable scent. Its milky texture feels oh-so-comforting on skin, dries down almost immediately, and doesn’t pill under moisturizer. Within a month, one editor saw dark spots along her hairline and around her mouth fade completely and says it transformed her dull, vampire-like complexion into a glowing one in as little as two weeks. Basically, it’s a skin-care miracle worker in a bottle, thanks to niacinamide (which evens skin’s tone and smooths its texture) and antioxidant EGCG from green tea. How you’ll use it: This serum can be used day and night. After cleansing, simply apply, seal in moisture with a face cream, and you’re good to glow.
