I've continued to buy and rebuy these for years for a reason! They're so effective — glycolic acid + salicylic acid to exfoliate, along with Vitamin K + Bilberry extract to promote a more even skin tone. After you wash your face at night, rub one of these single-use towelettes all over your face, neck, and chest. Simply follow with a nighttime moisturizer! I love how they combine so many must-have ingredients into one simple step. Plus, they're so easy to travel with. No need to pack a bunch of night serums or worry about travel sizes!
