Our super-effective deodorants control body odor for up to 48 hours. We use food-grade ingredients that are safe and gentle for sensitive underarm skin. Unlike the other clean deodorants out there, we never use any aluminum, toxins, gluten, allergens or synthetic fragrances. Our skin-safe Sensitive Formula is baking soda free (made with magnesium & zinc) – to keep you odor-free and dry all day. All Starling formulas glide on dry and are guaranteed to NOT stain your clothing!
