The first thing to know about Nécessaire’s deodorant is what’s not in it: The soft stick is free of aluminum, baking soda, ozokerite, parabens, PEGs, and silicone. What is in it: mandelic acid (an AHA), niacinamide, and pantothenic acid. These skin-loving ingredients are swirled into the sunflower wax base to deliver clean odor protection that lasts (and lasts). Choose from fragrance-free or eucalyptus; the latter mixes its namesake note with Siberian fir, lavender, and ginger for a refreshing subtle scent that’s a little earthy and a little herbaceous.
