Four formulas can feel like a puzzle, so let's make it simple. Three of them share the same zinc active. What changes is what sits alongside it, how the base feels, and what your skin can take.
Core is the everyday one at $22. Max is the biggest formula at $32. Sensitive is for skin that reacts, also $32. Tea Tree is the botanical original at $25.
Start here: what's your priority?
Core is the simple one. Fifteen ingredients, one oil, magnesium hydroxide up front with the zinc active alongside it. The finish is dry and matte. It costs less than Max because it's made of fewer things.
Max carries more of the zinc active than Core does, with magnesium in support, on a four-oil base with a slip agent that takes the drag out. Twenty-six ingredients.
Sensitive runs the same zinc active but skips magnesium entirely, using triethyl citrate to work with your skin's acidity instead of nudging its pH. No baking soda, no alcohol. It's Dermatologist Tested. No sting, no burn, no grit. If irritation is your whole history with natural deodorant, start here.
Tea Tree is the original Zaffré®, and the one built differently: tea tree and sage botanicals with zinc oxide, on a baking soda base. It doesn't contain the zinc chloride hydroxide the other three share. If baking soda has ever burned you, buy Sensitive instead.
