At ARO, we’re flipping the script on deodorant.

Why try to mask odor when your underarms don’t have to smell in the first place?

Powered by glycolic acid, ARO is the first-of-its-kind deodorant designed to prevent odor, not cover it. From postpartum hormonal shifts, athletes in the locker room, or patients after underarm Botox, ARO supports bodies in every season.

How does it work? Odor-causing bacteria thrive in higher pH environments. By gently lowering the pH of your underarms, ARO creates a more acidic environment - making it harder for those bacteria to survive. The result: odor prevention before it even starts. 

ARO Underarm Spray is acid-based, so it works a little differently than traditional deodorant. Here’s how to get the best results:

  • LESS IS MORE

    ·       Start with 2–3 sprays on clean, dry underarms

    ·       Use 3–4 times per week, while your skin adjusts

    If you feel any discomfort or sensitivity, skip a day and resume using every other day.

  • Just like any new skincare product, your body needs to adjust. So, give it a week as your pH rebalances.

    When switching to an acid-based deodorant (especially from aluminum-based or heavy fragrance products), it’s normal to go through a short adjustment phase. You may notice minor irritation if overused early on.

  • SKIP ON SHAVING DAYS

    Avoid applying ARO directly after shaving. Like any acid-based product, freshly shaved skin may be more sensitive and prone to irritation.
