Aro Underarm Spray

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

Instead of clogging pores and covering up smell, ARO underarm spray works like medical- grade skin care.

Powered by Glycolic Acid, it gradually lowers your skin’s pH, creating an environment where odor-causing bacteria can’t survive.
Why does that matter? Because odor doesn’t come from sweat itself – it comes from bacteria. By creating a more acidic environment, aro makes it harder for those bacteria to thrive, helping prevent odor before it even begins.

While traditional deodorants rely on aluminum, baking soda, or heavy fragrance to block or mask odor, aro takes a science-first approach.

Did we mention it’s unisex? Just an effective deodorant that works with your body – not against it.

How to use

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

Start with 2–3 sprays on clean, dry underarms. Less is more (especially at first).
Use 3–4 times per week while your skin adjusts.
Just like any new skincare product, your body needs to adjust. So, give it a week as your pH rebalances. Avoid applying ARO directly after shaving. Like any acid-based product, freshly shaved skin may be more sensitive and prone to irritation.

Note
Patch test before use. Avoid broken or irritated skin.
Do not use immediately after shaving. For external use only.
