The short version

An underarm spray that works like skincare.

ARO is powered by glycolic acid. Rather than blocking sweat or covering odor with fragrance, it helps bring the underarm toward a more acidic surface — a less hospitable environment for the bacteria involved in odor.

How to use

Acid-based, so it works a little differently.

01

Spray

2–3 sprays on clean, dry underarms.

02

Let it dry

Give it a moment before dressing.

03

Start slow

3–4 times per week while your skin adjusts.

04

Adjust

Increase or decrease based on what works for your skin.

New to acid-based deodorant? Less is more at first. Give your routine about a week to settle in. Do not apply immediately after shaving — freshly shaved skin can be more sensitive.

Patch test before use. Avoid broken or irritated skin. For external use only.

Ingredients
