Why we stand behind it
This clean, stain-free serum deodorant features a unique AHA blend that keeps you from smelling, but also visibly brightens the darker under arm area and helps with ingrown hairs. No aluminum. No baking soda. Only skin-nourishing ingredients.
Key ingredients
AHA blend for clean chemistry: Helps create a pH environment where it′s harder for the bacteria that causes body odor to survive.
Shikimic acid: a natural deodorizer derived from Star Anise.
Mandelic acid: a gentle AHA derived from bitter almonds that supports cell turnover to help address dullness and discoloration.

What is an undertone?
An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:
Pink/Cool
I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.
Neutral
I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.
Yellow/Warm
I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.
