Why we stand behind it
The only hypochlorous acid serum recognized by all three leading U.S. skin health organizations—Eczema, Rosacea, and Psoriasis—it’s powered by a concentrated dose of hypochlorous acid to visibly reduce breakouts, redness + calm irritation. This water-based treatment is pH balanced (4.5), alcohol-free, fragrance-free and safe to use all over the body.
Key ingredients
- Hypochlorous Acid: Naturally produced by the body's immune system, it's anti-inflammatory and antibacterial properties help defend your skin from harmful bacteria, reduce redness, and soothe irritation.
- Water and Sodium Chloride: Act as the optimal delivery solution for hypochlorous acid.

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.
