Suitable for

All skin types but especially sensitive and those with chronic skin issues such as acne, rosacea, and eczema.

Why we stand behind it

Powered by a concentrated dose of stable hypochlorous acid, a heroic anti-inflammatory and anti-bacterial, this intensive skin-saving serum is on a mission to help soothe and purify chronically sensitive skin (acne, rosacea, eczema etc.) and strengthen the skin barrier. It has received the National Eczema Association Seal of Acceptance, showing its efficacy and safety for sensitive skin.

Key ingredients

Hypochlorous acid: A natural compound produced by the body′s immune system. It acts as an anti-inflammatory and antibacterial agent, helping to soothe and purify the skin while reducing redness.
Water and sodium chloride: Creates an isotonic solution that mimics the composition of our own bodies, allowing for optimal delivery of hypochlorous acid.

The Credo Clean Standard™

Every product we offer meets our industry leading standards for safety and sustainability.

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:


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.


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.


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.
