Overview
A 5.24 fl oz (155 ml) hydrating essence toner from Secret Key built around galactomyces ferment filtrate and adenosine, part of the brand's Starting Care line.
Galactomyces ferment filtrate is a fermented ingredient commonly used in Korean skin care to support a more even looking complexion, and adenosine is included alongside it here. The listing describes the product as an essence toner, a step that sits between cleansing and moisturizing in a multi step routine.
