Distinctive in its color and known as “Japan blue,” Japanese indigo has long been regarded for its deeply soothing, restorative, and calming powers. The plant’s extracts help comfort irritated skin, while its ingredients help support the skin barrier. During the Edo period in Japan, samurai wore a layer of indigo-dyed cotton beneath their armor to help heal injuries, and the rich dye was also used for traditional firefighter uniforms and presented to newborns in the form of a blanket—a symbolic testament to its protective qualities.
In addition to its eye-catching hue, Japanese indigo’s active ingredients help provide anti-inflammatory relief. Tryptanthrin is a nitrogen-rich compound known to help flush away toxins and irritants, and indirubin is a dynamic isometric compound that supports skin’s natural barrier function.
This timeless botanical acts as a shining example of both natural beauty and gentle efficacy, the cornerstone of Tatcha formulas. The Indigo Collection was born from a desire to soothe and calm, from skin to soul.
