Tea tree and centella waters calm angry skin; mild, non-astringent community feedback.

What the community says

Backed by 55 studies

A lightweight serum built around 67% tea tree leaf water and 19% centella water, with niacinamide and allantoin. Redditors call it mild and calming for redness, though the strong tea-tree smell and flare concerns complicate daily use.
