Is Thuja Orientalis Leaf Extract a Good Ingredient?
It rates Fair because potential astringency and conditioning are plausible, but clinical support is sparse, and leaf constituents such as volatile compounds can irritate or sensitize skin. That makes the benefits uncertain at levels strong enough to matter but still tolerable.
