About

An astringent bark powder from Eastern Hemlock — rich in tannins that tighten skin and control excess oil, commonly used in natural skincare formulations.

Tsuga canadensis (Eastern Hemlock) bark contains condensed proanthocyanidins and hydrolysable ellagitannins that provide astringent and antioxidant activity. The bark has a history of use in traditional medicine for skin conditions. Tannin-rich botanicals can cause dryness or irritation in sensitive or reactive skin types when used at high concentrations.
