About

A tannin-rich astringent from black spruce bark — tightens pores, controls shine, and provides antioxidant defense from polyphenols and stilbenes.

Picea mariana (black spruce) bark is rich in condensed tannins (proanthocyanidins), stilbenes including resveratrol analogues, and polyphenolic compounds. These constituents contribute antioxidant, antimicrobial, and astringent activity. Topical application is considered safe at cosmetic-use concentrations; the main concerns are potential dryness and irritation for sensitive skin types due to the high tannin content.
