Anogeissus Leiocarpus Bark Extract

Anogeissus leiocarpus bark extract is a polyphenol/tannin-rich botanical used mainly for antioxidant and anti-aging benefits, typically at low concentrations, but tannins can be astringent and sting compromised barriers. While widespread severe reactions are not well-documented, limited standardized patch-test data and the known irritancy potential of tannin-heavy extracts justify treating it as a mild risk for eczema-prone or post-procedure skin, especially in leave-on products. Safety Notes: In commercial skincare, Anogeissus leiocarpus bark extract (often supplied as a standardized anti-aging active in glycerin/propylene glycol) is frequently used at very low levels (~0.001–0.05%) in mass-market moisturizers and cleansers where it is a minor supportive botanical. Most leave-on anti-aging serums/eye products cluster around ~0.1–1%, while the highest consumer-available “booster”/concentrate-style formulations and some brand-actives based on vendor recommended-use maxima reach ~2–3% of the extract (as-supplied), typically in leave-on products; rinse-off uses are generally lower due to limited contact time. There are no specific FDA/EU maximum concentration limits for this botanical, so the upper end is driven primarily by supplier use-level guidance, stability, odor/color impact, and irritation tolerance.
