Tasmannia Lanceolata Fruit/Leaf Extract

Tasmannia lanceolata (Tasmanian pepperberry) extract is used at low concentrations primarily for soothing/anti-redness claims, but it contains bioactive polygodial and other botanicals that can sting or trigger irritant or allergic contact reactions in highly reactive or eczematous skin. While many users tolerate it, botanical extracts have a non-trivial sensitization/irritation rate in patch testing populations compared with inert humectants/emollients, especially when layered with other actives. Given the potential for delayed sensitization and the need to prioritize worst-case safety in compromised barriers, this fits a mild irritancy classification. Safety Notes: In commercial skincare, Tasmannia lanceolata (Tasmanian pepperberry) extract is often used as a soothing/anti-redness botanical at very low levels (down to ~0.0005–0.01%) when supplied as a concentrated active (e.g., pepperberry/POGO-style standardized extracts) dosed for sensory and claims support in leave-on creams, serums, and sensitive-skin products. Typical mass-market use is commonly ~0.05–0.5%, while the upper end in consumer-available “high-strength” calming serums and targeted redness products reaches about 1–2% depending on the supplier dilution/standardization; higher than this is uncommon due to cost, odor/sensory impact, and potential irritation from pungent constituents. Rinse-off products generally sit toward the lower end because of short contact time, whereas leave-on products span the full range.
