Plinia Cauliflora Fruit Extract

Plinia cauliflora (jabuticaba) fruit extract is primarily an antioxidant/soothing botanical used at low percentages, but it contains polyphenols/anthocyanins and other plant constituents that can sting or trigger irritant or allergic contact reactions in reactive or eczematous skin. While not a classic high-risk sensitizer like fragrance, the limited standardized patch-test data for this specific extract and variability between suppliers warrant a mild score, especially in compromised skin or when layered with other actives. Safety Notes: In commercial leave-on skincare (serums, creams, masks), Plinia cauliflora (jabuticaba) fruit extract is most commonly used as a supportive antioxidant/soothing botanical at very low inclusion levels (~0.01–0.1%), reflecting typical supplier-recommended use rates for fruit/polyphenol extracts and the fact it is often one of many botanicals in a blend. Higher-strength consumer products marketed around jabuticaba/“Brazilian berry” actives (single-hero botanical serums/ampoules, concentrated gel-creams, and some rinse-off masks/scrubs) can reach ~1–5% extract, with the upper end limited by solubility, color/odor impact, polyphenol-driven stability (browning), and potential tack/irritation in leave-on formats.
