Myrciaria Dubia Fruit Extract

Myrciaria Dubia (camu camu) fruit extract is primarily used as an antioxidant/brightening botanical and can contain naturally occurring acids (including vitamin C-related components) and other low–molecular weight compounds that may sting on compromised or eczematous skin at typical cosmetic use levels. Human irritation data for this specific extract is limited and batch-to-batch variability is common with fruit extracts, so while many tolerate it, reactive individuals can experience burning or redness—warranting a mild (not “gentle”) irritancy score for patient safety. Safety Notes: In commercial skincare, Myrciaria Dubia (camu camu) fruit extract is most often used as a botanical antioxidant/brightening support at very low levels (around 0.01–0.1%) in serums, creams, and cleansers where it functions primarily as a label/claims ingredient within a broader extract blend. Higher-strength consumer products (typically leave-on masks, booster serums, and “superfruit” ampoules) can use ~1–5% of standardized glycerin/propylene glycol/water extracts, with the upper end (~10%) seen in niche/high-claims formulas that rely on the extract rather than pure ascorbic acid; actual effective vitamin C delivery depends heavily on extract standardization and solvent system.
