Ribes Nigrum Seed Oil

Ribes Nigrum (black currant) seed oil is an emollient lipid blend rich in linoleic acid and gamma-linolenic acid, typically used at a few percent up to higher levels in moisturizers; as a non-volatile, non-acidic oil it is generally well tolerated and can support barrier function. However, like other botanical seed oils it contains minor components that can trigger irritation or allergy in a small subset of highly reactive/eczema-prone patients, and oxidation of unsaturated lipids can increase sting/dermatitis risk over time. Given broad tolerability but non-zero sensitization/irritation potential in compromised skin, a gentle (not exceptionally gentle) score is most consistent with patient-safety data. Safety Notes: In mass-market leave-on creams/lotions/serums, Ribes Nigrum (Black Currant) Seed Oil is frequently used as a minor emollient/omega source at very low add levels (~0.01–0.1%) when part of a broader botanical oil blend or for label-claim support, and it also appears in rinse-off products at similar trace levels. At the high end, it is sold directly to consumers as single-ingredient facial/body oils where it can be 100% (neat oil), and it is also used at high levels (roughly 10–50%) in anhydrous balms and oil serums; no specific EU/FDA concentration cap applies beyond general cosmetic safety and stability/oxidation constraints.
