Evening Primrose Oil
INCI: Oenothera Biennis Oil
What is it?
A seed oil from Oenothera biennis, rich in gamma-linolenic acid, commonly marketed as a skin-barrier-supporting ingredient for sensitive and eczema-prone skin.
What does it do?
According to PubMed, a clinical review of oral supplements for atopic dermatitis found inadequate data to confirm evening primrose oil's efficacy, concluding that topically applied emollients remain the safest and most effective natural option -- an honestly-reported inconclusive finding rather than the strong barrier-repair claim often made in marketing (this study evaluated oral supplementation, not topical application).
