Risks & Warnings
Generally well tolerated, but any plant oil can cause individual sensitivity. May feel heavy for very oily or highly acne-prone skin. As an unsaturated oil, it can oxidize if poorly formulated or stored, which may increase odor or irritation potential. Oral evening primrose supplements have separate safety considerations and should not be confused with topical cosmetic use.
