Rosa Rubiginosa Fruit Extract

Rosa rubiginosa (rosehip) fruit extract is typically used as an antioxidant/skin-conditioning botanical at low percentages, but as a plant extract it contains multiple bioactive constituents that can trigger irritation or allergic contact dermatitis in reactive or eczema-prone skin. Clinical patch-test and real-world dermatology experience show botanicals are a common source of unpredictable sensitivity, especially when layered with other actives, so a mild (not “gentle”) risk rating is warranted for patient safety. Safety Notes: In commercial skincare, Rosa rubiginosa (rosehip) fruit extract is most often used at very low levels (trace to ~0.1%) as a marketing/antioxidant botanical in emulsions, toners, and cleansers, especially when supplied in glycerin/propylene glycol and added near the end of the INCI list. Higher-strength OTC leave-on serums, facial oils, and barrier creams that are positioned around “rosehip” can reach ~1–5% when the material is a true extract (not the pure seed oil), with practical upper limits driven by color/odor, stability, and solubility rather than specific regulatory caps. Rinse-off products typically stay at the low end because contact time is short and higher loads can negatively impact fragrance/color and surfactant system stability.
