What it does

It’s rich in fatty acids and has tiny traces of retinoic acid. Those traces are why people call it a 'natural retinoid', but the amount is far too small to act like one. It softens skin and supports the barrier. It works best as a last-step oil over moisturizer at night.

The EU’s ingredient database lists it as an emollient (gives skin a soft, smooth look).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗

The evidence, graded

moderateÁcsová et al. (2021), at a Slovak university and the Czech public health institute, tested 14 plant oils. Rosehip seed oil measured SPF 2.6 on people, and the oils overall gave no or negligible protection. Tamanu oil stood out only in a lab test, at SPF 11.2. Popiół-Adamska et al. (2026), at Jagiellonian University, measured tamanu oil at SPF 21.5 in a lab test, falling to 5.2 after light exposure, and concluded plant oils can't replace UV filters.Ácsová 2021 · Photochemical and Photobiological Sciences ↗
