Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level
emergingThe ingredient may be promising, but claims should be treated more cautiously.
What it is
A cold-pressed or solvent-extracted oil from the leaves or stems of the Oxalis hedysaroides plant, a tropical species in the wood sorrel family.
How it works
As an emollient, it sits on the skin's surface to soften and smooth by filling in gaps between skin cells. Its antioxidant content may help neutralize free radicals that cause premature aging, but this effect is not well-studied for this specific oil.
Pros
Lightweight feel
Unlike heavier oils, Oxalis hedysaroides oil absorbs quickly without leaving a sticky residue, making it suitable for daytime use.
Novel antioxidant source
The oil contains natural antioxidants that may help protect skin from pollution and UV-induced stress, though more research is needed to confirm potency.
Cons and cautions
Scarce research
There are no peer-reviewed studies on this specific oil's effects on human skin, so its benefits are largely theoretical based on related species.
Potential allergen
As a rare botanical, it may cause unexpected allergic reactions in some users, especially those with plant allergies.
Best for
- People looking for a lightweight, natural oil for daily moisturizing
- Those interested in trying rare botanical ingredients with antioxidant potential
Use caution if
- Anyone with known allergies to Oxalis or wood sorrel family plants
