Marula Oil

Sclerocarya Birrea Seed OilBarrier

A rich last-step oil for dry to very dry skin. It’s high in oleic acid, which can feed the yeast behind fungal acne.

What it does

It’s mostly oleic acid, with vitamin E and a pleasant feel, and suits dry to very dry skin as a last oil layer. It’s not the best pick if you get fungal acne (small, itchy, same-size bumps), since oleic acid can feed the yeast behind it.

The EU’s ingredient database lists it as a humectant (helps hold in moisture).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗

The evidence, graded

expert consensusFungal acne is Malassezia folliculitis — an overgrowth of a yeast already living in normal skin flora, commonly mistaken for ordinary acne. In a culture dish the yeast grows only when fatty acids longer than C10 are added, because it cannot make its own. That is why Drop holds lipid-rich products back while you have this flagged. No source Drop has read tested an oil on skin, set an upper chain length, or showed squalane, MCT or mineral oil to be safe.Rubenstein 2014 · Journal of Clinical and Aesthetic Dermatology ↗
