LUSH Full Of Grace Facial Oil Versus Selfless by Hyram Niacinamide & Maracuja Daily Support Moisturizer

Those are medium-chain fats which is why it melts fast on skin and feels lighter than stearic-heavy butters like shea or cacao.

In skincare, this butter works as an emollient and a temporary occlusive that helps soften the skin's surface and slows water loss.

Just to be upfront: there's no published human clinical trials on this ingredient and everything known about how it behaves on skin is from the fatty acid composition + general body of data on refined plant oils. At this time, marketing claims about wrinkles, elasticity, or "deep repair" are unsupported.

Industry survey data shows concentrations between 0.001%-7% for leave-on products and rinse-off products are capped around 0.2%.

No one has tested murumuru butter for comedogenicity in humans; the comedogenic ratings floating around trace back to lauric and myristic acid scores from the 1984 rabbit ear assay.

The author of that study later said that testing on rabbit ears is not ideal and human testing found that comedogenic ratings cannot predict how a finished formula will behave. It all comes down to formula, concentration, and your skin.

Malassezia is lipid dependent and feeds on free fatty acids between C11-24 chain lengths. This ingredient is made up entirely of chains in that range, so it may not be fungal acne safe.
