Marula oil has occlusive properties that prevent loss of water from the skin and exerts moisture-retentive properties. It has been shown to inhibit the activity of elastase and collagenase, which prevents the normal acceleration of skin aging.
Marula oil is an extract from the Sclerocarya birrea nut made of multiple mixed fatty acids. These fatty acids have anti-aging, moisturizing and hydrating effects, performed in part by inhibition of enzymes that would normally degrade proteins in the extracellular matrix.
Marula oil is likely safe for all skin types and tones based on available data. It has been reported to be non-irritating, so it is unlikely to cause reactions in patients; however, patients with previous reactions to this extract should be cautious with use.
There is minimal data on contraindications for the topical application of marula oil.
