Marula oil is pressed from the nuts of the marula tree, native to southern Africa, and is rich in oleic acid along with natural antioxidants.
It is prized in skincare for absorbing quickly without feeling greasy while still providing a good amount of moisture. Research into its composition has found meaningful levels of antioxidant compounds that can help defend skin cells against the kind of oxidative stress caused by UV exposure, supporting its traditional reputation as a protective, anti aging oil.
Clinical safety testing on marula oil has found it to be well tolerated with a low risk of irritation, though large scale trials measuring specific anti aging outcomes are still limited.

Our team reviews ingredient research and uses up-to-date evidence to rate ingredients based on the categories below.
Best
Ingredients with the most rigorous and convincing evidence. These are the standouts backed by consistent findings across independent, peer reviewed clinical research.. When we call an ingredient Best, it has earned that distinction through genuine, reproducible proof that it improves skin.
Good
Reliable, well tolerated ingredients that do their job without complaint. They may not carry the headline benefits of a Best rated active, but they hydrate, stabilize a formula, or support the ingredients around them in ways that make a real difference in how a product performs and feels.
Average
Ingredients that are perfectly safe and serve a clear function, typically as an emollient, thickener, or filler, but do not offer any meaningful skin benefit beyond that basic job. Not a red flag, just not a reason to choose one product over another.
Bad/Worst
Ingredients with documented potential to irritate skin, disrupt the barrier, or trigger sensitization in some users, often synthetic fragrance, drying forms of alcohol, or certain essential oils. Not automatically a dealbreaker for every skin type, but worth knowing about before you commit to a product.
