Jojoba Oil
In plain terms
Technically a liquid wax rather than an oil, and one of the closest matches to skin's own sebum. It sits well on nearly all skin types, including oily and acne-prone, and reactions to it are very rare.
What the evidence shows
Jojoba oil is pressed from the desert shrub Simmondsia chinensis and is unusual: it is almost entirely wax esters, not the triglycerides of a typical oil, which makes its makeup remarkably close to human sebum. The CIR panel found it safe at concentrations up to 100%, non-irritating, non-sensitizing, and non-mutagenic, and across decades of use only a couple of contact-allergy cases have ever been reported. It forms a light, breathable layer that holds in moisture without sinking deep into skin, and lab work on human skin shows it can calm inflammation and support the barrier. Its comedogenic rating is low and its sebum-like profile makes it one of the friendlier oils for acne-prone skin. There is little to flag here: it is a gentle, stable, well-tolerated emollient. The one aside is that jojoba is for the outside only, since the seeds contain a compound that makes the raw plant unsuitable to eat, but that has no bearing on its use on skin.
On the label
Listed as simmondsia chinensis seed oil or jojoba. One of the safer picks for almost any skin type, including oily and sensitive. Nothing to avoid for the vast majority of people.
