Jojoba oil is commonly used in skincare, especially for oily skin types. Its use is supported by some scientific evidence, though robust clinical data are limited. Jojoba oil is actually a liquid wax ester, closely resembling human sebum in composition. This similarity allows it to be absorbed easily by the skin without clogging pores, making it “non-comedogenic.” Several in vitro and ex vivo studies indicate that jojoba oil possesses anti-inflammatory and skin barrier-repairing properties. A small clinical study published in Complementary Medicine Research (2012) found that clay masks containing jojoba oil improved acne lesions, which are often associated with oily skin. Additionally, jojoba oil may help regulate sebum production by mimicking natural skin oils, potentially signaling to the skin to produce less sebum. Its antioxidant and antimicrobial properties may further support its use in oily and acne-prone skin.
However, while these mechanisms are promising, larger and higher-quality clinical trials specifically examining the effects of jojoba oil on oily skin are lacking. Most of the evidence is based on laboratory studies, anecdotal reports, and its well-tolerated profile in cosmetic formulations. Thus, while jojoba oil is widely used for oily skin and some scientific rationale exists, the strength of clinical evidence currently remains modest.
