What the Science Says
Jojoba oil is a liquid wax pressed from the seeds of the Simmondsia chinensis shrub. It is most commonly used as a topical skin ingredient and as a carrier oil in drug delivery formulations. A small clinical trial found it may reduce nasal itching when applied inside the nose, and it has been used as a vehicle to deliver psoriasis medications more effectively to the skin.
What It Doesn't Do
Not proven to reduce pain or improve skin integrity on its own. No evidence it works better than other oils for preventing perineal tears during childbirth. Not a proven treatment for psoriasis by itself — it was the drug carrier, not the active ingredient. No evidence for any internal health benefits when taken orally.
Evidence-Based Benefits
May reduce nasal itching when applied topically inside the nose.

Absorption & Bioavailability
Unknown for systemic use. As a topical agent, it penetrates skin and has been shown to enhance drug delivery into skin layers. At high concentrations, cell culture data shows dose-dependent cytotoxicity to nasal epithelial cells.
Red Flags to Watch For
- Cell culture studies show jojoba oil kills nasal epithelial cells in a dose-dependent manner — high-concentration nasal use may not be safe long-term
- Most studies use jojoba oil as a placebo or carrier for other drugs, not as the active ingredient — marketing claims often overstate its standalone benefits
- The nasal pruritus trial had no control group and only 46 male participants — results cannot be generalized
- No standardized dosing exists for any topical or oral application
