strong evidenceDermatology and cosmetic literature describe jojoba as a well-tolerated emollient with sebum-normalizing and barrier-supportive effects, useful even on acne-prone skin when used moderately.
On a label: usually effective at 2-20%.

What is known, and what is missing
Measured on: Barrier support and sebum normalisation on oily or acne-prone skin - the two jobs this row scores and markets; neither has a dated human onset.
The scored benefit is barrier support (7), with sebum balancing named as a primary function and hydration only 4, so those are the outcomes a timeline has to answer for. Neither has a controlled human onset. The wax esters do soften and smooth the surface the moment they are spread, mixing into existing sebum, and that deposit is real - but it is a film that leaves with the next cleanse, so it is not the barrier repair or oil normalisation the ingredient is bought for, and timing it would answer the wrong question. The most-quoted human study is an uncontrolled prospective observational pilot of a clay mask containing jojoba oil, used two to three times weekly for roughly six weeks with self-reported grading; the clay, the masking effect and the absence of a control make both the jojoba contribution and its timing unrecoverable. Treat both scored outcomes as untimed.
No controlled onset trial identified for either barrier or sebum outcomes. The clay jojoba-oil facial mask study (Forsch Komplementmed, 2012) is an uncontrolled observational pilot - described here, not cited by PMID, and not adequate to support any bucket. The on-contact softening is wax-ester physical chemistry, not a measured endpoint.
