Jojoba oil has 2 beneficial effects on skin which speeds up true tanning from the sun and slows down redness. (which means you get tanned without getting as red)

Effect A: It reflects away radiation due to its reflective surface, hence it slows down your erythemal response (redness).
Effect B: The refractive properties allow UV to penetrate through the corneous layer (outer protective skin layer) and reaches the inner skin layer much easier.

Oh I almost forgot, jojoba oil has a good moisturising property as it is chemically close to our own sebum (naturally produced oil on our skin)
