What it is and why it's in the formula
Jojoba oil (Simmondsia chinensis) is technically a liquid wax that closely resembles skin's own sebum, which is why it's a favorite in fast-absorbing formulas. It helps the mist sink in cleanly rather than sitting on the surface, supporting the 'no greasy residue, socks go on right after' experience the product is built around.
Where it fits in the full formula
Jojoba Oil is one of 16 ingredients disclosed openly on the PureNail Pro label — none of the formula sits behind vague "proprietary blend" wording. You can see the complete breakdown, including which oils pair with it, on the full ingredients page.
