What you get
- 1 x OPI F15 You Don't Know Jacques! Intelli-Gel gel polish, 0.5 fl oz (15 mL)
Why techs stock it
- Stays put: Intelli-Gel thins under the brush and self-corrects once pressure releases, so strokes level out instead of running into the cuticle.
- Controlled pick-up: the Intelli-Brush has a rounded edge for the cuticle line and releases gel gradually.
- Up to 3 weeks of wear: base, two color coats and top each cure in 30 seconds in the OPI Star Light.
- HEMA-free, TPO-free and vegan: made without added HEMA and with no animal-derived ingredients.
- Finish: One-color crème, so it reads the same under salon light and daylight.

How long do I cure each coat?+
Each coat of base, color and top cures in 30 seconds in the OPI Star Light. Keep coats thin and cap the free edge so the gel cures all the way through.
Is You Don't Know Jacques! HEMA-free?+
Yes. OPI Intelli-Gel shades are formulated without added HEMA, and the formula is TPO-free and vegan. Other acrylates are still in the formula, so check the ingredient list if a client has a known sensitivity.
