DND Gel Polish - 437 Blue De France
Couldn't load pickup availability
DND #437 Blue De France is a subtle jelly like deep blue from DND's original gel and lacquer line, the one with more than 1,000 numbered shades. Choose the gel alone, the gel with its matching lacquer, or the lacquer on its own.
What you get
- Gel Polish Only: one 0.5 fl oz (15 mL) gel bottle
- Lacquer Only: one 0.5 fl oz (15 mL) air-dry lacquer
- Gel Polish & Lacquer: the gel bottle and the matching lacquer, 0.5 fl oz (15 mL) each
Why techs stock it
- A system you already run: it works with DND Base #500 and DND Top #600, and with DC or DIVA base and top.
- Up to three weeks of wear: when it goes on over a base gel and under a top gel, cured layer by layer.
- Soak-off gel: the gel removes with acetone, which keeps the natural nail in better shape between sets.
- Natural-nail look: the sheer finish lets some of the nail show through, good for clean-girl sets.

Who it suits

- Clients who ask for subtle jelly like deep blue by name or by number 437.
Which option to choose
Choose Gel Polish Only if you only run gel services, Gel Polish & Lacquer if you also do pedicures or sell take-home bottles, and Lacquer Only for regular polish services. All three are the same Blue De France shade.
Removal
File through the top coat, then soak in acetone for about 10 to 15 minutes and ease the softened gel off with a pusher. Skip the drill on the natural nail and finish with cuticle oil.
More to pair with Blue De France: DND gel colours, DND blue shades and DND, DC and DIVA base and top gels.
Frequently Asked Questions
Does the lacquer match the gel exactly?+
Yes. DND mixes DND #437 Blue De France as a gel and a lacquer with the same shade number, so a gel manicure and a lacquer pedicure match. The lacquer air-dries, the gel needs an LED or UV lamp.
What colour is Blue De France?+
DND #437 Blue De France is a subtle jelly like deep blue with a sheer finish. Screens show colour differently, so check a swatch stick against the client's skin before the full set.
How long do I cure each coat?+
Under an LED lamp, cure each thin colour coat 30 to 60 seconds; a UV lamp takes about 2 minutes. Thin coats cure all the way through, thick ones do not.
Which base and top coat should I use?+
DND recommends DND Base #500 and DND Top #600 No Cleanse. DND, DC and DIVA base and top gels are cross-compatible, so any of them will work.
