DND Gel + Lacquer Duo #437 Blue De France

437 Blue De France gives you a navy blue and a wet-look gloss in one bottle. Blue is high contrast against most skin tones, so a clean cuticle line matters. DND lists it as a subtle jelly like deep blue.

What you get in the bottle

• Thin coats, full colour: DND 437 Blue De France rarely needs a third pass, which keeps the set flexible and less prone to lifting at the stress point.
• Wear you can quote a client: about three weeks on the DND base gel and top coat, cured under LED.
• Take-home match included: the lacquer in this duo is the same shade, so a chip on day twelve is a two-minute fix at home.
• A range worth standardising on: over 1,200 DND gel shades means the wall grows without a second system to learn.

Specifications

Application steps

1. Prep: file to shape, push back the cuticle, buff off the shine and dehydrate the plate.
2. Base gel: one thin coat of DND base gel, cap the free edge, cure under your LED lamp.
3. Colour coat one: one thin coat of DND 437 Blue De France, keep it off the skin, cure.
4. Colour coat two: a second coat evens out the pigment, cure again.
5. Top coat: one coat of DND top coat, cure, then wipe the tacky layer if your top coat leaves one.
6. Lacquer at home: the matching lacquer goes over a base coat and air-dries, so the client needs no lamp.

Where this shade gets booked

• Summer sets: blue is high contrast against most skin tones.
• Pairing work: it sits next to a silver chrome or a white swirl.
• Toes, where a glossy finish is what the client asked for.

Which option should you add to the bag

On this page you are choosing between DND 437 Blue De France in different formats. Gel Polish & Lacquer is the matched gel and lacquer pair, so the client can take the polish home in the same shade. Gel Polish Only is the gel bottle on its own, for salons that only run gel services. Lacquer Only is the air-dry lacquer on its own, no lamp needed. Gel & Lacquer + Base Top is the duo bundled with a base and top coat, useful when you are opening a new station. Gel & Lacquer + Dipping Powder is gel, lacquer and dip powder together, so one shade covers all three services. Most reorders are the plain duo, because the base and top coat outlast any single colour. The DND 437 Blue De France bundles are worth it the first time the shade enters the wall, not on the third reorder.

Storing the bottle

Keep DND 437 Blue De France upright with the cap tight and out of direct sunlight, because daylight will start curing gel in a half-empty bottle. Wipe the neck before you close it so the cap does not seize. Pigment-heavy and glitter shades settle between services, so roll the bottle between your palms rather than shaking it, which puts bubbles in the first coat and shows up under the lamp.

DND 437 Blue De France is stocked alongside the full DND gel and lacquer wall, the whole gel and lacquer category and DND starter sets.
