Collection: Teintes Unies

This is the full colour range rather than a fixed pairing, so you choose exactly the shades you want, and the discount grows as the basket does: 15% off two shades, 20% off three, 25% off four and 30% off five. Buy one on its own to top up an empty bottle, or put five together for the biggest saving. If you would rather take a ready-made pairing, the Duo and Quad bundles live in gel nail polish sets, and you can browse by colour family in gel nail colours.

Getting the best from a single shade

Apply over a base coat in two thin coats, curing each for 60 seconds, then seal with a top coat. Deeper shades usually reach full opacity in two coats; sheerer pastels and brights may want a third thin layer. If you love mixing, pick a few singles and build your own palette rather than buying a preset bundle.
