MAC is a backstage staple - this we know. We watch them very carefully for trend tip offs every season and try to uncover new secret launches to report back to you. These game-changers slipped beneath our radar though, because backstage nail artist Marian Newman is good at hiding things.

Having done their shows and campaigns for years, Marian has been working on a permanent line for MAC for a little while now, and wanted to specifically bring sophisticated nail art to the forefront, directly relating her line back to the make-up authority so ingrained in the MAC brand.

The result? Nail Transformations. A line of six nail 'cosmetics' that can alter your own nail colours in any number of ways. Transformative, you see?

Our pick is Shadow, a sheer formula that takes nail colour down a tone or two to make it slightly 'off', so you can subvert any colour. Highlight does the opposite, allowing any colour to pop a little more, then there are nail 'pigments' to give different flashes of light - pink, green and gold, while texturiser gives an antique leather effect.

This line is not about following the trends, but altering them in your own vision, and we thank Marian Newman for the genius thought.

Nail Transformations launch 4th July for £10 each. Visit maccosmetics.co.uk
