‘Isn’t this conversation supposed to be happening the other way round?’ I quipped, though we were in the middle of a field at about 4 in the morning. It was fair cop that one of the world’s leading make-up artists didn’t have any make-up to hand.

Since then, Tilbury has made sure she’s never more than a click away from a black eyeliner – or anything else for that matter. Her make-up range Myface.cosmetics, which launched in Boots last October, is now available on her new website myfacecosmetics.com.

As you can imagine when a world-renowned backstage make-up artist launches her own line, expectations rode very high. But her range, which in keeping with its digitally-inspired name is designed to resemble iPods and iPhones, didn’t disappoint. The ‘Mymix’ foundation, £12.71, and ‘Blingtone’ eye shadow, £9.78, (see what she’s doing with those names?), flew in to our Top 50 Beauty Heros list back in January and they’ve made regular appearances in ELLE staffers make-up bags ever since (I’ve got the concealer, £7.82, in mine).

Now, to celebrate the launch of the website, Myface are offering ELLE readers 30 per cent off all purchases made from the site before next Wednesday. Web Beauty Assistant Amy Lawrenson and Myface fan, tells us why it’s worth a look:

‘Like the make-up, this stylish, easy-to-navigate website is pretty much foolproof. Anyone who’s already discovered Myface knows that the make-up is split in to three ranges, fair, medium and dark, because, as Tilbury explains, ‘All too often I see women wearing the wrong shades of blusher, lip stick, etc for their skin tone. Without your own personal make-up artist, it's easy to end up choosing the wrong shades. Myface makes it simple because we've created complete colour palettes for each skin tone… I know from experience that these colour palettes are foolproof.’

‘These colour palettes form the blueprint for the site, and once you’ve established whether you’re fair, medium or dark, you can purchase accordingly – I loved the way you can zoom in on products just by clicking on them – as well road-testing your booty on catwalk-grade looks, thanks to fair, med and dark interpretations of different CT creations.

‘The site also includes how-to videos, Tilbury’s own blog, which we’re told will be regularly updated with news and tips, and even her beauty Gospel (think the 10 commandments of make-up, though there are actually only nine). Now, we’re not ones to tie ourselves to any one view – the world of beauty is far too undulating for that – but given the girl’s been at it for 17 years, we think they might be worth reeling off every now and again.

‘Repeat after me: “I will always match my concealer to my foundation.”’
