Although the name sounds slightly scary, no - this isn't where you go to get lips the size of Kylie Jenner's. But what you can get is (in our minds) better - lips exactly the same shade as Kylie's - or absolutely whatever colour you choose.
How does it work? Simply take a seat at The Lip Lab's counter, describe what you're looking for (by all means bring pictures or items from your wardrobe to match with) and watch as your consultant creates your custom blend using pigments and micas right in front of you. As well as the shade, you choose the finish, flavour (we went with mint, but the more exotic options include Parisian Rose and Pink Champagne) and extras like SPF and plumping agents. The colour is then heated, cooled and moulded in as little as 15 minutes while you wait - might we suggest creating your own custom lip gloss to pass the time.
The damage? A helluva lot less than you usually spend in these parts - lipsticks are $45 a pop; lip glosses $25.
