The sponsorship forms part of a six-month partnership with Look to create excitement around Smashbox Cosmetics, as it expands its presence in the UK.
The multi-platform campaign was created by IPC Creative and the media planning and buying was handled by M2M.
One of the main features of the partnership will be a Smashbox Cosmetics virtual shopping wall at The Look Show, where consumers can purchase products using an augmented reality phone app from Blippar.
Smashbox Cosmetics will appear on the catwalk, with the brand creating the new season's beauty looks modelled at the show.
The magazine itself will be enhanced with an augmented reality app, which allows readers to shop for the various make-up looks and products featured in the show.
The Smashbox Cosmetics campaign will run throughout the summer to mid-December, and aims to introduce Look's readers to the key studio-inspired benefits of the brand and its "hero" products. Magazine features, print and online display advertising, social media and homepage takeovers also form part of the partnership.
Quita Davis, general manager for Smashbox Cosmetics, said: "We know that our Smashbox Cosmetics fans love fashion and beauty, and we see the opportunities to link with key fashion brands, as well as sharing what we know about makeup that will have everyone looking flawless for their flashbulb moment, wherever that is, as a really great opportunity."
Julie Lavington, Look publishing director, said: "Look readers have a veracious appetite for beauty and the Smashbox Cosmetics brand is perfect for them. This partnership is all about creating excitement and theatre around Smashbox Cosmetics, and will have readers raring to try it out."
Look magazine also recently launched the 'Look What I'm Wearing' campaign which allowed readers to take photos of what they were wearing and upload the pictures onto the magazine's website.
