The BeautyLive site (beauty live.msn.co.uk) was developed by MSN and digital agency Textuel\La Mine, part of the TBWA group. It aims to drive people to L'Oreal's web sites.
The web site features links contained within editorial on subjects that range from beauty secrets to the art of attraction and retail therapy.
Users can also sign up to receive beauty alerts, such as detox programmes or skincare regimes, via MSN Messenger or by email. Content is being generated by L'Oreal.
The BeautyLive channel is being promoted with editorial on the homepages of MSN and Messenger, and with banners and skyscrapers on MSN channels such as Women's, Love and Horoscopes.
The deal has been signed for 12 months but it is likely to be long-term, said Chris Ward, commercial director at MSN. "All deals are subject to contract, but we see this as a long-term partnership," he said. "The site allows L'Oreal to promote and upsell its entire range, including products for men."
Currently, the beauty company is concentrating on its Lancome and Maybelline brands.
