Outhwaite, who has most recently been appearing in the BBC's military police drama 'Red Cap', is believed to being paid around 拢250,000 to appear in the ads.
In launching the campaign, Outhwaite told reporters that her mother used to be an Avon lady when she was growing up.
"The idea of surprising someone really interests me. Just turning up and seeing what happens, or going to an Avon party -- I'd be up for it."
The 32-year-old joins previous celebrities including tennis sisters Venus and Serena Williams and girl band Atomic Kitten, who have already promoted Avon products.
Avon advertises on TV in the US, but has not yet undertaken a TV campaign in the UK. The cosmetics company currently does not have an advertising agency in the UK, although it retains Carat as its media agency.
In the UK, Avon has a 160,000-strong sales force.
