Match.com has apologised for a new ad campaign that suggests freckles are physical flaws after a flurry of complaints.
The dating website told ITV News it is in discussions "about removing these posters as soon as possible," as the Advertising Standards Authority confirmed it is investigating the campaign.
In the ads, an extreme close up of a red-haired woman's freckled nose and cheeks has the caption: "If you don't like your imperfections, someone else will."
They launched on Monday this week and appear on the London Underground.

The ASA confirmed that around a dozen people had contacted the watchdog to make a formal complaint and said it is "assessing" the ads.
