Indeed in Miss Moss's first fashion shoots back in the early 1990s, she had quite a wide flat nose.
Photographed in 1998, the model still had a rather wide nose.
However five years later in 2003, its shape appeared to be a little narrower.
A year ago, pictured in New York, the central column of the nose still looked to be well-proportioned.
Most recently, Miss Moss, 32, went to a masquerade ball in London this week, and hid her face beneath a mask altogether.
However, when she was photographed at Heathrow yesterday, her nose looked to have much more marked indents on either side.
One leading plastic surgeon named Alex Karidis of the St John and St Elizabeth Hospital in North London argued surgery or drug abuse could have been to blame.
"The nose certainly seems to be retracted. Past drug abuse is certainly a possibility - but then so is surgery in the form of a tweak or adjustment."
