Like Deeba mentioned the eyebrows and the skin colour.
and Aishwarya has done a nosejob and something done to her cheeks.
But almost all celebs are into this business so...
Baaqi i wanto add,
i still have seen women who are much more beautiful than these in beautiful without makeup.
those eyebrows are a result of this accident she had. her skin colour has always been the same i.e. fair. as for nose job i truly believe she didnot go under any surgery for her nose. it doesnot look different to me whether its her miss world shoots, recent pics or ads before miss world.
this suggests that Ash hasn’t done anything major to her face. Maybe some botox but the features are exactly the same from 15 years ago unlike the other A listers.
Ash had a medium desi skintone until after she won Miss World, up until then she was the same sort of colour as everyone around her, even at at the Miss World contest she didn’t look pale..
