Two faces that appeared on my Instagram feed in recent months gave me pause. One belonged to John Travolta at Cannes. The other to Carla Bruni on a date night with her husband, former French President Nicolas Sarkozy. Both looked recognisably themselves, yet, they both also looked oddly unfamiliar. Their looks have provoked speculation about cosmetic enhancement, though never acknowledged by them. Bruni has previously denied having had work done.
In any case the feeling lasted only a second: a flicker of unease, as though I were looking at people who had become approximations of themselves.
