They can. I had a friend studying make-up arts use me for a 'remedial model' once (humiliatin'!), when I was about forty five years old. By the time she was finished I had easily a half kilo of 'product' on my face and looked like a fourteen year old doll... as long as we stayed under studio lighting. The cold light of the public washroom revealed a pretty scary lookin' powdery visage - under those lights I more resembled a seventeenth century French courtesan...d'une age certaine(sp?).
