Pat McGrath's 'porcelain doll' makeup from the John Galliano show has gone viral. The Internet has gone crazy with theories about how the makeup was made.

McGrath herself wrote herself in an Instagram entry in which the models were seen removing the product from their skin in a loop. The key is, as she herself confirms, to dilute the product in water, apply it with a sprayer and dry between coats, says McGrath. She says that she makes up to five applications and at the end shows the result, very similar to that of the Margiela show.
