Azazello

In the Old Testament apocryphal Book of Enoch 8:1-3, Azazel is the fallen angel who taught people to make weapons and jewelry:

1 And Azazel taught men to make swords, and knives, and shields, and breastplates, and made known to them the metals of the earth and the art of working them, and bracelets, and ornaments, and the use of antimony, and the beautifying of the eyelids, and all kinds of costly stones, and all 2 colouring tinctures. And there arose much godlessness, and they committed fornication, and they 3 were led astray, and became corrupt in all their ways.

Thanks to Azazel women learned the "sinful art" of painting their faces, so it is clear why he delivers the cream which has the effect of making Margarita young again.
