Glamouring
From Charmed
Glamouring is a magical method of changing one's appearance used by Witches, Warlocks, Whitelighters and Elders. It is similar to, but not synonomous with, Shapeshifting. The two differences between these powers is that firstly Glamouring casts an illusion around a being so the change is in appearance only, while shapeshifting physically transforms the being. Secondly, with shapeshifting one transforms into anything, even if that thing has not existed before, Glamouring is restricted to people or humanoid beings (as far as the show depicts). Glamouring can be activated by power, potion or spell. The first time glamouring is shown is when Warlock Anton glamours into the former lover of Piper's past life, who was Leo's past life. Also Leo Wyatt glamours into the demon Belthazor to train the sisters. In this type of glamouring the person manifests with bright blue orbs.
We see that Glamouring is used by Paige because she is half whitelighter. But we also see Phoebe and Piper glamour too, however they probably use the spell in the book of shadows "A Glamour To Change One's Appearance" mentioned in ("Morality Bites").
