How does the lore describe parched Drukhari´s apperence?

As the title says how does the lore describe a Drukhari who has had his/her soul either almost or completely drained by Slaanesh as looking like?
I think i read somewhere that they look emaciated with luminous eyes.
But is there any other lore describing their appearance and if so how are they described?

Actually there is. A Harlequinn in the Path of the Dark Eldar trilogy can sense the nature of the souls of the eldar around him due to his psychic attunement. To him, the soul of Dark Eldar look very sinister and corrupt, even demon-like in some cases.

For the Harlequinn, it was an easy sport to spot the real Asdrubael Vect who likes to surround himself with body-doubles. Vect had an unparalleled malice and darkness to him that was not possible to mistake.

For this reason, I also like to paint my DE in a more undead fashion. Very pale with highlights of faint-blue.
