I pride myself on being able to work with any texture, but damn....Helium has the texture of cornflakes!
I played around a bit and what really worked is:
Kool CCB
Flighty CCB (This looked the best out of all of them, IMO)
Mixing Medium
Haunting Fluidline
What was just OK as a base:
Eye Kohls (I tried it over MAC's Ms. Petunia Eye Kohl. I imagine that Gilded would look pretty hot)
Shadesticks (I tried it over Beigeing and also Pink Couture)
Primer Potion (IMO, this worked the worst out of them all)
I didn't even try paints as I am afraid they would be too dry to give the "grab" necessary to hold my cornflakes, I mean Helium.
Overall though, I am sprung on that colour. I've said it before and I will say it again: I love ANYTHING with a red pearl to it. It makes the colour pop. Think: Helium, Glamoursun LG, Elle LG.
I tried Helium with some clear LG and that is smokin. Tip: A little goes a long way. Don't believe me?? Give it a shot and you will see what I mean.
Is it even lip safe? I never check...my bad.
