Gloss brand/method for lips?

I was looking through a lot of different faceups and I was wondering, is there a specific brand of gloss or a method/mixture to glossing?

Here you go

I use liquitex gloss... There are several kinds, from heavy to light. I use the one in the middle. If I want it less glossy I mix it with water, and if you want it super glossy add another layer. Any acrylic gloss should do.

I use the x-22 gloss (like Volks sells). You can find it at most hobby/model shops. It's very glossy undiluted, you can mix it with water for a semigloss finish. Clean your brushes well after using it, it's brutal on natural fiber brushes.

Oh alrighty, guess it's as simple as that. Thanks!
