Got this in my November Ipsy bag, a brand I don't believe is available in Canada. It's advertised as an eyeshadow base, but it's coloured. This colour, Submissive is a darker gold colour. It seems to intensify the colour of any powder shadow, particularly when using a similar colour and adds a bit of glimmer too. But as an eyeshadow base it does not seem to stop creasing at all, and when mixed with UD lid primer I found by the end of an evening out that all my shadow had creased and the darker colours had worn off. Which does not usually happen when I wear the UD lid primer only. I'm not certain I'd say yes this is a must, perhaps if you do not have oily eyelids it would be more successful.

It is a very light bronze/gold metallic colour, it is excellent for hold powder eye shadows in place.
