So, this is the Eternal Shimmer cream in action. All products are by Illamasqua.
Before: I have Succumb (powder) all over, Command (cream) applied with fingers over lid and into crease. Upper lid lined with Sophie medium pencil, Drama (powder) smudged over that. Truth (powder) blended over lid and into crease.
And this is the after: Eternal smudged onto lid with a fingertip. You'll see it blends and just messes up the powder products underneath it a bit, as well as adding the slight seafoam shimmer.
Sorry the pictures are not great, but hopefully it shows what this product does.
