1. Maybelline Color Tattoo Metal eyeshadow in Barely Branded - As this has a metallic base I use this with eyeshadows that have some shimmer to them.
2. Models Prefer Shadow Pencil in Down To Earth - I mainly use these under taupe/brown colours to take them from boring to multi-dimensional.
3. NYX Jumbo Pencil in Milk - I tend to use this with matte shades that need help to show up on the lid although it looks great with shimmery colours too.
I don't use them with every eyeshadow, only ones that need a little bit of help to pop. Here are 3 eyeshadows that I think need that little bit of help, and how they look with and without "helpers". The eyeshadows are Rimmel Tribute, Maybelline Eyestudio in Navy Narcissist and Maybelline Eyestudio in Clover Couture. For the swatches below I used the darker shades of the Maybelline Eyestudios.
What do you think? Big difference huh? Do you use bases underneath your eyeshadows?
