Use the luminizer pen along your cheekbones or anywhere you’d like to add highlight and radiance to your skin. You might notice that the packaging of this reminds you a little of the YSL Touche Eclat which is also a highlighter, but can be used underneath the eyes. Due to the Dior Flash Luminzer consistency, it has a bit of sparkle/sheen to it, so you probably won’t want that underneath your eyes to cover up circles. It will only enhance them.
