I tend to keep my makeup routine very simple. I have really sensitive skin so I don't pile on products. For every day I stick to a little powder, a bit of dark eye shadow smudged at the lash line as a soft, smoky eye liner, and my Dior Skinflash Radiance Booster Pen.
The Skinflash Radiance Booster Pen is probably the best and most important makeup product I own. The lightweight concealer clicks up onto a brush that helps you apply and blend the product. I use it mostly under my eyes, but it works on other blemishes too. It covers my dark circles without looking like I piled on a bunch of makeup. It wears all day and stands up to my constant eye rubbing (a habit I have on bad allergy days). It doesn't even settle into creases.
At $37 for .05 ounces, it might seem like a pricey buy. However, it wears better than any product I've ever tried. Also, the easy, built-in applicator minimizes waste so I don't need to purchase a new tube very often. (I don't wear make up everyday so the time between purchases varies based on how frequently I've been using it).
Lightweight, long-wear, full coverage, brightening, easy to apply, easy to use and simply amazing. I can't say enough good about this product.
