I have noticed that, in recent years, my once full eyebrows are thinning in some spots and nonexistent at the end of them. I have been poking around looking for something to define them a bit better without looking like a clown, and I think I have found it. It's called Diorshow Brow Styler (Ultra). I bit on the expensive side but I think it will last. It only comes in one shade and believe me it looks natural. I just fill in the blank spaces and elongate the brows and I feel like it does the trick.
In Dior's own words:
Diorshow Browstyler (Ultra) - $29.00
Expert precision for a tailor-made result. The Diorshow Brow Styler redefines, reshapes and fills out the eyebrow, offering high-definition makeup with a graphic yet natural result. Its single shade, Universal Brown, works on all skin tones. It features a retractable tip on one side for an ultra-precise line and a brush on the other side for easy blending.
