Unfortunately, mirrors don’t lie.

Especially the magnifying ones. So you sit there and pluck, pluck, pluck — until all that’s left is an overexcited (and malnourished) arch.

If you can’t wipe the look of surprise off your face, fill it in with Talika’s Eyebrow Extender, a genius contraption that will change your relationship with Mr. Tweezerman forever.

The pen-like brush is filled with clear gel and minuscule black fibers. Just twist the base, let the comb fill up, and brush on. (Think of it as a brow pencil or shadow.) Hands off for a few minutes while the gel sets, and when it dries you’ll find full, faux brows that won’t budge until you wash them off. (Cool, right?)

Since it comes only in black, it works best for darker complexions.

As for the fairest of them all, well, they can take comfort in the candor of their mirrors.
