We love us a good anti-aging trick, and it looks like the clever chemists at Rodial have delivered yet again.

The Brit brand's Glamtox Serum has been a skin-tightening and lifting favorite of the well-heeled crowd, and now Rodial is launching an eye pen version exclusively at Nordstrom stores this October.

(By the way, these are the same folks who brought you snake serum. Check it out on their Facebook page.)

The skin-brightening fluid fills wrinkles with hyaluronic acid, and cools, de-puffs and firms with lotus extract in a universal highlighting shade. Click to release product, and then stroke the sleek silver pen over dark eye circles, the sides of the nose, or anywhere else that needs a shot of light. Outlining the contours of the lips will also make lip color pop.

True, this handy little pen has all the makings of a can't-live-without it must-have, and StyleList wants to get you in on the action -- for free.
