Last night a fabulous fashion-y crowd (Yigal Azrouel, Byrdie Bell, and the like) flocked to Saks Fifth Avenue to fete Francesco Clark of Clark's Botanicals and celebrate his new Cellular Lifting Serum, which is touted to increase collagen production and fend off wrinkles thanks to a special never-used-before ingredient: apple stem cells.

"My father and my sister are medical doctors and we're always researching new ingredients," explained Clark. "And by chance I read an article about the Uttwiler Spatlauber Apple in Switzerland that was nearly extinct. It was over-picked because this apple would never go bad because it has stem cells that are continuously repairing and regenerating and protecting the fruit." Combined with other substances like ginseng extract, the new miracle potion is supposed to reverse skin damage and even make your eyelashes longer in just three weeks.

A cult-favorite of fashion insiders -- fans include Gwyneth Paltrow, Claire Danes, Julianne Moore and Maggie Rizer (the face of the new product) -- the product line was actually born out of tragedy. Clark was an editor at Harper's Bazaar before a swimming accident in 2002 left him paralyzed and crippled his nervous system to the point where he couldn't sweat. This led to a search for the cure to his breakouts and, eventually, the formation of Clark's Botanicals. Clark is now an ambassador for the Christopher & Dana Reeve Foundation and 5% of the profits from the $340 bottle will go to curing paralysis.

"His lip balm is the best lip balm ever and I recommend it to all of my friends," said PR girl Bonnie Morrison. "It's got this amazing silky texture and it doesn't rub off." Fashion team Robert Tagliapietra and Jeffrey Costello are also big lip balm fans (they switched from Kiehl's). "Francesco came to our show about a year ago and we became fast friends," said Tagliapietra. "We're absolutely obsessed with his products now. They are surreal. There's no overwhelming scent and the packaging is beautiful, which I'm a sucker for." The guys have also been using Clark's moisturizer in their beards. "It makes it soft!" says Costello. Hmmm, might there be a beard balm collabo in the future? "It's not a bad idea," said Tagliapietra. "It might be in the works!"

We hope StyleList gets some of that commission.
