My happy place, Barneys New York, is having its cosmetics promo next Thursday through Saturday (Sept. 18-20)—and the clouds shall part, trumpets will ring out, and chubby cheeked cherubs strumming lyres will flank the grand portal to NorthPark heaven. Or something like that. As a cosmetics junky, I live for this promo. Just spend $175 on cosmetics and/or frangrances (see how when I say it nonchalantly it seems like a drop in the bucket), and you’ll score a bountiful bag of goodies. It’s how I found the award-winning Deep Exfoliating Mask by Dr. Sebagh and the Sensai Silk Emulsion by Kanebo that I used under my wedding makeup. It’s like Christmas in a cosmetics bag. Go. Enjoy. Then tell me about all the life-changing products you found.
