If you're looking for high-quality, innovative beauty products in a place where you can also pick the brains of a highly-knowledgeable staff, you're in the right place at BlueMercury. And sure, you could put your gift card toward one of their spa services, but these buys (including an ultra-wearable lip lacquer, a glitzy trio of nail polishes and a rejuvenating skin care set) are totally worth it too.
