If you've been a very, very good girl, you might want to ask Santa to send you Prescriptives' Custom Blend Essentials kit ($115, a $165 value). Inside a metallic train case, you'll find two full-size brushes, a travel-sized bottle of Super Line Preventor Xtreme, and empty bottles of foundation and concealer. The gift recipient can go to one of Prescriptives' Custom Blend counters (find a location here), and she'll watch as the foundation and concealer are whipped up to her specifications right before her eyes.
I loved my Custom Blend experience because, well, custom anything makes me feel like a VIP. But it's a worthwhile splurge if you have a hard time finding the right shade of foundation; mine disappears perfectly into my skin, and it lasts forever. At $115, this kit is indeed a splurge — but it would also be a great gift to find under the tree, no?
