Want a totally customizable face serum -- without going through the hassle of getting a chemistry degree? Skin Inc. My Daily Dose Custom Blended Serum Kit, $90, allows you to play cosmetic chemist in your own bathroom.

Kieh's also has a great kit that pays homage to the company's early days as an apothecary. After a super thorough (free) consultation in a Kiehl's store to determine the blend that will make every day a good skin day, you'll be sent home with your own Kiehl's Apothecary Preparations, $95 -- a kit that includes a concentrated serum and customized vials based on the results of your consultation. Once you take it home, break open the vials and squeeze them into the concentrate bottle that has your name on it. How simple is that?
