If you want to give back but don't really know where to begin, why not start with your beauty regimen? Seriously. Making a difference is now as easy as dabbing on a serum. Let us explain: Effective immediately and until April 15, Kiehl’s has partnered up with DonorsChoose.org—an online charity that makes it easy for anyone to help students in need. How does it work? Public school teachers from every corner of America post classroom project requests on the site, allowing you to give any amount to the project that most inspires you. Amazing, right? So here's how you can make your beauty mark. All you have to do is purchase the limited-edition, jumbo-size 3.4 oz. Kiehl's Powerful-Strength Line-Reducing Concentrate, $100, kiehls.com—which helps reduce fine lines and wrinkles, and improve skin's texture, by the way! Then, once you've purchased the concentrate, look for the $50 DonorsChoose.org gift code found in the underside of each sleeve. Next, punch that code in here to choose a science education project to contribute to. Easy enough. Now, for the super cool news: Kiehl’s will be donating 100 percent of net profits up to $50,000 from the sales of each concentrate to the science education projects that you chose from local public schools or from anywhere in the country!
