Look out for free Kiehl's Moisturiser samples being advertised on Facebook. To make sure you see them, follow their page, like some of their posts and comment on a few. Then exit the app, go back in and hopefully you'll see an advert pop up. If you do, just give your name, address and email to apply. Let me know if it works for you! If it doesn't appear, adjust your Facebook preferences or keep interacting with their content. You might have to wait a bit though.
