I'm all for a skin care routine with items from the kitchen, I don't buy ANY beauty products anymore. I rinse my hair with apple cider vinegar, use talc as deodorant, and use bicarb. of soda to hand wash clothes. I say why bother forking out when you already have tons of bottles and packages lying in wait on a shelf? A lot of the traditional products we use for cooking; oils, honey, tea etc. have great uses in the bathroom too, and it's a lot of fun messing around. Just don't put cinnamon on your face. It will burn you. I made a soap out of cinnamon and charcoal once, and I will never do it again.
To infinity and beyond!
