Two everyday  items that work as super affordable skin exfoliants are  baking soda and sugar. The really nice thing about both(besides price) is that they can be bought just about anywhere.

That $16.00 sugar scrub that you bought at your local apothecary is 80% sugar which costs you pennies per lb.If you do a few experiments with oils you have in your pantry(coconut oil etc) you can find a combo that is perfect for your skin. Also you can adjust the sugar and or baking soda content to make best exfoliant level for your application depending if you want to take off a lot of surface skin or just want a  a gentle scrub.|| One girls experience.
