Safe, Easy and Cheap Face Exfoliation!

I used to exfoliate my face once a week but now I do it two or three times a week.  The reason?  I'm not worried about the chemicals I'm using in the exfoliation product I'm using!  

Once again, an Elder tipped me to some goodness.  I  noticed a small bowl on her bathroom counter and asked what she used it for.  After a lecture about being all up in her business ( was on the COUNTER!) and my ignoring her because she's always holding on to some good info she knows good and well I'd appreciate, she told me that she makes a paste of baking soda and water to scrub her face.  She told me that the humidity out here makes stuff stick to your face more and that pollen is a tricky fool.  (ROFL!)  Said that all you have to do is make a lil paste with baking soda and use that to scrub your face.

I couldn't get an exact measurement out of her because she just eyeballs it, but I find that a ratio of one part baking soda and three parts water is pretty good.  I've been using it because she's right...that pollen is a tricky fool.  LOL!  I've been doing it now for about three weeks and I don't have any irritation.  My skin feels and looks clean and smooth.  GO ME!  I could even use it on my skin in the shower too!

A box of baking soda costs little of nothing and it will last a long, long time.  She also told me that she uses it to brush her teeth sometimes too.  Says sometimes your teeth can feel a bit gritty and baking soda helps polish off the grit.  Makes sense.  

How often do you exfoliate your face?  What do you use?  Have you ever used baking soda?
