Ok, this little trick is for Rule #10...and I've been doing it for awhile and am very happy with the results.
I have sun spots (not freckles, larger) on my face and this has actually been lightening them ... I'd love to say removing them but no so sure that's true ...
3 tsp baking soda
1 tsp water
Mix the two in a small dish (I've been using a plastic 1 oz size cup) and apply to face in small circular motion. Rinse well and marvel at how clean your face looks and how smooth it feels.
NOTE: this makes MORE than enough for one washing so you can reduce the amounts by just remember, 3 parts baking soda to 1 part water (so 1 1/2 tsp baking soda and 1/2 tsp water, etc.). Leftovers can be used on your feet or just save for the next time by adding a little water again when ready to use. It will be more abrasive the 2nd time around so use caution!
Definitely an excellent DIY Beauty treatment for Rule #10.
