i got rid of liver spots a long time ago with h202 and Colloidal Silver baths. of course it pays to make your own CS because a gallon is over 200 dollars and almost 300 with shipping.
but a couple of cups of CS and h2o2 in a hot bath will do wonders and feels wonderful. very relaxing and energizing at the same time. i used to put a quart of CS, some super concentrated homemade stuff, and a cup or two of h2o2 food grade 35% in the tub and soak away. it lightened my hair in the back, so i made sure to get my whole head under to keep the color even. i suppose the same principle could be applied with a spray bottle, but the rest of you skin and body will be jealous.
