Not Just a New Body - A Better Body
You've surely noticed the green skin tone of your new body. This isn't merely cosmetic. Your new skin (KloraDerm) incorporates chlorophyll to provide your body with an extra source of energy and to optimize your body's use of both oxygen and carbon dioxide. The result: You'll feel fresher, longer - and better able to perform you duties as a CDF serviceperson!
