Fresh Again® deodorant sprays convert gaseous odor molecules into a solid. No gas = no odor! This process is much more complicated than the desensitizing, physical masking or digesting action of other deodorants. The result of this gas-to-solid conversion is also more desirable ~ no offensive odor whatsoever ~ instantly! Application of Fresh Again eliminates the production of more odor-causing molecules by inhibiting bacterial enzymes.
