A device for excising tissue and closing a wound that results from excision of the tissue includes structure defining an aperture into which tissue to be excised is exposed. The silicon parts include, for example, rings, electrodes and electrode assemblies. The pushing motion causes a rod to move the piston pump, which in turn raises water to the surface via piping into the trough where the animal drinks the water. Other environmental factors, such as oxidative stress, free radicals, environmental toxins such as ozone and cultural customs or habits such as tobacco smoking are other known probe accelerators in photo aging skin.
