The Cold Laser used in this clinic will not harm the skin in any way.  the 635 nanometers is the same frequency as that of the mitochondria in each cell of our body.  Therefore heat is not admitted and the light is totally safe from harming the skin.  In fact we have one patient that have sever ulcers on both of her legs.  The ulcers were eating away her tissue.  She had marked caverns in both legs.  With using the cold laser her skin is healing, it is now pink, and is filling in the caverns.  The pain from the ulcers is gone.
