ACIDS clotting

You can do an experiment: injecting into the fingers, squeeze out a drop of blood, a small drop of vinegar on blood will quickly clot. So the chemicals used after shaving are acidic. Usually the capillaries around the acid which accumulates in the body become blocked. So any organ or tissue near the acid buildup in the body are less blood supply, long-term damage may be caused by the accumulation of acid residue of them.
