Small fluid-filled blisters typically break out along the border where the outside edge of the lips meets the skin of the face.
The law of conservation of matter states that matter can be neither created nor destroyed during a chemical reaction. This means that all the atoms present before a reaction must be present after the reaction, and that the total mass of a system does not change as the result of a chemical reaction.he law of conservation of matter states that matter can be neither created nor destroyed during a chemical reaction.

Russian scientist Mikhail Lomonosov is the one who discovered the law of mass conservation in 1756 by experiments, and came to the conclusion that phlogiston theory is incorrect. Antoine Lavoisier 's discovery of the Law of Conservation of Mass led to many new findings in the 19th century.owever, matter is conserved to such an extent that matter conservation may be safely assumed in chemical reactions and all situations in which radioactivity and nuclear reactions are not involved. Even when matter is not conserved, the collection of mass and energy within the system are conserved.
