Generally speaking, the states of matter are divided into three types: solid, liquid, and gas. Plasma is called the "fourth state of matter". If energy is applied to a solid, it becomes a liquid, then a gas, and again, if high energy is applied to the gas state, the electrons in the atoms separate and it becomes a "plasma" state. Plasma, a substance that occupies 99.99% of the universe but is still unfamiliar, is used in many fields such as environment, fashion, agri-food, beauty, and health, and is a fascinating substance.
Cold plasma has a temperature of 35-40 degrees Celsius and temporarily "destroys" the lamellar structure in the epidermal barrier. As a result, it makes this structure looser and more relaxed for 10-12 hours, during which time the skin is more easily permeable to hydrophilic substances. Afterwards, the epidermal barrier restores its tight structure. In the event that the epidermal barrier is broken for some reason, cold plasma can repair it. The destruction of the lamellar structure also produces a disinfection process, destroying bacteria and fungi, inflammatory cells, and damaged cells. It also increases the epidermal permeability of the skin, thereby increasing the absorption rate of cosmetics by 84%.
