About Plasma, the color of plasma produced by argon gas is orange. Nitrogen gas plasma emits blue light.

There are a lot of questions depending on the type of plasma, so I'll summarize them. The glass tube type that was widely used in skin clinics 20 years ago looks similar to plasma, but it generates ozone rather than plasma. Ozone is used for acne because it has a sterilizing effect, but overuse is harmful to the human body and is known to be a carcinogen. Currently, many new plasma equipment, including Plasono, have been released recently.

Another method of forming plasma is by generating argon gas using high frequency waves using nitrogen gas ACR method - Burns the skin and shrinks it. Used to remove wrinkles and elasticity spots. The color of plasma produced by argon gas is orange. Nitrogen gas plasma emits blue light. When plasma is created, it generates fine ozone. Prolonged exposure to ozone is not good so it can be used safely by blocking ozone through a glass tube.
