Glass, rubber, and silk are known as what type of materials in esthetics?

Glass, rubber, and silk are categorized as insulators in esthetics and other fields involving electricity. Insulators are materials that do not conduct electricity well, meaning they restrict the flow of electric current. This property is crucial in the practice of esthetics, particularly when using electronic devices for skin treatments, where safety and effectiveness rely on proper insulation to prevent unintended electrical flow.

Conductors, on the other hand, would allow electricity to flow easily through them, which is not the case with glass, rubber, and silk. Electrolytes refer to substances that produce an electrically conducting solution when dissolved in a solvent, which is distinct from the materials in question. Solvents are substances that dissolve other substances, typically solids or gasses in liquids, and do not pertain to the conductive properties of the materials listed. Understanding the role of insulators aids estheticians in safely using electrical devices and ensuring the comfort and safety of their clients during skincare procedures.
