Final answer:

The three main electric modalities in cosmetology are Galvanic Current, High Frequency, and Ultraviolet Light, each with unique applications such as skin treatment and sterilization of equipment.

Step-by-step explanation:

The three main electric modalities used in cosmetology include:

  • Galvanic Current: This is a direct current modality used most frequently for facial treatments. The galvanic machine causes a chemical reaction when it interacts with a saline solution on the skin's surface, thereby enhancing the absorption of products into the skin. It includes processes like iontophoresis and desincrustation. Iontophoresis infuses water-soluble substances into the skin, and desincrustation helps soften and emulsify sebum and debris for easier extraction.
  • High Frequency: High frequency uses alternating current to generate heat and produce a mild to moderate thermal effect. It is beneficial for treating and preventing acne, shrinking enlarged pores, reducing the appearance of fine lines and wrinkles, and promoting hair growth by stimulating circulation in the scalp.
  • Ultraviolet Light: Low-intensity ultraviolet light is utilized in cosmetology mainly for its germicidal properties. It is often used to sterilize trimming implements and has a higher frequency compared to other electromagnetic waves, depositing energy differently into materials it interacts with.
