Lesson 3 of 12

The light

Five kinds exist. Only one belongs anywhere near a salon chair.

What you will learn

  • Why blue LED and not the other four
  • What the light actually does to the gel
  • How to handle the lamp without breaking it

Blue LED

A cold light. It cannot burn soft tissue. The LEDs themselves get very hot, which is the useful part: the lamp raises the temperature of the gel slightly and that activates it.

The rest of this lesson

  • The four lamp types that do not belong near a salon chair, and why
  • How far the lamp sits from the mouth, and for how long
  • The one movement that breaks these lamps
