Cool-touch contact window

The cool-touch contact window is built around a thin sapphire slice, designed to help manage surface warmth and improve comfort during IPL use.

Cool-touch contact window

During IPL use, the lamp produces warmth at the surface. The sapphire cool-touch window draws this heat away more quickly, helping the skin feel smoother and more comfortable on contact.

During use, the sapphire surface cools to a low temperature (around 10°C), keeping the contact area comfortable.

  • The thin sapphire slice transfers warmth away from the contact area more quickly.
  • Less retained heat means a smoother, cooler feel between flashes.
