Hi, I would like to buy an IPL hair removal device due to the constrictive price of professional treatments. I have done some research into devices and plan on buying a high-end on such as the Phillips Lumea or Braun SilkEffect. I am aware that these devices work well on light skin and dark hair. Although I have dark hair, my skin is not light, although it is not dark either. Please advise whether IPL machines will be effective on my skin tone.
