IPL: best for pale skin and light hair
Technically speaking, IPL (or intense pulsed light therapy) isn't a laser. But it's one of the most popular light-based hair removal types, so it would be rude not to mention it. While lasers send out a single beam of light, IPL sends out a whole spectrum. As it's less powerful than a laser, it can be less effective, which is why it's best for fair hair. It's also often a bit cheaper if you're on a budget.
