This Laser Hair Removal Video Is the Wildest Thing You'll See Today

If you crave a fuzz-free upper lip or yearn for a bikini line forever unblemished by ingrowns, laser hair removal might be for you. But before making such a permanent change to your look (and, not to mention, such a big financial commitment), you should know exactly how the procedure works.

YouTube users Physics Girl, Veritasium, and BeyondSlowMotion visited the Santa Monica location of LaserAway, a California laser hair removal chain endorsed by Kim Kardashian, to break down the concept. Veritasium, known as Derek Muller, bared his arm for the device as each zap of the infrared laser was filmed.

While the video does get pretty technical, it's highly informative for both first-time patients and those just interested in learning about the process. Did you know that your hairs (and their follicles) heat up to over 100 degrees Celsius when hit by the infrared light? This causes the water in each strand to vaporize, killing the germ cells that cause them to grow. Discover that and more fun facts when you watch now.
