Myth: Lasers can make you look 20 years younger.
"There are many different types of lasers being marketed, and they all do different things," Kim says. "Some help with sun spots, some help with wrinkles. Some go deep and activate collagen. It's all marketed so much that people think it can make you a completely different person."
