Cargo has already activated the feature on its lipstick and eyeshadow pages, which you can play with right now. While I notice a little bit of lag (and I do wish I can change the program's lip shape to fit mine), the virtual products can follow your face around if you don't move too fast or too close to the camera. Shopping platforms like CAKE can make buying makeup online loads easier, especially if there aren't a lot of beauty bloggers that share your skin tone. You might not be able to test a lipstick's longevity or texture, but even just having an idea of what a product might look like on you is better than buying blind.
