I'd be honest. I have these tiny hairs on my upper lip area and every single time I take a picture for a lip swatch, they really show up! Hence, my full face picture instead of a close-up. (Now you know the reason) I've seen Asian bloggers and vloggers use this "thing" so I gave in.
I got this at Watsons for only 89.00php. All you have to do is form this into an upside-down "U" and twist the pink handles with your fingers to remove unwanted hair. Easy right? Kind of like threading, I guess. (I've never tried threading though)
