To use I-Glide as an eyeliner, close your eyes, apply on the upper lash line, open your eyes, and stare in wonder. Not recommended for use on the waterline. To use I-Glide as your go-to eyeshadow, apply across the lid and blend with your fingertips or let our Smokin Eye Smudger Brush do all the work. Pro Tip: When applying I-glide eye pencil as a liner, try not to pull the skin on the side of your face. If things get a little messy, clean up your line with a q tip or a soaked cotton pad.
