If you use an eyeliner pencil, sharpen it before every use. A sharp eyeliner will draw the line exactly where you need it to be and you will avoid thick lines and smudges from trying to remove it and apply it anew. On the other hand, not to be obliged to carry a sharpener with you all the time, you can replace the eyeliner pencil with liquid eyeliner pen that will give you the precision you seek. With its pointed tip, you can create any look you like, sleek or dramatic. source Neveya Cosmetics Co Pty Ltd Blog
