Re: I NEED a good eyeliner... that.
Do you like liquid eyeliner? I use a felt pen liquid eyeliner on my upper lids and love how it looks. You can apply it very thin and more natural looking, or thicker and more dramatic. I was surprised to find a very inexpensive brand for only a few dollars, Jordana. Ever since I tried it, I have continued to repurchase it. On my lower lash line, I have a bit more trouble. I like applying eyeliner to my waterlines, but I know what you mean about many kinds irritating the eye. I typically go for a soft pencil or twist-up eyeliner, or even a kohl-type eyeliner for this. I like the Rimmel brand for this, but I've tried a few that I like.
PS - The brand that burns my eyes the most is Urban Decay. They have great colors, but I stay away from their eyeliners now. I've also heard that Milani is a little irritating for sensitive eyes too.
