Looking for a good, long lasting, jet black liquid eyeliner pen? I may be able to help. :)
I will be comparing the three I use regularly: Stila Stay All Day Waterproof, Eyeko Skinny, and Dolly Wink. Each has their pros and cons and at the end of post I'll tell you the one I'd pick if I could only buy one.
Stila and Eyeko have a felt tip applicator. Stila's is very soft while Eyeko's very firm and stiff. Eyeko's is also much bigger in size. Stila glides on fairly smoothly with occasional skips. As for Eyeko, I have a hard time trying to get it to deposit the ink, let alone drawing a line.
Dolly Wink has a brush tip applicator that's neither too soft nor too stiff. It glides on so smoothly and flawlessly without skips or dragging/pulling. I get the best control out of Dolly Wink.
I usually use Dolly Wink to draw a line (and/or extend it out for a winged look) on my lash line then I use Stila to “tightline”. Yep, you read it right. I've been searching high and low for something that would stay on my upper waterline. I've tried pencil, gel liner, powder, nothing stays on like Stila. I just have to be very careful not to get the ink into the eye.
Stila has the best ink system hands down. It is so controlled and continuous that you don't have to worry about shaking the pen during application.
Dolly Wink has the wettest and shiniest formula. The ink usually comes out too much and may form a droplet near the tip. Must be very careful during application or the ink could get on your hand or worse, your made up face.
Eyeko… well, I'll be honest. I don't know why people are raving so much about this pen. The ink is VERY dry. As you can see in the swatches below. It doesn't matter how many times I shake, the ink just would not come out. To make a simple line, for Stila and Dolly Wink, I can easily achieve with just one stroke but for Eyeko, I have to press the pen so hard multiple times onto the skin to get the intensity I want. I purchased my first one, didn't like it, and returned it. Then this one was given as a gift and I couldn't possibly return so it's either I had bad luck twice or the pen isn't just all that it is claimed to be.
Dolly Wink and Stila can draw a very thin, crisp, intense black line which is perfect for creating wings or a subtle eyeliner look.
Eyeko, well, since the ink is so dry, I have a hard time creating anything. I usually end up with a thick eyeliner look because I just couldn't draw a precise line.
Stila and Dolly Wink will not budge! Through tears, rain, and sweats. The intense black stays on from morning to night (or to next morning!). The only thing to get it off is an eye makeup remover.
Eyeko, it fades on me at 5-6h. I'll still see the line when I get home but not with the intensity I apply in the morning.
Dolly Wink will give you the most bang for your buck if you go by the amount you get. However, you will be wasting the ink every time a droplet forms. I'd pick a Stila at this point.
As for Eyeko, the price is the same but you get half the product. Half the product that you couldn't get it to come out. I say, do yourself a favor, go to a store, and try it first.
In summary, the skin on the eyelids is very soft and sensitive and anything you apply on the area should be with ease. There should not be any tugging/pulling of the skin. I'd pick either Stila or Dolly Wink and stay clear from Eyeko.
