This pencil is gorgeous gorgeous gorgeous! A slightly tealy green with golden sparkle that is brethtaking (to me as a big fan of green), these also stay put very well once they've set. You can smudge them when first applied but they do set fairly quickly. They are glittery but it's a nice fine glitter that I personally quite like, not as chunky as some cheaper glitter liners I've seen. One of the most beautiful and unbudgable eyeliners I've ever come across, for sure. I have no idea why MAC doesn't make some of their Pearlglides permanent, they seem to be very popular!

ABSOLUTELY GORGEOUS. does not stick on the water line but this color is A M A Z I N G .. The only reason I gave it 4 instead of a 5 rating is because of the mess when you take it off... the gold glitter gets everywhere around the eye area no matter what makeup remover i use...

Undercurrent is very beautiful green with glitter.
I noticed that UD's covet is same color but covet don't have the glitter.
Covet is also beautiful however I love undercurrent than UD's covet.
because I only use undercurrent lower corner lush line. so I want to more showing!

This is the first time I have bought a back-up of any cosmetic item, ever. It is also my first Pearlglide liner. The colour is INSANELY gorgeous and this is so easy to use. I do my makeup on the train on the way to work (hour-long trip) so all my makeup has to be very portable and non-spillable i.e. no pigment powders :(

This is like "pigment in a stick" in that it gives me the same vibrant colour and sparkle as I get from pigment powder and a wet liner brush. It lasts all day and through the night as well :)

I was on the fence about buying this liner because I felt that Undercurrent was a little too close in color to Float on By, which was released with To the Beach, or somewhat similar to Humid. I WAS SOOO WRONG!!! Undercurrent is mostly green with a touch of blue and small gold sparkles. Float on By is more blue with a touch of green and has a shimmer instead of the sparkles. Humid is a dark green with a gold shimmer. Undercurrent, and all of the other pearlglide liners, are limited edition, they are SUPER SOFT, the LASTING POWER IS INSANE, and the colors are AMAZING!!! I picked them up in every color. I will repurchase these everytime they're released, even though they should be permanent!!!

*Note: DO NOT USE THESE DIRECTLY IN YOUR WATER LINE! GLITTER + SCRATCHES ON EYEBALL + DAMAGE TO EYEBALL= NOT GOOD!!!

I'm so happy I finally caved and bought this! I love pearglide liners and have so many different colours but for some reason never picked this up. After swatching it again at the counter...I had to have it! I'm wearing it right now as a thin line on my upper eye lid with carbon black voluminous mascara...looks soo gorgeous and gives my eyes that sexy pop of colour. I got a tip from the lady at Mac to use this as an eyeshadow or base...its creamy enough to blend! I think I'll be wearing this alot.

Absolutely gorgeous mermaidy-teal color! Glides on as smooth as silk, and stays put all day. What's not to like???

Words cannot describe how much I LOVE this eyeliner!!! I am a fluidline girl all the way, but this product is so easy to apply and the color absolutely stunning!!! If you use your hand lightly, you'll get a nice pale teal-green with a bit of glitter in it, but if you increase the pressure, you're going to get an INTENSE dark green/blue with gold glitter that looks FANTASTIC on anyone!!! I usually have a very sensitive water line, but this stays on and doesn't irritate me much at all--when I first apply, it bugs me for a few minutes and then I'm over it.

This color is so versatile it's almost overwhelming. A little bit in your lash line gives you just a hint of color so it's perfectly noticeable (with the benefit of it not irritating your waterline, if you are sensitive), or more on the lid for a dramatic cat eye for nighttime. The swatch on the mac website truly doesn't do this color justice--get to the counter and try it yourself!!!!

Well to be honest, because of the pictures I thought this pearlglide is something in between green and blue but its not. Its a glittery green I would say. Even though the pictures are misleading I like the way it looks and it combines fantastically with moonlight night pigment.

Undercurrent is a such a stuning shade! It's a teal-ish color with gold glitter that applies smoothly. Due to the smoothness is doesn't stay as long as regular kohls do on me but who am I to say this is a bad thing? I wore this a lot during the summer months and got a ton of compliments, although I think it clashes a bit with my green eyes.
I don't see myself running out of it soon but if I ever would I would repurchase it in a heart beat.
