Urban Decay Retrograde 24/7 Razor Sharp Liquid Eyeliner ($22.00 for 0.07) is a blackened purple with lighter purple, pink, and blue shimmer. It had semi-opaque coverage in one stroke, which was buildable to opaque coverage if I applied a second layer after the first one had dried down. (Trying to improve coverage while it is drying just moves the product around and creates an uneven, streaky result!) Once dry, the eyeliner stayed in place for the ten hours I wore it for.

Urban Decay Galactic 24/7 Razor Sharp Liquid Eyeliner ($22.00 for 0.07) is a light-medium pink with warm, yellow undertones and a fine, metallic shimmer-sheen finish. The consistency was fairly watery, which resulted in needing to shake the tube for half of a minute in order to mix everything together well enough to get semi-opaque coverage. It felt a bit clingy after it dried down, but it didn’t budge over a ten hour period. MAC Feminine Edge (DC, $16.00) is darker (90% similar).

Urban Decay Street 24/7 Razor Sharp Liquid Eyeliner ($22.00 for 0.07) is a deep, blackened teal with a satin sheen. It was nicely pigmented with opaque coverage in a single stroke. The consistency was thin, but it wasn’t as watery as other shades, so it was easier to work with and had better color payoff. This shade lasted for ten hours on me.

Urban Decay Zodiac 24/7 Razor Sharp Liquid Eyeliner ($22.00 for 0.07) is a medium-dark greenish-brown; it had a strong, dark brown base with lighter emerald green, olive green, and gold shimmer. The texture of the eyeliner was watery and thin, which resulted in streakier, sheerer coverage. I would recommend waiting for the initial layer to dry down, and then applying a second layer for better opacity. The eyeliner lasted for ten hours, though.

FORMULA OVERVIEW | Urban Decay 24/7 Razor Sharp Liquid Eyeliner ($22.00 for 0.07 fl. oz.) is supposed to be a water-resistant, long-wearing, “intensely pigmented” liquid liner with an ultra-precise (thin) applicator. There are cream shades and metallic shades; the cream ones have a shiny finish (so none dry matte), while the metallic ones have a more pearly sheen. They require 20-30 seconds worth of shaking, or else you’ll end up with a more watery, sheerer consistency that is hard to work with. If shaken for long enough, everything mixes and most shades are semi-opaque to opaque and thin without feeling watered down, but it is a very wet, thin formula that takes 15-30 seconds to dry down (depends on the shade–metallics dried faster for me, on the whole). Once it dries down, it does seem to shrink slightly and I can feel it cling to my skin a bit. The applicator is thin and flexible enough to maneuver around the curve of the lid. Something that was somewhat frustrating is that the formula is so thin and wet that I do get some splattering when I open shades as well as when I apply (like a dot or two randomly on face).

These remove pretty easily with just water and a light rub, but they don’t come off just rubbing with a dry fingertip at all, so removing those spots requires real makeup remover or a dampened brush/cotton swab. During removal, the eyeliner flakes off in small chunks. If I just sprayed the eyeliner with water and lightly dab or blot (or even just let the water evaporate), they didn’t smudge, fade, or run. I didn’t have any issues with the wear of them–they all went for a full 10-hours before I removed.
