Melt Cosmetics Inmortal Gel Liner is a deep black with neutral undertones and a matte finish. It had a longer dry down time, so for those who want a more smudgeable product or something that has enough fluidity to work as both a gel eyeliner as well as a base product, this is definitely in that vein.
The texture was moderately emollient, gel-like (lighter-weight than a true cream), and applied evenly. It had opaque color coverage in a single stroke that stayed on well for 10 hours without fading or thinning on me.
Melt Cosmetics Cultura Gel Liner is a muted, light-medium orange with strong, yellow undertone and a matte finish. It was richly pigmented in a single, fluid stroke, which applied evenly across skin whether applied with an angled brush or a flat, synthetic brush (as one might to use it as a cream base).
The texture was smooth, lightly creamy but more emollient and a bit “airy” in a way–very true to a gel formula. It took slightly longer to dry down, but it didn’t seem prone to migrating or moving around as it did so. Once in place, the color wore well for 10 hours without fading or thinning.
Melt Cosmetics Fortuna Gel Liner is a deep, emerald green with cool undertones and a matte finish. It had nearly opaque pigmentation in a single, fluid stroke that had a longer dry down time, so it was more readily manipulated and smudged, but I did feel like there was some hang time where I was really waiting for it to mattify (it appears glossy initially).
The consistency was more fluid, more gel-like than a cream, and it did seem to have a fair amount slip so it was hard to get a really even application in a single but it built up well with a second layer. It stayed on well for over 10 hours without fading or thinning.
Melt Cosmetics Santos Gel Liner is a brighter, medium-dark blue with strong, cool undertones and a lightly sparkling, metallic finish. It had good color coverage in a single layer, which was best built up with a second layer.
It was harder to get a really crisp, even line of color as the formula was rather emollient and slid around readily–almost too fluid–but on the flip side, it would make a nice cream eyeshadow or base because of that slip (the larger swatch shows a more even application). Once it dried down, it lasted well for 10 hours without fading or thinning.
