Summer 2025 is all about embracing the whimsical, ethereal allure of the ocean with the “Mermaidcore” aesthetic, especially when it comes to eye makeup. Move over muted tones; this season, we’re plunging into vibrant aquamarine blues, shimmering “wet-look” shadows, and playful pastel neons that evoke the magic of the deep sea.

 

If you’re ready to make a splash with your summer look, this guide will help you master the “Mermaidcore & Aquamarine Eyes” trend, along with product recommendations and essential tips for long-lasting wear, even in the humidity.

 

 

 

 

What is “Mermaidcore” Eye Makeup?

 

“Mermaidcore” eye makeup is inspired by the iridescent beauty of mythical sirens and the shimmering depths of the ocean. It’s characterized by:

 

Vibrant blues & greens: Think shades of aquamarine, cerulean, cobalt, teal, seafoam green, and shimmering turquoise.

 

Iridescent & shimmering finishes: Pearlescent, duochrome, and glittery textures that catch the light like scales or water.

 

“Wet-look” effect: Glossy lids that appear perpetually dewy and fresh, mimicking water droplets.

 

Playful pastels & neons: Unexpected pops of electric blue, lime green, or lavender to add a fantastical element.

 

Soft, blended edges: Often less about harsh lines and more about diffused, watery washes of color.

 

This trend is perfect for summer, bringing a refreshing, cool-toned vibrancy that stands out from the usual warm-weather palettes.

 

 

 

 

Mastering the “Mermaidcore & Aquamarine Eyes” Trend

 

Ready to transform your eyes into oceanic masterpieces? Here’s how:

 

1. The Shimmering “Wet-Look” Shadow

 

This is the cornerstone of Mermaidcore. The goal is to create a luminous, dewy finish that looks perpetually hydrated.

 

Product recommendations:

 

Cream or liquid eyeshadows: These are easiest for achieving a seamless, glossy look without creasing.

 

Kaja Eye Bento Bouncy Eyeshadow Trio in Sparking Rose (for an iridescent shimmer that can look wet).

 

 

 

Glossier Lidstar in Cub (a shimmering rose gold that adds a subtle wet sheen).

 

Stila Glitter & Glow Liquid Eye Shadow in Diamond Dust (for an intense, multi-dimensional wet glitter).

 

 

High-Shine Glosses (applied sparingly over shadow):

 

Danessa Myricks Beauty Colorfix Eye, Cheek & Lip Cream Pigment in Clear (for a true glossy effect over any shadow).

 

MAC Lipglass Clear (a classic for a high-shine, non-sticky finish on lids).

 

e.l.f. Cosmetics Liquid Glitter Eyeshadow (various shades for a high-impact shimmer).

 

How-to:

 

Apply a small amount of cream or liquid shadow with your fingertip or a flat brush. For an extra wet look, dab a tiny bit of clear gloss over the center of your lid after your shadow has set, being careful not to use too much to avoid creasing.

 

 

2. Vibrant Aquamarine & Cobalt Hues

 

These cool-toned blues are central to the mermaid aesthetic.

 

Product recommendations:

 

Eyeshadow palettes:

 

Huda Beauty Mercury Retrograde Palette (features stunning blues and greens).

Juvia’s Place The Zulu Eyeshadow Palette (for a vibrant electric blue).

 

Individual Powder Shadows:

 

MAC Eyeshadow in Atlantic Blue (a vibrant cobalt).

 

 

 

NARS Single Eyeshadow in Douro (a shimmering aquamarine).

 

Cream Eyeshadow Sticks:

 

Laura Mercier Caviar Stick Eye Colour in Intense Amethyst (a deep, rich purple-blue for smoky looks) or Cobalt (a vibrant blue).

 

Milk Makeup Infinity Longwear Eyeliner in Limitless (a deep teal).

 

How-to:

 

Apply a wash of color across the lid, blending the edges softly. You can use one shade for a monochromatic look or blend multiple shades for a more complex, oceanic gradient.

 

 

3. Playful Pastel Neons

 

Inject a whimsical, fantastical element with unexpected pops of pastel neons.

 

Product recommendations:

 

Eyeliner pencils/liquids:

 

NYX Professional Makeup Epic Wear Waterproof Eye & Body Liquid Liner (available in electric blue, lime green, and fuchsia).

 

 

 

Urban Decay 24/7 Glide-On Eye Pencil (look for shades like Electric, Psychedelic Sister, or Deep End).

Liquid or Cream Eyeshadows:

 

Suva Beauty Hydra Liner / FX in Acid Trip (a vibrant lime green) or Space Panda (electric blue).

 

Lemonhead.LA Spacepaste in Electric Daze (for iridescent pastel neon glitter).

 

How-to:

 

Use these as a pop of liner, in the inner corner, or as a vibrant accent over a more subdued base.

 

 

 

Tips for Long-Lasting Wear in Humidity

 

Summer humidity can be makeup’s worst enemy, but with the right prep, your Mermaidcore look will stay flawless.

 

Prime, prime, prime: An eyeshadow primer is non-negotiable. It creates a smooth base, enhances color vibrancy, and significantly improves longevity.

 

Product: Urban Decay Eyeshadow Primer Potion, NARS Smudge Proof Eyeshadow Base, or Milani Eyeshadow Primer.

 

 

 

Layer formulas: Start with a cream or crayon base, then layer a powder shadow of a similar shade on top. This “locks” the color in place.

 

Waterproof formulas: Opt for waterproof eyeliners and mascaras.

 

Product: Maybelline Lash Sensational Sky High Waterproof Mascara, Lancôme Monsieur Big Waterproof Mascara, or Stila Stay All Day Waterproof Liquid Eye Liner.

 

 

Setting spray: Finish your entire makeup look with a setting spray, focusing on the eye area.

 

Product: Urban Decay All Nighter Setting Spray, Morphe Continuous Setting Mist, or Charlotte Tilbury Airbrush Flawless Setting Spray.

 

Less is more with gloss: While a wet look is desired, too much gloss can lead to creasing. Apply very sparingly and only in the center of the lid. If you have oily eyelids, skip the gloss entirely or use a shimmering cream shadow for a similar effect.
