Insomnia

Insomnia opal multichrome eyeshadow on eyes, model Katie

A sheer wash of shimmer that stays quiet on its own, then wakes up completely the moment it meets a black base. It's the shade that made Nikkie Tutorials stop mid-tutorial, and the one Katy Perry reaches for on tour.

Insomnia opal multichrome eyeshadow look
On tour

Katy Perry's go-to for the stage.

Makeup artist Alexandra French bought ten pots of Insomnia to paint Katy head to toe in it for the tour — this is the exact pigment: a translucent shimmer that reads sheer under house lights and turns electric under stage lighting. Built to hold up through a two-hour set, camera flashes and all.

The technique that broke TikTok

Drag to see the shift.

Insomnia is sheer and cool-toned on bare skin. Sweep it over a black base and the same pigment turns electric, the exact move Nikkie Tutorials used to send this shade viral.

Pair it with Eclipse Shadow Potion Paint (our black base) for the full effect. See the bundle below.

The video that started it

Nikkie Tutorials wore it first.

This is the exact look from the video that sent Insomnia viral: black base underneath, Insomnia swept over the top. It's the technique this whole page is built around, and the reason the pigment sells out.

Karla's top tips

Four steps to the look.

Step 1, prep the lid with primer 01

Prep

Apply Fix Potion primer or a mixing medium to the lid. This is what the pigment grips onto.

Step 2, dispense the pigment 02

Dispense

Once the primer is tacky, use the built-in hole dispenser to tap pigment onto your brush or fingertip.

Step 3, apply and blend the pigment 03

Apply

Press and blend the pigment on. This is where the multichrome shift comes to life.

Step 4, layer the pigment for intensity 04

Layer

Build up for a more intense, multi-dimensional finish. Layering is where Insomnia gets its depth.

Why it works

Not just another shimmer.

Insomnia is part of the Opal Multichrome loose pigment eyeshadow range, a finely milled eyeshadow that can be used as a highlighter, eyeshadow or body shimmer. It feels like silk and blends like a dream.

Vegan & cruelty-free

Hand-made in the UK. No animal testing, no animal-derived ingredients, lab-created mica.

Before you buy

Common questions.

Smooth, lightweight and compact, closer to satin than powder, with a highly pigmented, long-lasting, flawless finish.

Yes. No animal-derived ingredients or by-products, and no animal testing on ingredients, formulations or finished products, though the range isn't officially certified.

Yes, always, especially for use near the eyes. Apply a small amount to your wrist, inner elbow or behind your ear and wait 24 hours before using it on your face.

0.7g of finely milled loose pigment. A little goes a long way, though the pot can look under-filled as the fine powder settles over time.

Shoot in low, natural light. The colour-shift is light-sensitive, and harsh direct light can wash the effect out.
