Transform short nails into long, perfectly sculpted, glittering works of art — no salon appointment needed.
From boring bare nails to dazzling salon art
A 3-chapter journey from expensive appointments and limited options to the instant creative freedom of at‑home gel extensions.
Stuck in the salon cycle
Hours spent, hundreds of dollars, and still you wonder if the colour will turn out right. Between appointments, your nails look unfinished — until the next booking.
The glitter revolution
COS Coscelia Poly Extension Gel changed everything. A quick-building UV formula that slips on in minutes, cures under a lamp, and dries into a brilliant, crystal-clear glitter finish — no drill, no mess.
Your new nail ritual
Now it’s Friday night, and you’re already wearing next week’s manicure — a different shade on every finger if you like. Your nails are strong, stunning, and yours, without a single appointment on the calendar.
What makes the glitter genius
Three reasons this gel stands out from the rest — and why your nails will never look the same.
Quick‑building formula
Thick viscosity glides on smoothly and levels itself — no ridges. Cures in 1–2 minutes under a UV/LED lamp, giving you flawless extensions every time.
Salon‑worthy glitter
From turquoise sparkle to dusty rose, the ultra-fine glitter suspension delivers a head‑turning, crystal‑like shine that stays glossy and chip‑free for weeks.
Foolproof application
Squeeze tube with precision tip dispenses exactly the right amount. Use with dual forms or sculpt directly — included instructions guide you step by step, even for first‑timers.
How to apply your gel extensions

I was intimidated but the gel is so easy to work with. Cured perfectly in my cheap UV lamp.
Only downside: you definitely need a lamp. But once you have one it’s a game changer.
My nails look like I just stepped out of a magazine. I’m obsessed!

The dusty rose is my go-to. It's been 2 weeks and not a single chip!
Love the holographic silver shade! It’s better than the salon dip powder I used to pay $60 for every month.
Great product, just wish there were even more glitter options.
