Three reasons you’ll love this poly gel
From the first bead to the final cure, everything works with you, not against you.
Quick-build flash cure
Apply, flash cure in just 60 seconds under any UV/LED lamp, then move right to the next nail. No waiting, no smudging — pro-level rhythm at your own kitchen table.
12 curated, salon-worthy shades
From soft Pure White to statement Magenta Fuchsia, each color delivers full coverage saturation. Mix and match — the only limit is your mood.
No harsh chemicals, ever
Free of MMA, toluene, and other nasties that weaken your nail bed. So your extensions stay strong and your natural nails stay healthy underneath.
What nail lovers are saying
Reviews from verified buyers who put the gel to the test.
Finally a gel that doesn’t make my natural nails feel flimsy. The shine lasts forever.
I saved over $200 in salon costs in two months. The hot pink is ridiculously vibrant.
Easy to work with, but I wish the tube was a little bigger. Still, a steal for the quality.
I’m a nail tech and use this on clients. It bonds better than some $30 brands. Impressed.
The pastel rainbow is subtle and gorgeous. Only tip: make sure your lamp is strong enough.
No lifting after 3 weeks! Usually I get lifting in a week. The flexibility is on point.
Perfect for beginners. The thick consistency doesn’t run, so I could build the apex without stress.
Good coverage but the gold tube is a little hard to squeeze near the end. I’ll definitely repurchase.
I’ve tried four poly gels and this one cures the hardest with zero tacky layer. Game changer.
3 minutes to begin your set
Your first extension set, step by step.
Prep your nails
Push back cuticles, buff the shine off the nail plate, and wipe with alcohol. The gel needs a clean, oil-free surface.
Apply a base coat
Thin layer of base gel, then cure for 60 seconds under your lamp. This is the glue that locks everything down.
Shape with the poly gel
Squeeze a bead of COSCELIA gel onto the nail and use a dual form or brush to sculpt your desired shape and length.
Cure and finish
Flash cure each nail for 60 seconds, then a final 120-second cure for the whole hand. Buff, top coat, and you’re done.
Proof that home can be salon-grade
