Enjoy a traditional gel polish manicure with our 3STEP Colour Gel Polish! Achieve salon-quality like nails in the comfort of your own home.

1. Prep your nails: lightly buff nails and cleanse with 70%+ alcohol to remove oils and dusts. Wait for nails to dry completely. No primers, bonders or heavy sanding required.

2. Apply a thin coat of base gel polish. 3STEP is optimized for use with our Base-1 Gel Polish or Base Sculpting Gel. Cure for 30 seconds in LED lamp or 60 seconds in UV lamp. Note: base gel will always remain tacky even after curing.

3. Apply a thin coat of 3STEP Gel Polish and do not cap the free edge. For best gel colour application always shake well before use and paint in thin layers. 

4. Cure for 60 seconds in LED lamp or 120 seconds in UV lamp. Our 3STEP Gel Polish is optimized for use with our U-Light Pro 6. For all other lamps, we recommend to double the cure time.

5. Repeat steps 3 & 4 until coverage and desired opacity is reached.

6. Apply a thin coat of top gel polish. 3STEP is optimized for use with our No-Wipe Top Gel Polish or Top Sculpting GelCure for 60 seconds in LED lamp or 120 seconds in UV lamp.

Sooo in love

Absolutely LOVE this polish. It quickly became a go-to except never want to change it. I included a picture of warm fingers and cold for comparison. Love each end of the shade spectrum and all of them in between!

Love the colours!!!!!

This was one of the colours I kept going back to last summer! And probably again this summer. Definitely be ordering another bottle soon. :)

Fun fun fun!

This is such a fun colour and I love it for the summer! I really love the jelly finish and the name really suits the colour


Love the "I'm really a mermaid" collection! I have 4 of the shades from that collection and I'm really obsessed.

A great polish

This is a lovely shade, and I'm surprised by how well the colour shift occurs. When cold, its a dark grape.
When warm, mine doesn't shift to a magenta pink like you see in BSG's picture, but instead, a dusty mauvey pink. Its still a dramatic change, and it is beautiful. Natural nails feel strong, and product has does not easily chip. Fully opaque in 2 coats.
