Rubber base for strength
Adds flexibility and extra strength to weak or brittle nails
Rubber Base
Colour is only half the secret. On soft or bendy nails the polish flexes until it chips — Rubber Base underneath is the difference between days and weeks of wear. Together with your Gel Polish Starter Kit it completes the strength setup: the kit already has everything else you need. Nothing more to buy.
How it fits your routine: simply swap it in as your base layer — apply after prep, cure, then colour and top coat as usual. Same technique, no extra steps to learn.
What to expect: noticeably stronger, flexible nails that keep their natural feel, with wear for up to three weeks. And on no-polish days the warm nude 07 As I Am is beautiful worn entirely on its own.
Products included
09 Au Naturel is the classic, natural nude — balanced, soft and timeless. Reinforcement with a di...

Gel tips for length
Add instant length with soft gel tips for a sleek, salon look
Gel Tips Add-on Kit
Skip the waiting game. Growing natural nails takes months — Gel Tips give you salon length in one evening. And together with your Gel Polish Starter Kit, this add-on completes the setup: the kit gives you the colour and the basics, this gives you the length. Nothing else to buy.
How it fits your routine: after prep, place the pre-cured tips with Tip Gel and lock them instantly with the SnapCure lamp — then apply colour and top coat exactly as you would on your own nails. The tips are pre-filed inside and have a placement guideline, so it’s easy to get right.
What to expect: ultra-thin, natural-feeling length that lasts 3–4 weeks. When your nails grow out, you simply infill instead of starting over. The box holds 360 tips across 15 sizes — enough for many full sets.
Products included

Builder gel for length + strength
Our strongest system for durable, beautiful nails
Builder Gel Extension Add-on Package
For the nails people ask about. Gel polish alone can’t build length or shape — Builder Gel can. Add this package and your starter kit becomes a full salon setup: Builder Gel 03 Our Song, tips, tip glue, tip cutter and the Oval Brush — combined with the lamp and base products already in your kit, you have everything you need. Nothing else to buy.
How it fits your routine: after prep, attach and trim the tips, build the nail with Builder Gel and cure — then finish with the colour and top coat from your kit.
What to expect: our strongest, most durable system. When your nails grow out, you simply refill about every three weeks instead of starting over — and it soaks off easily when you want a change.

Pairs perfectly with
If you are completely new to doing your nails at home, it can be difficult to figure out which products you need and how to use them. That's why we have made it our mission to make it easy and safe for you to get started.
Gel Polish gives a beautiful color and shine to the nails and lasts up to three weeks. It can best be described as a hybrid between a classic nail polish and a gel, which unlike classic nail polish needs to cure under UV light to dry. When applying Gel Polish, your nail gets a little extra strength from our special Hard Base Coat that is included.
The starter kit contains:
• SmartFold UV/LED lamp
• The Gel Guide*
• Hard Base Coat
• Top Coat No Wipe
• Gel Polish 252 Voice Note
• Cleaner+ 50ml
• Premium Nail File 100/180
• Premium Buffer 100/180
• Primer 21FREE+
• Lint-free wipes (200 pcs)
• Cuticle oil
• Cuticle pusher
• Cuticle clipper
* You'll also receive The Gel Guide – a thorough and beginner-friendly guide that makes it easy to get started with DIY nails.
It includes an introduction to our starter kits, basic nail theory, product overviews, and visual step-by-step guides that show you exactly how to create beautiful results at home.
The guide also explains how gel products work – so you'll understand both the technique and the science behind them.
Remember to purchase your optional Gel Polish colors if you want a specific color in addition to the transparent Hard Base Coat and Top Coat No Wipe.
Also remember to purchase a Gel polish removal kit if you're using gel polish without any strengthening layer underneath.
