GETTING STARTED

Your 3‑step flawless application

Perfect for absolute beginners.

  1. 01

    Prep your canvas

    File and buff the nail surface to remove shine. Push back cuticles gently, cleanse with alcohol, and ensure nails are completely dry.

  2. 02

    Apply & shape

    Squeeze a small bead of gel onto the center of the nail. Using the bottle’s brush or a separate tool, spread to the edges. The self‑leveling formula will smooth itself — no base paper needed.

  3. 03

    Cure & enjoy

    Place under an LED/UV lamp (or phototherapy device) for 60 seconds. Once hard, the color‑change magic is ready. Apply a top coat for extra longevity and shine.

I was skeptical about the temperature claim, but it really works. Cold water turns them pale, hot water bright pink.

Only giving 4 stars because I wish the color range included a true nude. Otherwise, amazing product.

HONEST FAQ

Your color-changing questions answered

How does the temperature-change technology work?
The gel contains micro-encapsulated pigments that shift their molecular structure at around 31°C. When your nail temperature is below that, they appear pale or sheer; above it, they deepen into vibrant shades. Heat from your body, sun, or even a warm drink triggers the transformation.
Do I need a UV lamp to cure this gel?
Phototherapy (LED/UV) is recommended for the fastest, most durable cure, but you can also use a standard LED lamp. The gel is phototherapy-compatible and will cure in about 60 seconds under a professional lamp.
Is this suitable for beginners?
Absolutely. The quick-building, self-leveling formula makes application forgiving. Even if your brush strokes aren't perfect, the gel smooths itself out before curing. No base paper needed.
How long does the color change last?
The color-change effect is permanent — it activates whenever the temperature crosses the threshold. The manicure itself lasts up to 30 days with proper prep and care.
Will the gel damage my natural nails?
No, when removed gently (soak off with acetone or use a nail drill), your natural nails remain intact. The no-base-paper formula adheres safely and doesn't lift.
Can I mix colors to create custom ombres?
Yes! Layer two different shades (e.g., Champagne Shimmer over Coral Ombre) to create unique gradient effects. The temperature reactivity of each layer adds an extra dimension.
Is it truly no-base-paper? What does that mean?
Traditional poly extension gels often require a base paper form to build the nail tip. Our advanced chemistry allows direct application onto the nail plate, saving time and reducing complexity. Just apply, cure, and go.
