Nails that change colour as fast as your ideas.
Gentler ingredients. Just good vibes and great colour.

Clear indoors. Colour outdoors. Be Bold transforms from clear to soft magenta and deepens as the sunlight does its thing.
Wherever you go – school, park, or beach – your nails move with you. One polish. Endless confidence.

Sun out. Colour out. Confidence out.

PS: Colour-shift magic loves a refresh.
When the effect starts to fade, you can swipe on another coat and top coat to boost the effect, or refresh your whole mani if it's been a while.

⭐ Best results use BYBU Base + Colour + Top Coat together. Our formulas are designed to work as a trio.

Best Features

🌈 Sunlight Switch – Shade-shifting magic that transforms outdoors. Clear inside, soft magenta in UV (Sunshine).

💅 Smooth & Glossy Finish – Salon-style shine, easy at home fun.

🌱 Thoughtful Ingredients - Formulas include bio-sourced ingredients (like citrates from sugar) for a gentler approach.

🐰 Vegan & Cruelty-Free – Always kind. Always conscious.

☀️ Sun comes out. Confidence does too.

How to use

The polish that flips the script - watch it shift shades when the sun comes out.

Shake it Up – Give the bottle a good shake to blend the colour-transforming magic.

Paint Your Power – Brush on a thin coat of Be Bold polish. Let it dry.

One coat = cute.

Two coats = bold.

Three coats = bring full wow.

Let each layer dry before the next.

Seal the shine – Finish with Be Protected Top Coat to lock in colour, add gloss and help your mani last longer.

Pro Tip: The colour-change effect fades after a few changes. When that happens, just add another coat and topcoat to boost the effect again, or refresh your whole mani if it's been a while.

Our Formula & Ingredients

Because your nails deserve the best: fun, gentle and conscious of the planet!

We use photochromatic pigments, which are sythetic organic colour-changing molecules created in a lab. When UV light hits them, they change colour. Step back indoors and they change back to their original colour. It's like a tiny science moment happening right on their nails.

Safety Precautions

💅 Nail Polish Safety:

🌤 Store below 30 °C – Keep it cool and in the shade. Even magic polish needs a break from the sun when you’re not using it.

🔥 Fire Hazard – Nail polish is flammable, so no candles, flames, or hot stuff nearby.

👀 Avoid Contact with Eyes – If it accidentally gets in your eyes, rinse immediately with plenty of water.

🖐 For Nails Only (External Use Only) – Paint your nails, not your skin, bath, or pets (yep, we said it 🐶).

👅 Don’t Snack on It – It’s polish, not food. If someone does swallow it, get help from a doctor or Poison Centre fast.

🚸 Keep Away from Little Kids – Tiny humans might think it’s candy or paint. Keep it out of reach of young children.

🚑 If Swallowed, Seek Help – If someone does accidentally swallow the polish, get medical advice or call a Poison Centre immediately.

♻️ Recycle Right – Empty bottles can go in glass recycling. Leftover polish = follow local disposal rules.
