WHAT’S ACTUALLY ON THEIR ARM
NO OILS. NO INGREDIENT LIST. ONE COLOR-CHANGING LAYER.
SunnyPatch is a photochromic sticker: a material layer that reacts to UV light. Clear when your sunscreen is doing its job, purple when UV is getting through.
It goes on skin like a temporary tattoo, wears the same sunscreen your child does, and reads out the one thing you can’t see: whether that sunscreen is still working. Nothing absorbed, nothing ingested — peel it off at the end of the day.

THE MOST USEFUL LINE IN S'S REVIEW ISN'T ABOUT THE BEACH
It's the car: “When out of the sun or behind UV glass, like in a car, the patch turns clear. As soon as they stepped into the sun, it turned purple.” Which means this isn't a beach toy — it's a UV meter for the ordinary Tuesday where most accidental sun happens: the walk from the far car park, the wait outside school, the 'quick' playground stop that becomes an hour. The patch doesn't distinguish holidays from errands. UV is UV.

WHY PARENTS KEEP A PACK IN THE BEACH BAG
🗒️
The color is the interface
No app, no battery, no charger. UV shows up as purple, on the patch, right where you’re already looking.
⏱️
Water-resistant
Stays on through pool and ocean. Check it after swims — sunscreen wears off faster when wet.
🌿
Works with your sunscreen
Any brand, any SPF, sensitive-skin formulas included. Apply it right over the patch.

Why is it clear in the car?
Car glass blocks most UV. The patch reads what actually reaches the skin — clear inside, purple outside is the system working.
Is a short errand worth a patch?
N's car-park burn says yes. One patch covers the whole outing, however many stops.
Is it water resistant?
Yes. It stays effective during water activities — but reapply sunscreen and check the patch after swimming or sweating, since sunscreen wears off faster.
How long does it last when worn?
As long as your child is out in the sun. Reapply sunblock whenever it turns purple and carry on.
Is it safe?
Non-invasive and worn like a temporary tattoo. Dermatologically tested; the page rates it safe for all ages, babies included.
Why does it stay clear in the car?
Car glass blocks most UV, so the patch stays clear — that’s it working, not failing. Step outside and watch it change.
How long will shipping take?
Orders dispatch same day; usually 3–5 days to the USA, Canada, Australia and Europe.
Do you offer discounts?
Multi-packs are the main way — see the pack picker below. We also run regular sales.
What if it doesn’t work for us?
30-day money-back guarantee. One beach day is usually all the test you need.
