01 / THE INGREDIENTS
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.

Ziplock resealable bagSpares stay fresh all summer
Peel & stick on skinOn like a temporary tattoo
Dermatologically tested across skin types and tones. Compatible with all sunscreens. Safe for all ages — the page says babies to Great Uncle Bob.
“I JUST DON'T KNOW IF THIS PRODUCT IS REALLY NECESSARY”
That's Amber, on our own widget — kept, displayed, and now in our ad. Laura's is up there too: “Tbh I haven't tried it yet but seems like a brilliant straightforward idea.” Why lead with doubt? Because 71 auditable reviews with the three-star band visible beat a thousand-review wall you can't check. The believers are specific — S timed the color cycle on a California beach; N stopped burning at the car. The doubters are honest. You get both, then a 30-day guarantee.

🗒️
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.

07 / QUESTIONS
Why do you show lukewarm reviews?
Because you'd (rightly) distrust a page without them. The widget shows the full histogram — 71 reviews, every band.
What if it does nothing for us?
30-day money-back guarantee. One sunny weekend is all the experiment needs.
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.
