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.

Dermatologically tested across skin types and tones. Compatible with all sunscreens. Safe for all ages — the page says babies to Great Uncle Bob.
S’s review is a complete field test: behind the car’s UV glass, the patch stayed clear. The second the kids stepped into the sun — purple. Sunblock on: clear again. Beach, ocean, in and out of the water: purple, “signaling it was time for more sunblock. In a minute, the patch was clear once more. SunnyPatch is incredibly effective at alerting us when to reapply sunscreen!” One sticker, reading out the thing no parent can see.

🗒️
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.

Any brand, any SPF, sensitive-skin formulas included. Apply it right over the patch.

07 / QUESTIONS
Does it really work?
Yes — it’s designed to monitor sun protection through outdoor playtime. Its color change tells you when to reapply, and it’s compatible with all sunscreens.
How many do you need?
One patch per child, placed on skin that gets sunlight — arm or leg.
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.
