Stick it on skin
Arm or leg — somewhere the sun actually hits. Peels on like a temporary tattoo, easy off at day’s end.
Sunscreen over everything
Lather your kid AND the patch. It now wears the exact same protection their skin does.
Watch the color
Clear = protected. Purple = UV is getting through — reapply. Check after swims: sunscreen wears off faster wet.
Easy to Apply and Remove
Peel, stick, done. Comes off just as easily when it's time for a new one — no residue, no fuss.

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.

SUNNYPATCH IS PERFECT IF…
My child often forgets to reapply sunscreen
The patch is the reminder: it starts clear and turns purple when UV is getting through — reapply now, not when someone’s already pink.
My child dislikes applying sunblock
The color-changing sticker turns application into a game instead of a chore — kids ‘win’ by keeping their patch clear.
I want to actually teach sun safety
UV is invisible; purple isn’t. The color change makes the lesson teach itself.
My child has sensitive skin
Keep the one sunscreen that works — SunnyPatch is compatible with all sunscreens and dermatologically tested across skin types and tones.
Beach days and outdoor activities
Water-resistant, compact, and a clear visual cue for reapplying after every swim.
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.
BUILT FOR OUTDOOR DAYS
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.

REAPPLY ALERTS, ON RECORD
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.
