“Sunburned from just standing outside my car and chatting for a bit!” — N, Florida
“Cursed with sunburns after every beach trip, no matter how diligent”
The patch says it before the burn does: purple = reapply
“Safe for babies, kids, or even your Great Uncle Bob” — their page, verbatim
Water-resistant through swims and sweat
☀️ Purple means reapply — that simple

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…
You're the one who burns, not the kids
N's whole review is adult self-use: ultra-fair, diligent, still burning — because nobody can see sunscreen quit.
Beach trips end in aloe vera
“Cursed with sunburns after every beach trip” — until the patch started calling the reapplies.
You tan… until you don't
L tans well and still uses it on intense days. The patch doesn't care about your base tan.
Golf, runs, garden hours
Long, slow UV exposure is exactly what a color meter is for.
You'd never wear a UV wristband
Fair. This is a sticker under your sleeve line, not an accessory.
N's review, verbatim: “As a Florida native with ultra-fair skin, I seem to be cursed with sunburns after every beach trip, no matter how diligent I am with sunscreen. I've even been sunburned from just standing outside my car and chatting for a bit! SunnyPatch has been a game-changer, providing an excellent visual reminder that says, ‘Hey! Apply sunscreen before you sizzle!’” Diligence isn't the problem — visibility is. The patch makes the invisible part visible.
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.

ADULTS, ON RECORD
Isn't this a kids' product?
The page says all ages — 'babies, kids, or even your Great Uncle Bob.' Same patch, any arm.
I have a base tan — still useful?
UV doesn't respect tans (L's review says exactly this). The patch meters the exposure either way.
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.
