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…
Finding a tolerated sunscreen took months
Then keep it. SunnyPatch changes nothing about your routine — it just reads whether that hard-won sunscreen is still working.
Reactive skin makes us cautious about stickers
Dermatologically tested, worn like a temporary tattoo, off at day's end.
Mineral sunscreens apply thick and weird
The patch doesn't care about formula type — cover it along with the skin and read the color.
Eczema-adjacent placement worries
Arm or leg, on a clear stretch of skin, somewhere they won't pick.
We burn through pediatrician questions
Bring the pack. Nothing absorbed, nothing ingested — an easy conversation.
Sensitive-skin families don't switch products lightly — the sunscreen that finally works is a family treasure. SunnyPatch is the rare add-on that asks you to change nothing: same sunscreen, same application ritual, plus one signal layer that says when the protection is fading. The page's line matters here: compatible with all types of sunscreen — 'pair it with your child's favourite sensitive skin-friendly sunblock.' Dermatologically tested, for exactly the families who ask.
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.

CAREFUL FAMILIES, ON RECORD
Will it irritate sensitive skin?
It's dermatologically tested across skin types and tones, and worn like a temporary tattoo. Try one patch on a small area first if you're cautious.
Does it work under mineral sunscreen?
It's compatible with all sunscreens — apply yours over the patch as usual.
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.
