The problem
More people in the U.S. are diagnosed with skin cancer each year than with all other cancers combined.1 Every one of them is a person who heard the word in an exam room and went home to tell someone they love.
9,500+
people in the U.S. are diagnosed with skin cancer. Every day.2
That's more than six every minute. Someone's mother. Someone's teammate. Someone who thought it was just a freckle.
8,510
Americans are expected to die of melanoma in 2026.3
About 23 people a day. Close to one every hour, all year long.
It almost never starts with anything dramatic. A burn across the shoulders after a long day on the water. A strip of back you couldn't reach. A sting on the backs of your legs you shrug off by dinner.
Then another summer. Another burn. On average, a person's risk of melanoma doubles after more than five sunburns.4 None of them felt like the one that mattered.
1 in 5
Americans will develop skin cancer by age 70.5
112,000
new invasive melanoma cases expected in the U.S. in 2026.3
+46.6%
rise in new invasive melanoma cases diagnosed each year, 2016–2026.1
Where it's found changes everything.
Catching it early saves lives. Never getting the burn is better still.
~86%
of melanomas were attributed to UV radiation from the sun in one UK study.7
In a landmark randomized trial, regular daily use of SPF 15+ sunscreen, used as directed, cut melanoma risk by 50%.8 The protection already exists. The problem is getting enough of it, everywhere, every time.
That's what Sunspi is for: an even coat of reef-safe sunscreen from the neck down, in seconds, for a few dollars.
The 50% figure is general sunscreen research, not a Sunspi clinical result. Sunspi is not a medical treatment.
Why sunscreen falls short
Nobody gets this wrong on purpose. Bottles, sprays and two hands just weren't built for the job. Here is what the research shows.
01
SPF numbers are measured at 2 mg of sunscreen per square centimeter of skin. For an adult body that's about 1 ounce, roughly a shot glass.9 In real life, people put on far less: about 0.39 to 1.0 mg/cm² under natural conditions.10
25–50%
of the recommended amount is all most people apply.9
02
Sunscreen only works where it lands. Hands miss the places they can't easily reach or see: the back, the shoulders, the backs of the legs, the feet.
31%
of target skin showed no sunscreen after a single cream application in a fluorescence study. The central back, legs and feet, especially the soles, were often missed.11
71.5%
of the back was covered when people applied sunscreen to it by hand. The middle back got the least.12
27%
of Americans know the recommended minimum amount: at least 2 tablespoons.13
0
Median coverage on the back of the neck and the ears in one study of hand application. Those are part of your own face-and-head step, so give them a second look.14
03 Rarely reapplied
We forget it. We skip it on cloudy days. And once it's on, most of us never put on more.
38%
of sunscreen users typically reapply every two hours.13
28%
tend not to reapply at all.13
53%
say they often forget to apply sunscreen.13
21%
use sunscreen regularly on cloudy days. 57% do overall.13
Only 12.3% of men and 29.0% of women said they always used sunscreen when outside on a sunny day for more than an hour.15
04
Wind carries the mist away, and a clear, fast-drying spray makes it hard to tell what you've covered. Dermatologists say to skip spraying on windy days, spray until skin glistens, then rub it in anyway.16
One report in the Journal of the American Academy of Dermatology described blotchy protection: skin inside the mist was spared while the skin around it burned.17
05
Greasy hands. Sand that sticks. Someone waiting at the water's edge while you wrestle with your back. When applying sunscreen is a chore, it gets rushed or skipped, and a rushed coat is a thin coat.
06
Used the way it's tested, sunscreen goes fast. A typical 6-ounce spray bottle holds just six applications.18
A 2011 analysis estimated that a family of four at the beach applying the recommended amount would spend a median of $178–$238 a week on sunscreen, at 2011 prices.19
07
Oxybenzone and octinoxate are still permitted in U.S. sunscreens. NOAA lists both among the chemical UV filters that can harm marine life, including corals.20
Hawaii has banned their sale without a prescription since January 1, 2021.21 Palau banned reef-toxic sunscreens from 2020.22 Key West passed a similar ordinance in 2019, but Florida preempted it, so it never took effect.23

Made for where you play
The ocean
Float face-down over a living reef and the world goes loud with color. Fish flicker through branching coral. Everything moves, eats, hides, grows.
A bleached reef is the same place gone white as bone. Quiet. Coral is alive, and when it bleaches, it is starving. Sunscreen is not the only thing hurting reefs. But it is something we carry into the water ourselves, every day, by choice.
What NOAA says some sunscreen chemicals can do to coral:20
Oxybenzone and octinoxate are among the chemicals NOAA lists as able to harm marine life. A 2022 National Academies review found that specific chemical UV filters can harm aquatic life, including corals. This is an active area of research.20
Every swim rinses some of what we're wearing into the sea. NOAA describes mineral sunscreen as a better option for the water, with fewer effects on aquatic organisms.20
2019
Key West passed an ordinance banning sales of sunscreens with oxybenzone or octinoxate. Florida then preempted local rules in 2020, so it never took effect.23
2020
Palau banned the sale and import of "reef-toxic" sunscreens, including those with oxybenzone and octinoxate.22
2021
Hawaii made it unlawful to sell sunscreen containing oxybenzone or octinoxate without a prescription. Still in force.21

Yes. Follow the sunscreen label. Dermatologists recommend reapplying about every two hours, and after swimming or sweating.9 With Sunspi, reapplying from the neck down takes seconds. Remember to reapply on your face and scalp too.
No. Sunspi applies sunscreen. It does not diagnose, treat or cure anything, and it's not a substitute for regular skin checks. The melanoma and sunscreen figures on this page come from general published research, not from studies of Sunspi.
