The problem

Skin cancer is the most common cancer in America.1

More people are diagnosed with skin cancer each year in the U.S. than all other cancers combined.1 Most of it starts with the sun.

Sunscreen works.
When it's on.

In a landmark randomized trial, regular daily use of SPF 15+ sunscreen, used as directed, cut melanoma risk by 50%.8 The hard part isn't the science. It's getting enough of it, everywhere, every time.

General sunscreen research. Not a Sunspi clinical result.

Missed spots

Sunscreen only works
where it lands.

Spraying and rubbing by hand leaves gaps. Thin coats. Bare backs. Burned ears. Every miss is skin left in the sun.

the one you actually wear.

We forget it. We skip it on cloudy days. We don't reapply. Sunspi makes it easy to get it right.

say they often forget to apply sunscreen.13

27%

know the recommended minimum amount: at least 2 tablespoons.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.14

What's washing off.

NOAA says some chemicals in sunscreen and personal-care products threaten coral reefs and other marine life — including oxybenzone and octinoxate. A 2022 National Academies review found that specific chemical UV filters can harm aquatic life, including corals.15

  • Accumulates in tissue
  • Can induce bleaching
  • Can damage DNA
  • Can deform young coral
  • Can kill

Effects on coral as listed by NOAA.15 This is an active area of research.

Places are taking a stand.

  1. 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.17

  2. 2020

    Palau banned the sale and import of "reef-toxic" sunscreens, including those with oxybenzone and octinoxate.18

  3. 2021

    Hawaii made it unlawful to sell sunscreen containing oxybenzone or octinoxate without a prescription. Still in force.16

Questions.

What is Sunspi?

A booth you step into that gives you a full-body, even coat of reef-safe sunscreen in seconds, for a few dollars. Every inch covered, not just what's easy to reach.

How long does it take?

Seconds. Step in, get covered, step out.

What sunscreen does Sunspi use?

Only reef-safe sunscreen. No oxybenzone and no octinoxate, the two ingredients banned from sale in Hawaii. We'll share full formulation details with the demo.

How much will it cost?

A few dollars per session. Final pricing comes closer to launch.

When and where can I try it?

The demo is coming soon. Join the waitlist and we'll let you know.

Do I still need to reapply?

Yes. Follow the sunscreen label. Dermatologists recommend reapplying about every two hours, and after swimming or sweating.9 With Sunspi, reapplying takes seconds.

Is Sunspi a medical treatment?

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.
