Maui Sunscreen Rules: Your Essential Guide for 2026

If you’re planning a sun-soaked getaway to Maui or the neighboring islands in Maui County, understanding the Maui sunscreen rules isn’t just smart — it’s required. Maui County and the State of Hawaiʻi have some of the most progressive sunscreen laws in the world designed to protect fragile coral reefs and marine ecosystems while keeping your skin safe.

What Are the Maui Sunscreen Rules?

As of October 1, 2022, Maui County Ordinance No. 5306 prohibits the sale, distribution, and use of non-mineral sunscreen products unless you have a prescription from a licensed healthcare provider. That means you cannot legally use chemical sunscreens on beaches, in the ocean, or anywhere on Maui, Moloka‘i, or Lāna‘i unless they are mineral based.

In addition, Hawaiʻi state law already banned sunscreens containing oxybenzone and octinoxate, two chemical UV filters shown to harm coral reef development and health.

Put simply:

Allowed: Mineral sunscreens with zinc oxide and/or titanium dioxide as the only active ingredients.

Not allowed: Chemical sunscreens without a prescription — this includes many products labeled “reef safe” that still contain chemical filters.

Enforcement: Fines are possible for sale, use, or distribution of prohibited sunscreens.

Why These Rules Exist

Scientific studies show that chemical sunscreen ingredients — especially oxybenzone and octinoxate — can:

  • Cause coral bleaching and kill young coral.
  • Accumulate in fish and marine life tissues.
  • Reduce reproductive success across species.
  • Even minute concentrations (as little as one drop in millions of gallons) can be harmful to coral systems.

Mineral sunscreens like zinc oxide and titanium dioxide act differently. They sit on the surface of your skin and physically reflect harmful UV rays rather than absorbing them, and they are recognized by the FDA as Generally Recognized as Safe and Effective (GRASE).

Sunscreen Ingredients to Avoid on Your Maui Vacation

Even products marketed as “reef-safe” can contain chemicals that still harm reefs and are not compliant with Maui sunscreen rules. Avoid the following commonly found sunscreen chemical ingredients:

  • Oxybenzone
  • Octinoxate
  • Octocrylene
  • Avobenzone
  • Homosalate
  • 4-Methylbenzylidene camphor
  • OD-PABA
  • Benzophenone-1 & Benzophenone-8
  • Nano-sized zinc oxide or titanium dioxide particles (if labeled nano)

These chemicals can either harm marine life directly when washed into the ocean or be absorbed into your skin and bloodstream.

How to Stay Compliant
  1. Check the label: The only active ingredients should be zinc oxide and/or titanium dioxide.
  2. Choose non-nano mineral sunscreens: Non-nano particles are recommended because they’re less likely to be taken up by marine organisms.
  3. Avoid sprays: These often contain chemical actives and can leave residue that washes off into the water.
  4. Complement with sun protection gear: Wear UPF clothing, rash guards, hats, and seek shade during peak UV hours (10am–2pm).
