What this solves
"Reef-safe" is a marketing word, not a regulated label. Most bottles labelled reef-safe still contain UV filters that damage coral at sub-parts-per-billion concentrations. The honest list of avoid-list chemicals is larger than the Bali ban (oxybenzone, octinoxate) — it also includes octocrylene, homosalate, avobenzone, and 4-MBC. Mineral filters (non-nano zinc oxide, titanium dioxide) are safer for reefs and for kids.
Who it's for. Snorkellers and divers buying sunscreen before a Penida day; parents packing for a Bali family beach trip; anyone who has been told at the dive shop to "wash off before entering the water".
Scan your sunscreen
Tick everything present on the ingredient list. The labels below use the same names a US/EU INCI label uses.
How to read the result
- Banned in Bali = oxybenzone or octinoxate present. Pergub No. 97/2018 prohibits use at Bali's protected reef zones; fines and reef patrols exist at marine park boundaries.
- Verdict — Safe (mineral only, non-nano), Marginal (some chemical filters, no banned ones), or Banned.
- Alternatives lists brands that publish their full INCI and use only non-nano mineral filters.
- Use case adjusts the recommendation: kids and sensitive skin should avoid chemical filters even if reef-safe.
Limitations
- The 2018 Bali ban is enforced at protected reefs and tourist snorkel sites, not everywhere. There's no in-store inspection.
- Mineral filters (zinc oxide, titanium dioxide) in nano form can still be ingested by marine life. Non-nano is better.
- Brands change formulations. Always read the current INCI; this tool checks the labels you tick, not a brand's marketing claim.
- Reef damage is one of many stressors (overfishing, plastic, runoff). Sunscreen is the easiest to fix, but not the only one.
FAQ
Is the Bali ban actually enforced?
At protected marine park boundaries (Nusa Penida Marine Protected Area, Menjangan, Bali Barat National Park) rangers can refuse entry or ask you to switch product. Day-to-day enforcement is patchy; the bigger argument is that the chemicals are scientifically documented to damage coral.
What about mineral sunscreens that stain wetsuits?
Non-nano zinc leaves a white cast on dark wetsuits. Apotheka and Stream2Sea formulations use finer particles that still count as non-nano (above 100 nm) but reduce the cast. Apply 15 min before suit-up.
What if I'm at a beach, not a reef?
The ban targets protected reef areas, not every beach. Kuta beach is not a protected reef. But runoff from your rinse-off reaches the reef — it always ends up somewhere downstream.
Are kids safer with mineral filters?
Yes. Oxybenzone and octinoxate are absorbed through skin; FDA has flagged them for further study. Pediatric dermatologists default to mineral (zinc / titanium) for under-6. Badger, Thinksport, and All Good make kid-formulated sticks and lotions.
