“—” means no specific record for that ingredient in that jurisdiction's lists — it is not an approval. Restricted ingredients are allowed within limits (concentration, product type, label warnings); a product listing one is not necessarily over the limit. How we check.

Can I take it to Hawaii? — reef sunscreen laws

Checked against this formula's UV filters (Zinc Oxide). These laws cover sunscreens sold — and in some places used — without a prescription.

PlaceResultWhyLaw · since
State of Hawaii OK None of the banned filters HRS §342D-21 (Act 104, 2018) · 2021-01-01

Key West, FLNot enforcedThe 2019 ban on oxybenzone/octinoxate was preempted by Florida law (Fla. Stat. §499.002(7), 2020).Ord. 19-03

Hawaii state and U.S. Virgin Islands laws exclude products sold as face cosmetics without a sunscreen claim; SPF products are sunscreens. Information only — check the latest rules before you travel.

Storage & heat

Official storage statements

“Protect the product in this container from excessive heat and direct sun.” — Required 'Other information' statement for sunscreens sold in the U.S. (FDA OTC Monograph M020)

“Keep out of direct sunlight. Keep out of reach of children.” — Common precautions required on all cosmetics in Korea (Cosmetics Act Enforcement Rule, Annex 3)

On the brand's product page

“Store away from excessive heat and sunlight”

Our note — heat, light & air

This formula lists ingredients that are known to break down faster in heat, light or air:

Don't leave sunscreen in a hot car or in direct sun on the beach — heat can separate the formula and lower protection.

Other markets
