Highlighted ingredients are regulated somewhere; red ones are restricted in at least one location we track. Dotted ones are listed below.
Fragrance allergens, essential oils and alcohol
- Drying alcohol: Alcohol Denat.
- Fragrance: listed as “Fragrance”. US labels don’t have to name the allergens inside a fragrance, so there may be more than this list shows.
The EU requires these allergens to be named on cosmetic labels above 0.001% in leave-on products (Regulation 1223/2009, Annex III). They can cause skin reactions in people who are sensitized; they don’t affect whether a sunscreen is legal anywhere we track.
Note: Labeled SPF 50+; stored as spf 50. Water resistance (40 minutes) from the FDA DailyMed label (setid 1d4b88d3-bee9-102c-e054-00144ff8d46c), whose ingredient list matches the brand page exactly. 3.4 fl oz size is sold at https://www.isdin.com/us/p/eryfotona-actinica-34-fl-oz/2794 with an identical ingredient list.
Common questions about ISDIN Eryfotona Actinica SPF 50+
Is ISDIN Eryfotona Actinica SPF 50+ reef safe?
“Reef safe” isn’t a regulated label claim, so we answer by law instead. It is allowed under the sunscreen laws of Hawaii statewide, Maui County, Hawaiʻi County (Big Island), the U.S. Virgin Islands, Aruba, Guam, the Northern Mariana Islands and Thailand's national parks, but not in Palau. Its only UV filters are minerals, which every law we track permits.
Is ISDIN Eryfotona Actinica SPF 50+ legal in Hawaii?
Under Hawaii’s statewide law (Act 104, which bans oxybenzone and octinoxate) it is allowed. In Maui County (Maui, Molokaʻi, Lānaʻi), which allows only mineral sunscreens, it is allowed. In Hawaiʻi County (the Big Island), which has a mineral-only rule for sales, it is allowed. Oʻahu and Kauaʻi have no county rule, so only the statewide law applies there.
Where is ISDIN Eryfotona Actinica SPF 50+ not allowed?
Palau: it contains phenoxyethanol, which is not allowed there.
Does ISDIN Eryfotona Actinica SPF 50+ contain oxybenzone?
No. It contains neither oxybenzone nor octinoxate, the two chemicals banned under Hawaii’s statewide law.
Is ISDIN Eryfotona Actinica SPF 50+ a mineral or chemical sunscreen?
Mineral. Its UV filter is zinc oxide 11%.
Is the zinc oxide in ISDIN Eryfotona Actinica SPF 50+ non-nano?
Its Drug Facts ingredient list doesn’t state particle size, and US labels aren’t required to. Many brands make non-nano claims elsewhere on the pack or website. No sunscreen law we track regulates nano particles.
Is ISDIN Eryfotona Actinica SPF 50+ water resistant?
Yes, for up to 40 minutes of swimming or sweating, according to its label. Reapply after 40 minutes in the water, immediately after towel drying, and at least every 2 hours.
What is the NDC for ISDIN Eryfotona Actinica SPF 50+?
ISDIN Eryfotona Actinica SPF 50+ is listed with the FDA under National Drug Code 69494-302. The NDC identifies this sunscreen on its FDA drug label (DailyMed); package sizes carry longer package NDCs.
