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
- 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: Discontinued: not on isdin.com/us; ingredients from an older FDA DailyMed label (setid 1b7ddac8-9001-4ba8-9feb-95f15069b0b9). The Drug Facts say to use a water resistant sunscreen if swimming or sweating. Replaced by Fusion Water MAGIC SPF 40.
Common questions about ISDIN Fusion Water MAGIC SPF 30
Is ISDIN Fusion Water MAGIC SPF 30 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, Aruba, the Northern Mariana Islands and Thailand's national parks, but not in Maui County, Hawaiʻi County (Big Island), the U.S. Virgin Islands, Palau and Guam. Labels like “Hawaii Act 104 compliant” only mean a product has no oxybenzone or octinoxate; they don’t make a chemical sunscreen legal on Maui or the Big Island.
Is ISDIN Fusion Water MAGIC SPF 30 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 not allowed because it contains octocrylene, homosalate, octisalate and avobenzone, and Maui’s rule covers using it there, not just selling it. In Hawaiʻi County (the Big Island), which has a mineral-only rule for sales, it is not allowed. Oʻahu and Kauaʻi have no county rule, so only the statewide law applies there.
Where is ISDIN Fusion Water MAGIC SPF 30 not allowed?
Maui County: it contains octocrylene, homosalate, octisalate and avobenzone, which are not allowed there. Hawaiʻi County (Big Island): it contains octocrylene, homosalate, octisalate and avobenzone, which are not allowed there. The U.S. Virgin Islands: it contains octocrylene, which is not allowed there. Palau: it contains octocrylene, avobenzone, homosalate and octisalate, which are not allowed there. Guam: it contains octocrylene, which is not allowed there.
Does ISDIN Fusion Water MAGIC SPF 30 contain oxybenzone?
No. It contains neither oxybenzone nor octinoxate, the two chemicals banned under Hawaii’s statewide law. Being oxybenzone-free does not make it mineral: it still uses chemical UV filters.
Is ISDIN Fusion Water MAGIC SPF 30 a mineral or chemical sunscreen?
Chemical. Its UV filters are octocrylene 9%, homosalate 7.3%, octisalate 4.5% and avobenzone 2.7%.
Is ISDIN Fusion Water MAGIC SPF 30 water resistant?
No. It makes no water-resistance claim, so it isn’t meant for swimming or heavy sweating. Use a water-resistant sunscreen for time in the water.
