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: Water resistance from the FDA DailyMed label (setid d4f91d5a-600a-4255-a6e1-e7e7197848c7): 'use a water resistant sunscreen if swimming or sweating'. The brand list differs slightly from DailyMed: the brand has 'T-Butyl Alcohol' (not on DailyMed) and puts Tocopheryl Acetate before Polyacrylate Crosspolymer-6 (DailyMed has the reverse order).

Common questions about ISDIN Fusion Water MAGIC SPF 40
Is ISDIN Fusion Water MAGIC SPF 40 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 40 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 40 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 40 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 40 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 40 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.
What is the NDC for ISDIN Fusion Water MAGIC SPF 40?
ISDIN Fusion Water MAGIC SPF 40 is listed with the FDA under National Drug Code 69494-016. The NDC identifies this sunscreen on its FDA drug label (DailyMed); package sizes carry longer package NDCs.
