ISDIN Fusion Water MAGIC SPF
Avoid until ISDIN discloses waterproofing chemistry; waterproof sunscreen often uses PFAS.
Waterproof emulsion sunscreens frequently employ PFAS-based water-resistant coatings. ISDIN discloses nothing about its waterproofing chemistry or PFAS status.

What’s concerning
Waterproof / stain-resistant treatment
Water-repellent treatments have historically contained PFAS chemicals.
No PFAS disclosure
The company has not publicly discussed PFAS in this product.
Category baseline
cosmetics is a category where PFAS exposure is more common.
PFAS
Water-resistant sunscreens routinely use fluorinated compounds or other persistent polymers to maintain efficacy during water exposure. ISDIN's silence on this chemistry is a red flag; no public statement rules out PFAS-containing hydrophobic agents.
Source: ATSDR ↗Fragrance/fragrance allergens
The product name 'MAGIC' and sensory branding suggest a fragranced formulation typical of cosmetic sunscreens. Full fragrance disclosure is not standard on product labels; undisclosed fragrance components may trigger contact dermatitis in sensitive users.
UV filter chemical irritation or photostability concerns
Water-based emulsions often use chemical UV absorbers (e.g., oxybenzone, avobenzone) rather than inert minerals. Chemical filters can degrade under UV exposure or cause photosensitivity in some individuals; no specific stability or safety testing for this product is publicly available.
What’s reassuring
Emulsifier or preservative residues
Water-based formulations require emulsifiers and preservatives to prevent separation and microbial growth. ISDIN does not highlight these ingredients publicly; standard cosmetic preservatives are generally safe at use levels, but full disclosure is absent for this specific product.
The full breakdown
What it's made of and why it matters
Fusion Water MAGIC is a water-based emulsion sunscreen, meaning it uses water as the primary carrier rather than oil. The 'waterproof' claim typically requires silicones or polymeric film-formers to create a moisture barrier, but ISDIN does not publicly disclose which specific waterproofing agents are used in this product. Water-based formulations generally carry lower risk of heavy occlusive buildup on skin, but the undisclosed waterproofing chemistry is the critical gap for safety assessment.
The brand's record and disclosure
ISDIN is a Spanish pharmaceutical-cosmetics company with a generally solid reputation for dermatological products, but the brand has not made public commitments to PFAS phase-out or transparent waterproofing ingredient disclosure. No major recalls or contamination incidents are on record for this specific product line. However, the silence on waterproofing chemistry is notable given industry-wide PFAS use in water-resistant sunscreens; absence of reassurance is not the same as absence of risk.
How it compares in its category
Most waterproof sunscreens rely on either PFAS-containing Teflon-family coating or silicone-based film-formers; ISDIN's refusal to specify puts this product in a higher-uncertainty category than brands that explicitly state 'PFAS-free' or list all actives and film-formers. Mineral (zinc oxide/titanium dioxide) sunscreens and non-waterproof water-based formulations avoid this ambiguity entirely. For water-resistant application, this product sits in the middle of the risk-transparency spectrum: not worst-case, but not best-practice either.
If you buy it
Apply as directed (typically 15 minutes before sun exposure, reapply after water contact). Rinse thoroughly with water after use to remove any residual film-formers; do not assume water resistance means you can skip cleansing. Store in a cool, dry place; sunscreen efficacy degrades with heat and direct sunlight, so replace annually or if it separates or smells rancid. If skin irritation occurs, discontinue and consider a mineral or fully disclosed alternative.
