One just landed in the US after a decade of global success. The other? Already a staple at the dermatologist’s office and on beauty store shelves. And both have 50 years of skin and sun care science behind them.
ISDIN sunscreens consistently rank most-loved by aestheticians, experts, and Isdinlovers alike. So it makes sense that they’re also the products you have the most questions about. If you’ve been wondering what the difference is between Eryfotona Actinica and Fusion Water MAGIC, we’re only too happy to help.
Read on to learn more about these two fan-favorite sunscreens, including which characteristics they share and which set them apart.

What do these ISDIN sunscreens have in common?
Ultralight texture
With non-greasy, invisible finishes, these lightweight formulas defy even the most common sunscreen objections. They both absorb quickly, melting into the skin and leaving only a silky feeling behind. Plus, they’re non-comedogenic and suitable for all skin types.
Trusted protection
Another important feature? Both offer high SPF broad spectrum sun protection tested by dermatologists. With a half-century of expertise, we take skin health seriously, providing you with sunscreens to do the same.
Advanced ingredients
Both represent the latest in sun care innovation—adding skincare benefits to your daily SPF. Each sunscreen features its own combination of antioxidants, moisturizers, and plant extracts to help combat the effects of everyday skin stressors, beyond just the sun.
Fusion Water MAGIC, the hydrating daily sunscreen with 360° protection
The sun isn’t the only thing to consider when it comes to protecting your skin. Other lifestyle and environmental factors, known together as the exposome, affect how your skin ages and responds to the world.
Pollution, tobacco smoke, and even the climate you live in—with so many things to consider, how can you stay ahead of it all? Enter Fusion Water MAGIC. Its advanced formula boasts SPF 40 sun protection while helping to defend against free radical damage from blue light, pollution, infrared, and heat.
On top of 360° protection, you can’t forget aesthetics (and don’t worry, we didn’t!). In fact, Fusion Water MAGIC got its name for its beloved texture. Perfect under makeup or on its own, the ultralight, hydrating formula lends a smooth, invisible finish.
Fusion Water MAGIC might be for you if:
- You’d like a high SPF sunscreen with built-in skincare benefits
- You’re looking for a hydrating finish that works well under makeup or on its own
- You’d like an ultralight texture with no white cast, pilling, or greasy feeling
- You’re focused on delaying the appearance of your first fine lines and wrinkles
- You’re living in a hot climate or constantly facing high temperatures
First things first, what’s behind the name Actinica? In the world of dermatology, sun damage is also called actinic damage.
Here’s what it refers to: Getting too much sun can overwhelm your skin’s natural repair mechanisms, which usually help protect it from outside stressors. Over the years, this can cause wrinkles, sun spots, and even the potential for pre-cancerous or cancerous lesions.
But what if you could protect your skin and help repair the effects of past damage? Enter Eryfotona Actinica featuring DNA Repairsomes®️. Otherwise known as photolyase, DNA Repairsomes®️is a plankton extract that helps recognize and fix UV-induced skin damage.
Eryfotona Actinica might be for you if:
- Your aesthetician or dermatologist has recommended it post-treatment
- You’ve noticed a few signs of sun damage and photoaging and want to soften them
- You’re looking for a very high SPF with an invisible finish
- You’d prefer a water-resistant sunscreen
- All-mineral formulas are important to you
Which one’s right for my skin: Eryfotona Actinica or Fusion Water MAGIC?
Both offer expert daily protection and a texture you’ll actually enjoy putting on. But each offers an extra for your skin that depends on your goals.
- Fusion Water MAGIC is an all-around favorite, winning over both sunscreen newbies and skincare experts with 12-hour hydration*, invisible coverage, and 360° protection from pollution, blue light, and heat damage.
- Eryfotona Actinica is a premium choice for maturing skin to help repair signs of sun damage or for those who’d like an ultralight all-mineral, water-resistant formula with a very high SPF.
The best news? You don’t have to choose. As long as you’re reapplying sunscreen at least every two hours, reach for one or the other as they fit your needs.
