ISDIN Sunscreen Review: The Honest Truth About 7 of Their Most Popular SPFs

Last Updated on May 20, 2026 by Giorgia Guazzarotti

ISDIN is one of those brands that actually knows what it’s doing when it comes to sun protection. The filters are excellent, the textures are usually a dream, and you can tell there are actual dermatologists involved rather than just a marketing team throwing SPF on a moisturiser and calling it a sunscreen. But they’re not perfect and they know how to spin a story, so we went through seven of their top facial sunscreens to tell you which ones are worth it and which ones are basically charging you extra for ingredients that are there in such tiny amounts they might as well not bother. Let’s get started.

ISDIN Fusion Water Magic SPF 50 (£23.92)

This ISDIN sunscreen actually delivers on the “ultra-lightweight” promise and I say that as someone who rolls their eyes at every sunscreen claiming to be “invisible.”. This one is. You put it on and it genuinely just melts into your skin. No cast, no tackiness, no that horrible plasticky film that makes you feel like your face has been shrink-wrapped by midday. It sits under makeup without pilling, it doesn’t clog pores, and your skin just looks and feels like your skin, which is honestly the highest compliment you can pay a sunscreen.Where it falls down: this is not your outdoor, sporty, beach day SPF. Don’t even think about it. It doesn’t hold up against sweat or water, so if you’re planning any kind of actual sun exposure, you need something tougher. But for a daily city sunscreen that you’ll genuinely want to put on every morning without dreading it? This is one of the best-feeling options around. The filters are excellent and photostable, vitamin E gives you some antioxidant backup, and glycerin keeps things comfortable. It’s not doing anything revolutionary beyond the protection itself – but sometimes that’s exactly enough.

ISDIN Fusion Water Magic Repair SPF 50 (£27.25)

The texture of this face sunscreen is identical to the original Fusion Water Magic and honestly that’s the best thing about this product. It goes on beautifully, disappears into skin, no cast, no greasiness, wears perfectly under makeup. The sodium hyaluronate (a form of hyaluronic acid) gives you real, actual hydration too. So far so good. Here’s where I’m going to be annoying though: those peptides they’re using to justify the repair technology in the name and the higher price tag? They’re sitting at the absolute bottom of the ingredient list, after the preservatives. That means they’re almost certainly in trace, cosmetic amounts: enough to print on the box, not enough to do anything meaningful for your skin.

ISDIN Fotoprotector Fusion Fluid Mineral SPF 50 (£25.13)

Mineral sunscreens have earned their terrible reputation. Most of them go on like chalk paste and leave you looking like you’ve been lightly dusted with flour, which is not the vibe anyone is going for. This mineral sunscreen genuinely bucks that trend. It’s a fluid rather than a thick cream, and the nano-sized zinc oxide and titanium dioxide blend in far better than standard mineral filters, giving you broad-spectrum UVA and UVB protection without the ghostly finish. Is it completely invisible? No. But it’s about as close as mineral SPF gets right now, and for sensitive or chemically-intolerant skin, that trade-off is absolutely worth it.

Beyond the filters, it’s fragrance-free, water-resistant, and packed with soothing ingredients (allantoin, panthenol, sodium hyaluronate) that make it comfortable for reactive or atopic skin that tends to throw a fit at most products. The main watch-out is that alcohol denat sits fairly high in the formula, which might not be great news for very dry or compromised skin barriers. Also you have to shake it before use, which is one of those small annoyances you just have to accept. But if you’ve been struggling to find a mineral SPF that doesn’t make you look and feel terrible? This one is worth trying.

ISDIN Fotoprotector Extrem 90 Cream SPF 50+ (£19.76)

This is not a daily moisturising SPF and it’s not trying to be. The Extrem 90 is built for proper outdoor conditions (skiing, surfing, hiking, spending eight hours in direct sun at high altitude), the kind of situations where you need your sunscreen to actually stay on your face and not give up the second you start sweating or get splashed. There are both mineral and chemical filters working together, and the whole thing is water-resistant and designed to withstand friction. It does the job it was designed to do and it does it well.

The texture is a real cream (noticeably richer and more substantive than anything else in ISDIN’s lineup) and it leaves a luminous-but-not-shiny finish. Unfortunately, that goes hand in hand with a slight white residue, so if you’re on the deeper end of the skin tone spectrum, test it first. There’s squalane for moisture, bisabolol for soothing, and panthenol for barrier support, which makes sense because wind, cold, and UV exposure together are a brutal combination for your skin. It contains fragrance, and honestly the richer texture would probably feel heavy and uncomfortable for daily use for oily skin. But for what it’s actually designed for? It genuinely delivers.

ISDIN Fotoprotector HydroLotion SPF 50 (£26.93)

First things first:  this innovative formula isn’t as innovative as you may think. “Detoxifies skin” is not a thing. No sunscreen detoxifies anything. No skincare product detoxifies anything. Your liver detoxifies things. So mentally delete that entire part of the marketing, because it’s doing a lot of work to dress up what is, when you strip away the nonsense, a pleasant-to-use body sunscreen. It’s biphasic (oil and water phases that separate, so you shake it before use) and when you apply it you get this dry-oil texture that sinks in fast, moisturises without feeling heavy, and leaves no greasy residue whatsoever. In hot weather especially, that’s a very nice thing.  The filter system though is genuinely excellent – broad-spectrum, photostable, no white cast – and the dry-oil texture is one of the more enjoyable body sunscreen experiences around. Use it for what it actually is: a great body SPF with a lovely skin feel. 

ISDIN Fotoultra 100 Spot Prevent Color SPF 50+ (£21.85)

If your skin has a habit of pigmenting at the slightest provocation (sun spots, pregnancy melasma, the dark marks that linger after every breakout), this is doing a lot more than just protecting you from the sun’s UV rays. The niacinamide actively works to prevent new pigmentation from forming by interrupting melanin transfer, and the iron oxides in the tint shield against blue light. The texture is a lightweight fluid that gives light, skin-unifying coverage. Not a foundation, not full coverage, but enough to even things out and work as a makeup base. It’s also fragrance-free and pregnancy-safe, which matters because melasma and pregnancy are unfortunately very common bedfellows.

Just be honest with yourself about what it can and can’t do: this prevents new spots better than it fades existing ones. It’s your daily armour, not your treatment. If you’ve already got established dark spots you want to actively fade, the Active Unify is the better choice for that job. Use this one when you’re going to be out in the sun and you want to stop new damage from happening in the first place. Also worth knowing. It comes in a single tint shade, so if that doesn’t match your skin tone, the coverage aspect becomes irrelevant and you might prefer the untinted version.

ISDIN Fotoultra 100 Active Unify SPF 50+ (£27.20)

Where Spot Prevent plays defence, Active Unify plays offence – and that’s the key distinction between the two. This one is for skin that already has dark spots, whether from sun damage, melasma, or post-inflammatory pigmentation, and wants to actively work on reducing them while protecting against new ones. The DP3-Unify Complex goes after melanin from multiple angles: niacinamide stops melanin from being transferred to your skin cells, phenylethyl resorcinol blocks the enzyme that triggers melanin production in the first place, and the only evidence Tetrapeptide-30 works here comes form the manufacturer. The Fusion Fluid texture is elegant and lightweight, it doubles as a tinted base, and the filter system covers both UV and blue light.

The honest caveat is that the brightening actives are towards the lower end of the ingredient list, so results are VERY slow: we’re talking months of daily use, not a dramatic transformation in two weeks. This is not a replacement for a dedicated depigmenting serum if your pigmentation is significant and stubborn; it works best alongside one. Think of it as the SPF step in your anti-pigmentation routine rather than the whole routine. But as SPFs specifically designed for hyperpigmented skin go, this is one of the more thoughtfully formulated ones out there.

The Bottom Line

Overall, ISDIN is one of the more trustworthy sunscreen brands out there. When they focus on doing the core job well, they genuinely nail it. The filters are consistently excellent, the textures are some of the most wearable on the market, and if you’re someone who’s been skipping SPF because every other sunscreen feels disgusting on your face, there’s almost certainly something in this lineup that’ll change that. Where they lose me is when they start layering marketing claims on top of solid formulas that didn’t need them. Buy ISDIN for the broad spectrum sunscreens and the texture. Just don’t buy the hype on top of it.
