“Mirror, mirror on the wall, who is the most powerful antioxidant of all?” “From now on, Vitamin C, you’re number two. Superoxide dismutase is more powerful than you.” It’s a good thing that vitamin C isn’t the jealous type. It knows that no antioxidant can do the entire antiaging job alone. But if there’s anyone that can give vitamin C a run for its money and threaten its status as the darling of the antioxidant world, that is superoxide dismutase. This antioxidant has what it takes to neutralise the most dangerous type of free radicals – and then some. Here’s all you need to know about it, including what the best products with superoxide dismutase are and how to incorporate them into your skincare routine:
What Is Superoxide Dismutase?
Superoxide dismutase (SOD) is an antioxidant enzyme. WTH? Antioxidant enzymes are enzymes that behave like antioxidants. Your body naturally produces them when your cells are being attacked by free radicals to reduce DNA damage. FYI: there are 3 forms of superoxide dismutase: copper, manganese and zinc.

What Does Superoxide Dismutase Do?
Superoxide dismutase is the archenemy of Superoxide radical. Superoxide is the most common free radical in the body. It’s also the primary trigger of inflammation, a process that destroys collagen and elastin and leaves you with wrinkles and dark spots. Superoxide is so bad because it has a long life and is very reactive:
- When it reacts with another Superoxide radicals, it forms Hydrogen Peroxide.
- When it reacts with hydrogen peroxide, it forms Hydroxyl Radical (the worst type of free radical ever).
- When it reacts with an unsaturated fatty acid, it forms Lipid Peroxide.
Superoxide dismutase hunts down Superoxide and converts it into oxygen and hdyrogen peroxide so it can’t wreak damage on your cells and give you wrinkles anymore.

Who Should Use Superoxide Dismutase?
If you’re over 25 and want to keep your skin looking fresh, SOD should be on your radar. Your body’s natural SOD production starts tanking as you get older (because of course it does), which means you need all the help you can get.
SOD is a godsend for anyone battling redness and inflammation. Got skin that freaks out at the drop of a hat? Always dealing with irritation? This is your guy. It’s gentle enough for sensitive skin but powerful enough to actually make a difference.
City dwellers, this one’s for you too. All that pollution is basically a free radical party on your face, and SOD is the bouncer that kicks them out. Same if you’re dealing with acne – inflammation is a huge part of breakouts, and SOD tackles that head-on.
How To Use It In Your Routine
Good news: SOD isn’t a diva. It plays nice with basically everything else in your routine. If you’ve got a serum, slap it on after cleansing but before your heavier creams. The Niod mist? That baby can be spritzed on whenever your skin needs a pick-me-up throughout the day. It’s like a coffee break for your face.
Moisturizer with SOD? Use it as your last step before sunscreen in the morning, or as your night cream. And yes, you still need sunscreen – SOD fights free radicals like a champ, but it won’t protect you from UV damage.
You can use SOD morning and night, and it actually loves hanging out with vitamin C (told you they weren’t rivals). Same with vitamin E, niacinamide, and retinol. Just remember: thin to thick when you’re layering products.
Side Effects
Here’s the best part: SOD barely has any. Since your body already makes it naturally, your skin usually doesn’t freak out. It’s way gentler than vitamin C, which can sometimes sting like hell. That said, patch test new stuff anyway – not because of the SOD, but because other ingredients in the formula might not agree with you. Dab a bit behind your ear or on your inner arm for a day or two before going full face.
Super sensitive skin or dealing with rosacea? Start slow. Every other day at first, then ramp up if your skin’s happy. One heads up: these products are pricey and rare, so store them properly. Away from light and heat, lid on tight. You don’t want your expensive serum turning into expensive garbage.
FAQs
Is superoxide dismutase better than vitamin C?
Okay look, they’re not even fighting each other. It’s like asking if pizza is better than tacos – they’re both amazing and do different things! SOD hunts down those superoxide bastards specifically, vitamin C is out here fighting other free radicals and brightening skin. Honestly just use both and stop overthinking it. But like if I HAD to choose – vitamin C if you want to look brighter and glowier, SOD if your face is always red and pissed off.
Can superoxide dismutase be used during pregnancy or breastfeeding?
I mean your body already makes it so it’s probably totally fine? But dude I’m not your doctor and pregnancy makes everything weird. Just text your OB and ask. Takes two seconds and then you don’t have to worry about it. Last thing you need is to be googling this at 2am freaking yourself out.
How long does it take to see results from superoxide dismutase?
Ugh not gonna lie, it takes a while. Like maybe a few weeks before your skin stops being such a drama queen and calms down. But the real good stuff? Couple months at least. I know that sucks to hear but it’s not like retinol where you wake up peeling. It’s more like… preventing your future wrinkles from showing up? So you won’t even know it’s working but trust me it is.
Why isn’t superoxide dismutase in more skincare products?
Because it’s a massive pain in the ass to work with, that’s why. It literally falls apart if you look at it wrong. Light? Dead. Heat? Dead. Air? Also dead. So most brands are like “yeah no thanks” because it costs a fortune to stabilize it properly. Only the fancy brands with actual chemists and budgets bother. Which sucks for us but whatever.
How often should superoxide dismutase be used?
Every day babe. Free radicals don’t take days off so neither should your SOD. But if your skin is being sensitive, start with every other day and see how it goes. Once your face isn’t freaking out, go daily.
Can superoxide dismutase products expire or lose potency?
Oh for sure. If it smells weird, looks different, or feels gross, chuck it immediately. You’re literally just rubbing useless goop on your face at that point. Most stuff lasts like 6-12 months after you open it but only if you’re not leaving it in a hot bathroom or whatever. There’s usually a little symbol on the bottle that tells you. And honestly when you’re not sure just buy a new one, these products are too expensive to waste your time with expired crap.
What Are The Best Products With Superoxide Dismutase?
If superoxide dismutase is so powerful, why do so few products have it? It’s very tricky to work with (like vitamin C, it’s very unstable). But that makes the few products available all the more precious and worth snapping up. Here are my fave picks:
- iS Clinical Reparative Moisture Emulsion ($110.00): A super hydrating serum with Superoxide Dismutase to plump up skin and prevent wrinkles. Available at Dermstore, Face The Future, isClinical and SpaceNK
- Niod Superoxide Dismutase Saccharide Mist (£40.00): An anti-aging mist with Superoxide Dismutase you can spritz on your face during the day to keep up your anti-aging protection. Available at Niod and SpaceNK
- Paula’s Choice Resist Anti-Aging Antioxidant Serum ($49.00): An anti-aging serum with every antioxidant under the sun, including Superoxide Dismutase. Available at Dermstore and Paula’s Choice
The Bottom Line
Perhaps the mirror was exaggerating a little when it called superoxide dismutase the most powerful antioxidant of all. But it’s the one that fights the worst types of free radicals so it would be silly to ignore it. Add it to your skincare routine to give your other antioxidants a helping hand. I already have.
Your post, as always, is so informative. And timely, at least for me.
I just purchased the PC RESIST Ultra-Light Super Antioxidant Concentrate Serum along with the PC RESIST Super-Light Wrinkle Defense SPF 30.
Planning on using in my morning routine in the following order:
Cleanse
Tone
Vit C
Antioxidant Concentrate Serum
Wrinkle Defense SPF 30
Cindy, great choice of products and perfect order. 🙂
I haven’t seen a lot of focus on Superoxide dismutase -glad you are highlighting it. I used to use the PC Resist serum but it has gotten increasingly expensive since I started with PC a decade ago. I still use it when I travel because the tube is so travel friendly and the silicones are very soothing on my skin. I now use the skinactive antioxidant serum (that you featured in an old post). It also has Superoxide dismutase, and is a bargain at 22USD.
Meg, it’s a shame it isn’t in more serums, isn’t it? It’s one of the most powerful antioxidants out there.
Im so glad i was sent this a while back because of late i refuse to support deciem all of the bullshit that as gone on lately is insane
http://www.beautyandtheboy.com
Andrew, I agree. I still get a lot of requests to feature/review Deciem from readers but it’s becoming increasingly difficult to buy the products for myself. I’m finishing using/reviewing what I have and then we’ll see. It’s obvious there’s a problem with mental illness/addiction here and I really hope he can get the help he needs and stop this train wreak.
I’m sorry, I’m late on this post… I would very much like to know what you mean by “…it’s becoming increasingly difficult to buy the products for myself.” when talking about Deciem? I follow all your posts on their products (I bought a lot of them recently), that’s why I would like to know 🙂 Thanks!
Brigitte, I wrote this comment at a time when Deciem’s founder was alienating customers with his erratic behaviour, including insulting customers and anyone who didn’t agree with him. There are plenty of articles around this drama on the internet. But that’s all in the past. Brandon has sadly passed away recently and the company is in different hands now.
Thanks for your response, much appreciated. I love Niod products which I discovered thanks to you 🙂
KYPRIS Antioxidant Dew is lovely (has plenty of Ferulic acid as well) although very pricey. I wish more companies offered smaller amounts with equally smaller costs, especially given that the effectiveness expires.
Fynl, that’s good to know. And I agree. You don’t want expensive products to stop working when they’re still half full. 🙁
does PC have this ingredient, superoxide dismutase, in a serum for combination skin? The Resist line is for dry skin. Thank you!
Kathy, unfortunately I don’t think so. The Resist line is for signs of aging so a lightweight formula like a serum may be ok for combo skin too. If you can, try to get hold of a sample so you can test it before buying.
If I decide to purchase the Niod mist, do I put that on before of after my Vit C serum?
Jean, use it before Vitamin C.
Thanks for the recommendation 🙂 i am giving it a try! Can I use it at night before my retin-a?
Joanne, yes you can.
It sounds amazing! If I purchase the Niod mist and it is unstable like vitamin c, how soon should it be used to still be effective? Can it replace vitamin c completely with all the same benefits? 🙂
Sofie, Niod uses a stable form of SOD so I wouldn’t worry too much about longevity. Just as long as you don’t forget in a drawer for months, you should be fine.
Unfortunately, antioxidants aren’t replaceable. There are many types of free radicals out there, so the more antioxidants you use, the more types you can destroy. If you want to keep your skincare routine short, just use them on alternate days.
Thanks for putting this on the map more widely!
Question: I’ve read that The Ordinary’s “EUK 134” is basically SuperoxideM.
It’s also a bit tricky to put into one’s morning routine as it’s notoriously unstable.
Are there any hints you could give as to where to put it in your routine?
I’ve read the above, but would like to find out more about it, unfortunately too many things I found on the internet are rather vague.
I’d love to use it, but don’t want it to be destroyed too quickly despite applying sunscreen etc.
Thank you in advance!
Christine, if you’re worried, use the NIOD mist. It uses a form of SM that’s stable.
If you want to use EUK, apply straight after cleansing and then sunscreen. You can use something else in between if you need to. Just not acids, as they will destroy SM.
Again, if you’re in doubt, just alternate your morning routine. On some days, cleanse, EUK and sunscreen. Other days, cleanse, use your usual serums and moisturizers and then sunscreen.
Your skin needs SM but you don’t need to give it a dose every day if you wanna use other actives too.
My understanding is that The Ordinary EUK 134 0.1% is a mimetic of Superoxide Dismutase. Does that mean that it is redundant to use both in the same skincare regimen? If so, is one more effective than the other?
Makemineirish, when it comes to antioxidants, the more the merrier. If you can afford it, you can indeed use both,
hi gio! can i use EUK 134 TOGETHER WITH CAIS, RETINOL, niacinamide & superoxide ?
Camila. yes you can but AGAIN, use only what you need.
and also which one i use first? EUK OR SUPEROXIDE?
Camila, this is redundant. Pick one!!

Victoria, that’s a great post 🙂
Hi Gio
Can I use NIOD Survival 30 with Skin ceuticals ferulic C E? Not sure if the superoxide dimutase would upset the vitamin C.
Thanks
Danielle
(PS love the blog and your youtube videos)
Danielle, just wait 10/20 minutes in between application and you’ll be fine.
Hi Gio, I love your blog and emails, read them religiously! I’ve been using this mist for a while, and follow with multi molecular hyaluronic and Timeless Vit C (and copper peptides a few times a week). I’m always rushed in the morning and don’t wait more than a minute or so between each layer. Just reading the above commentary, I’m concerned the SDSM might be impacting the efficacy of the vitamin c? Should I be waiting longer or am I ok to keep on as i have been? Thanks
