The Ordinary EUK 134 0.1% 30ml
Water-Free, High-Potency Antioxidant Formula EUK-134 is a mimetic of superoxide dismutase and catalase, forming an exceptionally rare self-regenerating molecule that scavenges superoxide free radicals, eliminates hydrogen peroxide and converts reactive oxygen species into water and oxygen. The only issue with EUK-134 is that it must not be used immediately with strong acids such as suspensions of Ascorbic Acid. Strong acids will completely destroy EUK-134 which is based on manganese. Directions Apply alone or after water-based serums, before oils or heavier creams. Alternatively, mix with other treatments to enhance their antioxidant capacity significantly. Do not use with highly acidic formulations such as suspensions of ascorbic acid. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children.

Hello beautiful people, I just want to share something I've learned about using euk134 on my own face. I found that if the night before I use azelaic acid or when I use niacinamide before uk 134, I tend to have a reaction that results in red blotches. I think because these products are so potent, it can get a little too much for our skin sometimes.If you get a reaction I would first try to use euk134 on 'calm skin', and if you still get a reaction to mix a drop of euk134 in some natural moisturising factors cream. I find that to be a super nice combo, they work so well together and it dilutes the potency of the euk134 so it might be the trick to get your skin used to it.I hope this helps some of you!

I have regretted not repurchasing this product after it ran out! I initially bought it to see if adding it to my regiment could help improve my skin barrier, because my face is extremely dry, reactive/sensitive and at that time was covered in eczema (probably due to a combo of perimenopause and some very stressful life events).NOTE; I changed/added one product at a time, so I could tell what the effect was. After adding the EUK 134, my regimen consisted of:- Squalene cleanser- Hyaluronic acid + b5 applied to wet skin after rinsing off cleanser- EUK 134- TO Moisturizer (which I can never remember the name of - hydrating something something ;))- a few drops of oil (I normally use a mix of hemp oil and other oils like rosehip and sea buckthorn)My skin did ...

After a few days of use, I noticed that my skin was less reactive to cold or heat, and a lot calmer overall. After about a week, my eczema was pretty much gone, and my skin continued to feel calmer - no more dryness and itchyness!And then I made the mistake of not repurchasing (what was I thinking??) My routine otherwise has not changed, but the eczema is back! Buying again RIGHT NOW. If your skin is very reactive, do try it! If it's too strong, try mixing it with your moisturizer.PS DECIEM, why is there no option "sensitivity/reactivity" in the dropdown menu when selecting products?? Us sensitive creatures want to be able to select only those products that are less likely to sting and burn and make our eyes water, please!! (Yes, that has happened to me - I applied a face mask from an unnamed brand, ahem, and immediately had to wash it off with cold water because it stung so bad it made me howl and made my eyes water!)

This is a great antioxidant product, but I just can’t find a way to fit into my routine. As per The Ordinary’s instructions, this shouldn’t be used in the same routine as most other actives like vitamin C and chemical exfoliants. I tried going without vitamin C in my morning routine and using this instead but, in the end, if I must choose one, I prefer having vitamin C which a more proven ingredient that gives me multiple visible benefits. If I use it at night, I have to go without my copper peptides which is also a deal breaker. I also don’t love the heavy oily finish of it. So, in the end, it doesn't align with my skincare goals but I would recommend for a young skin.

I can't pinpoint exactly what EUK 134 0.1% does to my skin. This is expected as antioxidants are preventive. I do notice a difference when I don't use it though. I guess it's the glow, not sure really.The only issue I have with the product is that it's too drying for my skin. Even 2 drops of the product leave my skin dry and wrinkly. I had the same problem with TO's Resveratrol, which was why I switched to this product. I don't know if the problem is with the Propanediol base, or if these antioxidants are just drying.Luckily for me, I have a big bottle of sunscreen that I stopped using because it was a greasy mess for me. I've now put that sunscreen to good use by pairing it with EUK. It's a fantastic combo!!! I’m glowing like the sun……glass skin on fleek! Can't ...

The product is oily and rich. One drop per zone is enough. I have tested the product 3 times on my sensitive skin. As mentioned, using it in minimal doses. During the first time, I have applied it on my clean face during the morning, after using Multi Molecular Hyaluronic Complex the night before. After one hour It started to itch on my cheeks, and appearing like a rash with visible signs of redness. Nothing on my brow. So I retried it after another day, without using any product during the 12 hours before. Same result, with redness on my brow. After a few days, I re-tried and it continues to cause redness. The effect lasts for a few hours. Better to be used at night. A part from that, I noticed that wrinkles were less visible. That is good. On the contrary, my ... MoreThe product is oily and rich.

Ok I finally worked this product out. I purchased this product to apply when I am gardening. I used Matrixyl on wet skin added argireline to targeted areas then applied Euk 134 then TO 30 spf. It did not absorb very well on my thick normal to oily skin but I was willing to put up with it for protection. I saw no improvement in my skin and my skin looked greasy. I then went out in the garden and was exposed to strong sun that’s when the magic happened. The sun or free radicals is what activated this product. 10 minutia later the product was fully absorbed no greasiness, but that was not the best thing when I came back in to look at effects on skin my skin was transformed. Even clear skin that was glowing and no sight of redness. After 4 hours of gardening my skin was ... MoreOk I finally worked this product out. I purchased this product to apply when I am gardening.

Even clear skin that was glowing and no sight of redness. After 4 hours of gardening my skin was so beautiful no dirt or effects of sun. It is being exposed to free radicals that activates this product. The glow rivalled vitamin c and took years of my skin 20 years ago was the last time I saw my skin looking like that. The reason it has not got 5 stars is I don’t think the formula is right for my skin and can be off putting at first. If it had a nicer base I think this product would be hugely popular. My preference would be Squalane. I will continue using this product for gardening, but if it was in Squalane It would be everyday and bye bye vitamin c. My product was brown another reviewer said it was reformulated and is now a clear liquid. I can’t wait to try that formula.
I don't know what voodoo is in this product, but it's seriously magic in a bottle. It has smoothed out my skin to the point that my one smile line near my nose is disappearing. My skin has an amazing glow that I've never been able to achieve with other products. During the day, I mix two drops with a drop of the Ordinary's Marula Oil, which is just enough to cover my entire face. At night, I apply it directly after my toner. It feels a little heavy upon application, but give it a few minutes to sink in and that feeling will go away. I promise - it's worth it!
Wow! Like that formula so much.Use it every morning before my day routine. Work well. After using my day cream no oily feeling anymore. I use to be a medical esthetician and worked with skinceutical product. It save my bad adult acne. But right now that I'm fine. I am using all my skin-care routine with ordinary and my skin is pretty. Because of the price and the formula who look strangely something similar to skinceutical with different formula. I'm really surprised about everything they have. Just need to be careful not to take products that do not fit together. And absolutely worth its 5 stars.
This must be the most underrated skincare product on the planet. No one talks about this! But EUK 134 works faster and more effectively than anything else I’ve tried in reducing redness and hyperpigmentation. Better yet, I’ve never had any kind of bad reaction to it. It’s warm when it goes on, but that subsides. On my skin, it has been superior to Vitamin C and AHAs when it comes to immediate effect—I still use the others because research shows how important they are long-term. I saw real results within *a week,* significant enough that friends commented.I am guessing a lot of people steer clear of this one also because it has so many conflicts, but it *does* work with retinoids. Depending on your own skin type, it would go well over or under your retinoid. It is ... MoreThis must be the most underrated skincare product on the planet. No one talks about this!

Depending on your own skin type, it would go well over or under your retinoid. It is such a powerful antioxidant that I also like wearing it alone in the daytime under my SPF. If I am not mistaken, this is the top ingredient in Estée Lauder’s iconic Advanced Night Repair. This, as you can see, is $10. And it is the only skincare (other than SPF) that I absolutely cannot do without.
This was The founder of TO favourite product. I can see why. It’s such a high potency percentage for such a good price. Compared with other places selling EUK 134 this is a bargain. It really helps settle my redness and now I’ve used it for a few years I can see that my skin looks overall much better than it did before use. I put it on as one of my last steps before moisturiser at night. If I am using tretinoin that night I wait 20 mins to half an hour for it to absorb then put on my tret. If using acids put them on first and give them time to fully sink on and then apply this and the rest of your skincare. The great thing about EUK 134 is as soon as it sinks into the skin it will continue working until you wash it off. That’s actually backed up by research. It’s ...
