The Ordinary EUK 134 0.1%
Water-Free, High-Potency Antioxidant Formula
What It Is
EUK 134 0.1 % is a lightweight serum with a high concentration of EUK 134, one of the strongest antioxidants available.
What It Does
This treatment offers long-lasting protection from free radical damage and reduces visible redness.
- EUK 134: a self-regenerating antioxidant molecule that offers around-the-clock protection against free radical damage
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. While it has been around for many years, very few products on the market do use this truly superb antioxidant which can regenerate itself to offer round-the-clock antioxidant support. 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.
The low price of this formula does not reflect EUK 134's extremely high potency. EUK 134 is by far one of the strongest antioxidants available. While EUK 134 itself is very costly, the suggested concentration in any formula is below 0.05% and most formulas do not use this maximum suggestion. Our formula uses EUK 134 at an extremely high 0.1% concentration and we do not believe any product on the market today uses a higher concentration than this amount. This formula does not contain any water, silicones, oils or alcohol. Water can impair the stability of any antioxidant.
The Ordinary's antioxidant offering includes Resveratrol 3% + Ferulic Acid 3%. If you wish to take advantage of both formulas, either use them at different times or apply each in a separate step since acids and EUK 134 should not be mixed together. EUK 134 can also be mixed with most products such as Natural Moisturizing Factors + HA for a strong antioxidant boost.
EUK 134 is a third-party trademark and is used with permission.
Apply a few drops alone or after water-based treatments but before oils, moisturizers, and creams. Can be mixed with other non-acidic products for an antioxidant boost. Do not use with acidic treatments, such as those with ascorbic acid, glycolic acid, or ferulic acid. Strong acids can destroy EUK.
Do not refrigerate.

We are often asked to keep things simple so here it is... say a warm hello to ethylbisiminomethylguaiacol manganese chloride 🙈, also called EUK 134 (a "warm hello" because you'll feel a warming sensation when using EUK 134). In very simple terms, our new EUK 134 0.1% is a super-strong antioxidant that regenerates itself, unlike most antioxidants. It's best used once a day in the AM on its own or it can be mixed with non-acidic formulations if desired. Now the more complicated things... Everyone talks about antioxidants as if they're all basically the same thing. Almost everything from green tea to Vitamin C to hydroquinone is an antioxidant but most antioxidants are not able to regenerate as they scavenge free radicals. EUK 134 is a biomimetic of catalase and superoxide dismutase enzyme. It fights free radicals, reactive oxygen species (ROS) and hydrogen peroxide but after each antioxidant reaction, it regenerates itself so that it can undertake another antioxidant reaction. It's been shown to reduce visible redness and protect against appearance of UV damage. Now the PS: a) The formula is free of water, silicones, oils and alcohol; b) The 0.1% concentration is an extremely high concentration and more than 10 times the low suggested amount used in many formulations; c) EUK 134 has a brown hue. Other formulations that look more “elegant” in colour aren’t using any better form of EUK 134; they’re just using far less EUK 134; d) EUK 134 should not be combined with acids; they react very quickly (and we don’t understand why some formulas contain both acids and EUK 134); e) Don’t let the accessible price of this formula misguide you. Some brands claim that their EUK 134 costs more than $30,000+ per gram; trust us that they possibly meant $30,000+ per kilogram at most, a mistake that reflects an exaggeration of 1000 times. Yes, EUK 134 is expensive but no one we know uses anywhere close to the 0.1% that we use, which means the final formula doesn’t need to be inaccessible. ❤️🐒

It's slightly warming on the skin but it's something to be alarmed with.
I tend to use this after cleansing in the morning, following the caffeine solution for my eyes and the natural moisturising factors with a sunscreen.
Hi Sarah! We are so thrilled to hear that you are loving EUK 134 0.1%, and appreciate you for taking the time to write this review. Thanks so much!
Hi there! Thank you so much for these lovely words and your kind support ❤ It sounds like you may be applying too much product! About 2-3 drops of each should be applied and all product should be fully absorbed before applying next steps in your routine. You may also wish to apply HA 2% + B5 to damp skin to improve absorption and the ease of application if desired. We recommend avoiding unprotected solar exposure, gradually incorporating one new product into your regimen at a time and applying test patches first to see what works best for your skin. We hope this helps!

Hi Jen! EUK 134 doesn't have an intended age group, and can definitely be applied before the application of our Serum Foundation. We are happy to hear how much your are enjoying this product! 🐒❤
