The pocket money price tag of this formula belies its incredible potency – in fact, EUK 134 is one of the strongest antioxidants available, which can regenerate itself to offer round-the-clock defence from free radical damage. Neglected by the mass market, The Ordinary is bringing this innovative ingredient straight to your radiance regime – at an ultra-high (0.1%) concentration to maximise the age-defying effects.
Starring an exceptionally rare self-regenerating antioxidant, The Ordinary’s EUK 134 0.1% provides age-defying power offered by very few other products on the market. The pleasingly low price tag does not reflect its extremely high potency – while EUK 134 itself is very costly, the most common concentration for any formulation is below 0.05%, so The Ordinary’s 0.1% is impressively high, unmatched by any other product on the market.* Free from water, silicones, oils and alcohol (all of which can impair the stability of antioxidants) EUK 134 0.1% consists of an exceptionally rare self-generating molecule that neutralises free radicals, therefore preventing the production of collagen and elastin from being inhibited (which will keep skin plumper and more youthful). This potent product can also be mixed with others, such as The Ordinary’s {Natural Moisturizing Factors + HA}, for a strong antioxidant boost; however, it should not be used immediately with strong acids, as they will compromise its beneficial effects.
*According to The Ordinary’s research
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.

Nice
I like this serum although it gives me a sense of heat as I massage it on my face and I am not sure it is normal. So far I cannot say whether it has any antiageing power but it surely leaves my skin soother and brighter.

Essential
This is an essential part of my routine, it helps keep my skin clear and even and gives it a lovely sheen under my tinted spf

Best thing ever!
I have been using this serum for the last 5 years and I love it. I read in the comments that people don't know how to incorporate it in their routine, so I will tell you how I do it and it is the best thing ever. First I should say that I have a very problematic, adult acne, combination, textured, aging, sensitive skin (I am 46 yo). This serum just makes everything better. So the way to use it is put a very small amount on in the morning, after cleaning the face and putting on a cream, and before putting on the face sunscreen. This makes the sunscreen go on very smoothly and also boosts the anti-aging effects of the sunscreen. And on top of that (and this is the main reason I love EUK so much), the foundation goes on like a dream. It doesn't cling on to any dryness or texture, and lasts all day. Just try it out you will not regret it. I have been doing this for years, with various creams underneath, various sunscreens and various foundations. It always works. Like I have put on some expensive primer. And there is the benefit that it is a serum that prevents aging. As a result, I am looking the same now at 46, if not better, as when I was 41.

A super antioxidant, easy to add to a routine.
What I love about this serum is that it is such a good way to add an additional protection to your skin within an existing routine. It didn’t trigger my skin in any way and I saw an improvement in appearance. I do suggest though to switch antioxidants after a while. I do chose another antioxidant  each time I finish a flask. :)Â

Great but I can’t fit it in my routine
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 or retinol 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.

Great product!
I use it on my dry skin before applying make-up and it is GEAR! My skin is hydrated and glows. However don´t use too much. Even on dry skin 3-4 drops are enough for a full face. When you apply it on your skin, it gets quite warm. It´s very nice ,especially during cold mornings.

Amazing
I have just ordered my second bottle of this as it’s fast become my favourite skincare product. A little goes a long way so the bottle lasts an incredibly long time and the formula works!!

Holy Grail
I never knew that this was so strong. My skin is very dry in the winter months and extremely oil in the summer, so I use it when i am on the drier side. Only after a week my post acne scars are healing super fast, my skin tone looks even and brighter and the little milia i had near the bridge of my nose and in the corner of my eye are disappearing. And nothing else has helped with the milia so far. I love it so much, use it under my moisturizer then top it off with watermelon seed oil and my skin just glows
