The best antioxidant available

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 very protective against environmental stressors. Love it.

hated it

This has a really heavy oil-like texture which doesn't absorb very well. However, i persisted using it daily for approx. 2 months and found my skin looked duller and really congested. In fact, I've stopped using it for about 2 weeks now and i've noticed my skin looks clearer, brighter and less congested. I would not recommend this serum.

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 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.

Best Use: Redness, Anti-Pollution

I bought it and used it because I needed an antioxidant serum that would kill the free radicals and prevent the damage on my skin so it can look healthy and young as much as possible. The formulation is pretty good, considering the pricing - especially. Feels light weight on the skin an very easy to use and incorporate in your routine. As for the results - skin kept looking healthy but did't notice a huge difference in my skin. But over all I am satisfied.

Best Use: Loss of Firmness, Anti-Pollution, Brightening, Anti-Aging

Value for Money!

I bought this about 3 weeks ago, and have been using it a few times a week. Initially I only saw the dewy effects when i applied it. But after using for a few weeks I have noticed my skin looks more luminous! I have been using another 'Ordinary' product alongside it. So unsure which is working to achieve this. But for the price... you can't really go wrong!

Best Use: Uneven Skin Tone, Hydration, Brightening
