Brand Overview

The Ordinary extols EUK 134 0.1% as a superhero antioxidant, but does it live up to the hype? The available research is intriguing—just keep in mind that skin’s complex needs are best served by a variety of antioxidants rather than just one.

EUK-134 is a trademarked ingredient also known as ethylbisiminomethylguaiacol manganese chloride. The skin-focused studies we found on this ingredient were linked back to Estee Lauder, who has a stake in DECIEM (The Ordinary’s parent company) and uses this ingredient in some of their products. While that could be seen as a conflict of interest, the results on isolated skin cells were confirmed in a lab setting and look promising for real-life use on a person’s skin.

What the research shows is that ethylbisiminomethylguaiacol manganese chloride mimics superoxide dismustase and catalase—both of which are enzymes that functions as a powerful antioxidants in skin. That backs up the claim that EUK 134 can interrupt free radical damage and offset oxidative stress, which minimizes the visible effects of UV damage.

In addition to the EUK-134 this simple, fragrance-free formula is made up of just one other ingredient: propanediol. The Ordinary claims to be using a 0.1% concentration of the EUK 134 so that leaves the major bulk of the formula to propanediol.

Propanediol is a penetration-enhancing hydrating ingredient that leaves a dewy finish on skin. At A nearly 100% concentration, it leaves a semi-greasy feel, almost like oily dew drops on the skin, and takes an unusually long time to absorb. In essence, it’s not the most pleasant texture (especially if you have oily skin to begin with).

Our final verdict: You’re better off sticking to more robust antioxidant formulas (one antioxidant can never do it all) with a more pleasant feel. Nevertheless, if you decide to give this a go, the UV-coated glass bottle helps keep the formula stable and ensures maximum potency.

  • Has the potential to fight off free radical damage
  • UV-protective packaging helps keep the formula stable and ensures maximum potency.
  • Fragrance free.
  • Skin does best with robust mix of antioxidants instead of just one.
  • Feels greasy and takes a long time to absorb.
Jar Packaging: No
Tested on animals: No

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.

It's not an overstatement to say that Canadian brand The Ordinary has taken the global beauty world by storm. In fact, no skincare line in recent memory has generated as much buzz as this brand!

Why all the commotion? Its because of The Ordinary's combination of clinical-looking products that contain high amounts of proven skincare ingredients and their unusually low prices (near rock-bottom prices). The curiosity to try these latte-priced products is intense; after all, you can assemble an impressive collection of anti-aging products for around the cost of one anti-aging product from a pricey department store brand!

The Ordinary is one of several brands that are part of a larger company, named DECIEM, whose tag line is The Abnormal Beauty Company, and with that we agree 100%. According to company founder Brandon Truaxe, DECIEM exists to create beauty brands with one mission common amongst them: to marry function, design and authenticity. Were not sure about the function, design, and authenticity part, but The Ordinary is certainly not ordinary at all in the world of beauty!

Frankly, we don't see how DECIEM can rationalize the low prices of The Ordinary products when the products from the other DECIEM skincare brands are so expensive. The difference is so glaringly strange it seems to border on a bait and switch - more about that in a moment.

Some of the ingredients in The Ordinary products are indeed inexpensive, but some of them absolutely qualify as expensive. These expensive ingredients are part of the reason why well-formulated anti-aging products, like serums and retinol treatments, typically cost much more than what The Ordinary charges.

The owner has been quoted as saying that the fill (fill is actual product inside the package) for his products costs less than $1 (less than $1 for how much? ). Depending on the formula, that can be true, but a skincare products retail price isn't just about whats inside the packaging, but also about how whats inside got there. There are costs for packaging, global regulatory testing, development, stability and safety testing, distribution, and on and on. Surely, The Ordinary didn't avoid some of these steps, but it does make us wonder.

We generally don't comment on a company's marketing strategy, but in this case its hard not to. We suspect The Ordinary is possibly a loss leader for the pricier DECIEM brands; that is, it gets DECIEM a ton of media and viral attention. Consumers, drawn by the low prices of The Ordinary, check out the site aiming to try the cheap stuff, but then, in sometimes not-so-subtle ways, they're lured into considering the expensive stuff from their other lines. Again, were just guessing here because its just so intriguing. Is The Ordinary a crusader for consumers or something else?

In terms of the quality of The Ordinary's products, the majority are one-note formulas. That is, rather than containing a robust mix of ingredients proven to help skin, most of their products focus on providing an efficacious amount of a single key ingredient, but to the exclusion of others. To give your skin an essential mix of antioxidants, skin-replenishing ingredients, and skin-restoring ingredients, you'd have to purchase several products from this line, and, since most of them have similar fluid-like serum textures, layering them, and knowing which product to apply first becomes a confusing guessing game. Plus, the Ordinary brand doesn't include sunscreens or cleansers, so it isn't one-stop shopping.

The Ordinary does one more unusual thing that reinforces their slogan of being The Abnormal Beauty Company: They routinely point out what they believe are the negative aspects of the very ingredients they use! For example, The Ordinary states clearly that it does not recommend exfoliating with AHA or BHA ingredients, but they sell AHA and BHA products. They also state they don't like silicones because of how they interact with certain ingredients, but they sell products that contain silicones.

They downplay retinol (vitamin A) as being inferior to other forms of vitamin A, but they still sell retinol products. Aside from the fact that these statements about retinol, AHAs, BHA, and silicones are wrong, its just bizarre to sell products you dont really want people to use, but then there's an allegedly superior, more expensive option from one of DECIEMs other brands, just waiting for you.

As you'll see from our reviews, there's a handful of The Ordinary's products worth checking out, but there are also several products that simply don't supply enough of what all skin types need to look and act younger, healthier, and more radiant. Low prices are great, but not when the trade-off is getting less than your skin deserves.
