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.

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.
Patch tests are an easy way to help predict if you may experience a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating any new product into your regimen. We have outlined a general method for conducting your own patch test below based on the type of product.
Apply a small amount of the product onto a clean area of skin on the upper forearm.
Keep the area dry.
If the product has a specified duration of use, rinse off after this time has elapsed. Otherwise rinse off after 24 hours.
If any redness, burning, itching, blistering or irritation is observed at any time throughout the test, do not use the product.
