What is The Ordinary EUK 134 & what does it do?
This is Deciem´s simplified explanation:
EUK-134™ is a biomimetic of two enzymes that are naturally occurring in the skin: superoxide dismutase and catalase. The exciting thing about EUK-134™ is its ability to regenerate itself (a quality unique to EUK-134™), which means that it only needs to be applied once daily to offer long-lasting antioxidant support. EUK-134™ has been shown to reduce the appearance of visible redness and photoaging.

GZG says: I use EUK 134 in the mornings after serum but before cream (sometimes I put a few drops and mix it with cream) Suits perfectly my hypersensitive easily irritated dry skin. It feels well hydrated after the application. When it comes to results, I haven’t noticed much difference but I guess it goes for all the antioxidants. It’s more about prevention, I guess. An overall very nice product to use.
