EUK 134 0.1%
EUK 134™ 0.1%, is an oil-like serum designed to continuously support your skin with antioxidants and leave your skin looking brighter. By using a self-regenerating molecule that mimics the effects of two powerful antioxidants found naturally in your skin, this high-strength serum actively protects your skin from the effects of damage caused by environmental stressors.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.

My HG
This, together with Ascorbyl Tetraisopalmitate, is my holy grail. It gives me the brightest skin of my life, consistently. I find it rather unpleasant to use (I try to use as little as possible, but my skin will still be sticky forever afterward - going outside does seem to help though), and yet I'm on my umpteenth bottle. There have been times where I didn't use EUK and just relied on ATIP, but I keep coming back and am on my umpteenth bottle. I originally got it for extra support under my sunscreen, and it's given me that and so much more. I struggle with body image, and seeing my skin so clear and glowy in the mirror makes it better.

Reco’d by Brandon - makes skin look flawless
I originally purchased this upon the reco of Brandon Truaxe in a popular Facebook group for Deciem fans. He said it was his fav antioxidant serum out of all the Deciem product lines. It’s amazing. I accidentally spilled it when I’d first bought it and perhaps foolishly, tried to wipe up as much as possible and put it all on my face. The next day, all the uneven redness was gone from my face and it was like my face was airbrushed. I got many compliments. Now I use it periodically, basically the day before and morning of an event or in person meeting. I use it liberally, like maybe a full dropper full. I wear zero foundation and get lots of compliments on my 42 yo skin which I use only Deciem products + RetinA Micro on. Thank you, Brandon! 🦋 You always gave the best most sincere advice. Pls don’t ever discontinue this product, Team Deciem. It deserves way more love which is why I’m leaving my first ever review!
