    EUK 134 0.1% Serum

    Unit price  per 

    Starring an exceptionally rare self-regenerating antioxidant, The Ordinary’s EUK 134 0.1% provides age-defying power offered by very few other products on the market. The pleasingly wallet-friendly price tag does not reflect its extremely high potency – while EUK 134 itself is very costly, the most common concentration for any formulation is below 0.05%, so The Ordinary’s 0.1% is impressively high, unmatched by any other product on the market.* Free from water, silicones, oils and alcohol (all of which can impair the stability of antioxidants)

    EUK 134 0.1% consists of an exceptionally rare self-generating molecule that neutralises free radicals, therefore preventing the inhibition of collagen and elastin production (which keeps skin plumper and more youthful). This potent product can also be mixed with others, such as The Ordinary’s {Natural Moisturizing Factors + HA}, for a strong antioxidant boost; however, it should not be used immediately with strong acids, as they will compromise its beneficial effects.

    Why We Like It

    The pocket money price tag of this formula belies its incredible potency – in fact, EUK 134 is one of the strongest antioxidants available, which can regenerate itself to offer round-the-clock defense from free radical damage. Neglected by the mass market, The Ordinary is bringing this innovative ingredient straight to your radiance regime – at an ultra-high (0.1%) concentration to maximise the age-defying effects.


    Apply alone or after water-based serums, before oils or heavier creams. You can also mix with other treatments to enhance their antioxidant capacity significantly.

    Do not use with highly acidic formulations such as suspensions of ascorbic acid. Use only as directed on unbroken skin.
