EUK 134™ 0.1%, is an oil-like serum designed to support your skin with antioxidants to target dull and lacklustre skin tone. By using a self-regenerating molecule that mimics the effects of two powerful antioxidants found naturally in your skin, this high-strength serum helps promote even tone, hydration, and skin radiance. This formulation supports the skin's defense against the visible effects of damage caused by environmental stressors while being suitable for all skin types including sensitive skin.
The low price of this formula does not reflect EUK-134™'s extremely high potency. Our formula uses EUK-134™ at an extremely high 0.1% concentration.
