The Ordinary EUK 134 0.1% is a highly stable, water-free antioxidant serum designed to protect your skin from environmental stress and premature aging. Powered by EUK-134—a powerful molecule that mimics the natural antioxidant enzymes found in skin—this formula works to neutralize free radicals, reduce oxidative damage, and support a brighter, healthier-looking complexion.

Unlike many antioxidant formulas, EUK-134 is self-regenerating, meaning it continues to work long after application, offering long-lasting protection. With a silky, oil-like texture (but without actual oils), it absorbs easily and layers well with most skincare products.

Ideal for anyone seeking advanced antioxidant support without irritation, this serum is perfect for defending skin against pollution, stress, and UV-related damage. However, it should not be used in combination with strong acids (like vitamin C) as they can destabilize the formula.
