What the brand claims
In the brand’s own words, quoted as written.
“EUK 134 0.1% is a lightweight, oil-like serum formulated to help improve skin tone and radiance by supporting the skin’s natural defenses against environmental stressors. It features EUK-134™, a self-regenerating molecule that mimics two naturally occurring antioxidants in the skin, delivered at a high 0.1% concentration to promote a more even, luminous complexion. Suitable for all skin types, including sensitive skin, it provides antioxidant protection without irritation.”
