Eucerin Even Pigment Perfector Dual Serum 30mlis a dual-action serum that both reduces dark spots and prevents their re-appearance. It contains thiamidol, an active ingredient that acts at the root cause of hyperpigmentation by reducing melanin production. Clinical and dermatological studies show thiamidol is effective in both reducing dark spots and preventing their re-appearance. Because of this, thiamidol is the perfect ally for a radiant and even complexion. This dual serum also contains concentrated hyaluronic acid, an effective moisturizing ingredient that helps the skin attract and retain moisture.

In a clinical study, 100% of volunteers reported their skin was more radiant and 94% found it more even, 91% noticed a reduction in the appearance of dark spots, and 88% remarked that the product was effective in fighting dark spots. These results were visible after just two weeks, and improved with regular use.
