Melanin is a natural pigment that gives color to skin. Exposure to sunlight, hormonal influences and aging can cause an increase in melanin production and trigger hyperpigmentation. Hyperpigmentation appears as dark patches and age spots also known as sun spots that make skin look uneven. Eucerin AntiPigment Day SPF 30 contains Thiamidol, an effective and patented ingredient that acts at the root cause of hyperpigmentation by reducing melanin production. It is clinically and dermatologically proven to reduce dark spots and prevent their reappearance. First results are visible after two weeks and improve continuously with regular use. With UVA and UVB filters SPF 30 the moisturising day cream offers effective protection from the sun and reduces the chances of skin developing suninduced pigment spots. Skin appears even and radiant.
