Melanin is a natural pigment that gives color to the 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 Even Pigment Perfector Dual Serum brings together two serums that work in different ways:

Thiamidol: an effective and patented ingredient that acts at the root cause of hyperpigmentation is clinically proven to reduce hyperpigmentation, preventing its re-appearance with regular usage

Concentrated Hyaluronic Acid: one of the skin’s most effective moisturizing substances that helps skin to attract and retain moisture

The light emulsion is clinically and dermatologically proven to reduce dark spots and prevent their re-appearance while renewing the skin’s look. The first results are visible after two weeks and improve continuously with regular use. Skin is smooth and looks renewed, even, and radiant.

Clinical and dermatological studies prove very good efficacy and skin tolerability.

Application of Eucerin Anti Pigment Dual Serum and Even Pigment Perfector Day SPF30 twice a day for 8 weeks.
