Eucerin Even Pigment Perfector Dual Serum is a specialized skincare treatment designed to address uneven skin tone and hyperpigmentation. This 30ml dual-phase serum contains Thiamidol, a patented ingredient that helps reduce dark spots and prevent their reappearance while evening out skin tone. The dual-phase formula combines two serums in one product for enhanced efficacy. The first phase contains the active ingredient Thiamidol that works at the root cause of hyperpigmentation by reducing melanin production. The second phase provides hydration and helps improve the overall appearance of the skin. For best results, the serum should be applied morning and evening to cleansed skin before moisturizer. The product comes in an elegant pump bottle that keeps the formula fresh and enables precise dispensing.
