The NIVEA Luminous630 Advanced Anti-Stretch Mark Body Treatment Serum features a unique formula containing the innovative LUMINOUS630® ingredient, which helps to balance skin tone and effectively diminish the visibility of stretch marks resulting from pregnancy, hormonal shifts, and weight fluctuations. This serum not only enhances skin softness around stretch marks but also delivers intense hydration for up to 48 hours and can address older marks as well. After just one day of application, the patented LUMINOUS630® component begins to work at a cellular level, promoting a more uniform skin tone. Users can expect to see the first noticeable improvements in just 2 weeks, with a marked reduction in stretch marks after 4 weeks. Consistent application yields even better outcomes. *Clinically tested for skin compatibility.
