Product details
A closer look.
Biologique Recherche Sérum PIGM 400 is an illuminating face serum for skin that looks dull, with visible dark spots and uneven-looking pigmentation. It helps reduce the appearance of pigmentation marks and helps even the look of skin tone. With daily use, the complexion looks more even, luminous and visibly radiant. Its brightening complex is built around a wasabi root ferment with watercress sprout extract and soy isoflavones, alongside plum and marine extracts and antioxidant ingredients that help protect skin from environmental stressors. Sérum PIGM 400 is the serum step of the PIGM 400 face routine, between Lotion P50 PIGM 400 and Crème PIGM 400.
Why you’ll love it.
Dark spots fade gradually, and we love that Sérum PIGM 400 fits into a clear, complete routine with Lotion P50 PIGM 400 and Crème PIGM 400. It brings the targeted brightening step while the rest of the routine keeps things simple. We always remind clients that consistency and daily sunscreen matter as much as the products themselves. Used that way, the complexion looks more even and luminous over time.
