About the product
Serum PIGM 400 is the serum of the PIGM 400 range, the one Biologique Recherche dedicates to dark spots. It is formulated for three things: helping to prevent new spots from appearing, fading existing ones and evening and brightening the tone overall.
Its actives combine watercress sprout extract and soy genistein with peptides, plum pulp extract and marine extracts, among them the seaweed Ascophyllum nodosum, which helps regulate melanin synthesis. Press it in after Lotion P50 PIGM 400, morning and evening, always with sun protection by day. It is water-based and absorbs in seconds. Over the weeks, spots look lighter and tone more even.
The 8 ml size lets you treat specific areas.
