About the product
Sérum PIGM 400 is the heart of Biologique Recherche's pigmentation line. It works on spots that are already visible, whether from sun or the marks left by inflammation, while helping prevent new ones, with a complex that acts at different points of pigment formation.
Apply a few drops after Lotion P50 PIGM 400, morning and evening. The texture is fluid and leaves no residue. Results arrive over the weeks: spots lose intensity, the tone looks more even and the face brighter.
It works best as part of a full routine with sun protection every morning, which is what stops the work from being undone.
