Made to work together
Cleanse, apply the Lotion P50 selected for your Skin Instant, then Oligo-Protéines Marines. If you layer several serums, apply the more fluid ones first. Depending on your Skin Instant, Crème Contour des Yeux VIP O₂ can complement it around the eyes before you finish with your moisturizer, and sunscreen in the morning.

Worth knowing
A closer look at your skin, your routine and what goes into the formula.
Biologique Recherche Oligo-Protéines Marines is an energizing and revitalizing serum designed for dull-looking skin and visible dark circles.
Formulated with a Complex of Marine Oligo Proteins, it helps reduce the bluish appearance of dark circles while restoring luminosity to tired-looking skin. The complexion appears fresher, more rested and revitalized, which makes it particularly interesting when fatigue seems to show on both the face and around the eyes.
It is a face serum applied over the face, neck and décolleté, with a targeted action on the look of dark circles. Unlike an eye product focused primarily on puffiness, Oligo-Protéines Marines is especially suited to bluish-looking dark circles and loss of radiance.
We think about Oligo-Protéines Marines when someone tells us they always look tired, that their under-eyes look blue or purple, or that their skin has lost its brightness. The important distinction is darkness versus puffiness: for swelling or bags, Liposmose is usually the more targeted conversation, and for distinctly brown darkness we want to understand whether pigmentation is involved. That is why we prefer to look at the eye contour rather than recommend the same eye product to everyone.
Dull-looking skin, bluish dark circles
Look under your eyes: if you mainly see a blue or purple shadow, this is your serum; if you see swelling first, ask us about Liposmose.

No. It is an energizing anti-dark-circle face serum applied over the face, neck and décolleté, with a targeted action on the look of dark circles.
Biologique Recherche specifically highlights its action on bluish-looking dark circles. Brown-looking dark circles call for a different, pigmentation-focused approach.
Puffiness and bags are not its primary target. If they are your main concern, Liposmose is the more targeted Biologique Recherche serum.
Yes, depending on your Skin Instant. Oligo-Protéines Marines acts as the targeted serum, while the eye cream brings hydration and broader support for radiance and eye-contour skin quality.
After cleansing and the Lotion P50 selected for your Skin Instant. If you layer several serums, apply the more fluid formulas first, then your moisturizer.
No. Its ingredient list includes aromatic compounds such as cinnamal and farnesol, so check the full list if you are sensitive to fragrance ingredients.
