The ingredients behind this formula—and what they bring to your skin.
Caulerpa Lentillifera Extract
Green Caviar extract at the centre of the formula's toning and smoothing concept.
Palmitoyl Tripeptide-1
A peptide incorporated into the mask's anti-wrinkle and skin-conditioning complex.
Hydrolyzed Rice Bran Protein
A protein-derived ingredient used in the smoothing and toning formulation.
Ingredient imagery is illustrative. Explore the full ingredient list below.
Made to work together
Cleanse thoroughly and apply the Lotion P50 selected for your Skin Instant before the mask. After 15 minutes, massage in the remaining serum, then follow with your appropriate serum and moisturizer and allow everything to settle before makeup. Where wrinkles and reduced density are recurring concerns, Collagène Originel makes excellent sense as the ongoing serum in the same routine.

Your routine
Caviar Vert gives an occasional, immediate smoothing and tautening effect, while Collagène Originel is the ongoing serum for wrinkles and density; where those concerns are recurring, the two make excellent sense in the same routine.
Worth knowing
A closer look at your skin, your routine and what goes into the formula.
Fifteen minutes. One sheet. A visibly smoother-looking face. Biologique Recherche Masque Caviar Vert is a single-use biocellulose mask created for skin showing visible wrinkles, reduced tone and changes in facial firmness.
It is saturated with a concentrated anti-wrinkle serum built around Green Caviar, a marine algae (Caulerpa Lentillifera) with tiny pearl-like structures, and what Biologique Recherche calls its Collagen Segment. Together, they help tone the epidermis and improve the visible appearance of skin structure, visibly plumping fine lines, smoothing the complexion and creating an immediate tautening effect.
Its ultra-fine biocellulose support behaves almost like a second layer of skin, following facial contours closely so the serum stays in intimate contact with the complexion for the full 15 minutes. It is very different from a conventional loose-fitting sheet mask.
When removed, wrinkles appear softer, facial features look more refined and the skin has a beautifully smooth, supported finish. The tautening effect is cosmetic and immediate, not a permanent lift.
Masque Caviar Vert is not our thirst mask, our pigmentation mask or our purifying mask. It is our 'make everything look a little more polished and supported' mask, for the client who doesn't need another hydration mask but wants to look pulled together. We particularly love it before an event, a dinner or photos, when you want a visible result without adding another aggressive active to your routine.
Visible wrinkles, reduced firmness
The night before an event, keep it elegant: no new peel, no aggressive extractions, just Caviar Vert followed by your usual serum and cream.

No. After removing and discarding the mask, massage the remaining serum into the skin using gentle smoothing movements.
No. It is a single-use mask.
No. 'Green Caviar' refers to Caulerpa Lentillifera algae, named for its small pearl-like appearance. It is not fish roe.
Biologique Recherche describes the mask as formulated around Green Caviar and a Collagen Segment. The current INCI contains Palmitoyl Tripeptide-1 along with protein- and algae-derived ingredients.
It provides a visible tautening effect, helping facial features look tighter and wrinkles smoother. The result is cosmetic and immediate rather than a permanent structural lift.
Masque Caviar Vert is an occasional, intensive biocellulose mask for an immediate smoothing and tautening effect. Collagène Originel is an ongoing serum focused on wrinkles, density, plumpness and structural skin support.
