Made to work together
Cleanse and apply the Lotion P50 selected for your Skin Instant before the mask. Apply Masque Vivant to the whole face or only to the oiliest zones, pairing it with a more hydrating mask elsewhere if needed. After rinsing, follow with the serums and cream appropriate for your Skin Instant, and sunscreen in the morning.

A few drops of Complexe Iribiol mixed into Masque Vivant create a more targeted version of the mask for very oily, blemish-prone Skin Instants.
Worth knowing
A closer look at your skin, your routine and what goes into the formula.
Biologique Recherche Masque Vivant is a cult-status rebalancing face mask formulated with a remarkably high concentration of Yeast Extract, its first ingredient, alongside purifying clays, Cucumber Extract, Witch Hazel, Vinegar and Lactic Acid. It helps rebalance skin experiencing excess sebum, visible pores and recurring imperfections.
Together, the formula approaches oil-prone skin from several directions at once: absorbing excess surface sebum, supporting purification, refining texture and helping restore a more balanced-looking complexion. It is less a simple clay mask than a Biologique Recherche purifying mask with clay in it.
The goal is not to leave the face feeling stripped: skin needs sebum, and the concern is excess. After 15 minutes, skin feels exceptionally clean and refreshed, excess shine appears reduced, texture looks more refined and pores appear less noticeable. Its distinctive brown texture and unmistakable scent are part of the experience.
We don't choose Masque Vivant because skincare needs to feel luxurious; we choose it because congested, oil-prone skin sometimes needs a very good reset. We love multi-masking with it: concentrate it on the T-zone where oil and congestion show most, and use a more hydrating mask on comfortable cheeks. And if skin is going through significant sensitivity, dryness or barrier discomfort, we don't push through with it. Your Skin Instant always wins.
Skin prone to excess oil and blemishes
Combination skin doesn't read instruction manuals: apply Masque Vivant only where oil and congestion show, and a more hydrating mask everywhere else.
Yeast Extract, Water (Aqua), Propylene Glycol, Bentonite, Kaolin, Alcohol Denat., Cucumis Sativus (Cucumber) Fruit Extract, Glycerin, Vinegar (Acetum), Lactic Acid, Hamamelis Virginiana (Witch Hazel) Bark/Leaf/Twig Extract, Hypericum Perforatum Flower/Leaf/Stem Extract, Acacia Senegal Gum, Xanthan Gum, Sodium Bisulfite.
The current official INCI lists Yeast Extract as the first ingredient. Some older descriptions call it "live yeast", but Biologique Recherche's current ingredient list identifies it as Yeast Extract.
Its distinctive scent comes from its highly concentrated formula, including Yeast Extract, Vinegar and botanical ingredients. It is not designed to smell like perfume.
It depends on your current Skin Instant. The formula contains purifying clays, Alcohol Denat. and Lactic Acid, so highly reactive or compromised skin may need another mask. Ask us before introducing it.
It depends on your current Skin Instant. Oilier, more congested skin may tolerate it more often, while combination or reactive skin may benefit from less frequent or localized use.
No. After 15 minutes, emulsify with cold water and remove thoroughly; it does not need to become dry or cracked.
Yes, a few drops of Complexe Iribiol are commonly added for oily, blemish-prone Skin Instants. This more intensive version is not the place to start if your skin is reactive or new to active skincare.
