Masque PIGM 400

BRIGHTENING + ANTI-DARK SPOT SHEET MASK

This is not your average sheet mask.

Biologique Recherche Masque PIGM 400 is a single-use brightening treatment mask created for skin experiencing uneven pigmentation, visible dark spots and loss of radiance.

Saturated in a concentrated blend of brightening and antioxidant ingredients, its ultra-soft Lyocell fabric hugs the contours of the face to keep the formula in close contact with the skin throughout the treatment.

After just 15 minutes, the complexion appears fresher, more luminous and more even.

Masque PIGM 400 is particularly beautiful when you want immediate radiance today while supporting a longer-term pigmentation-focused routine for tomorrow.

Skin Instant:

Recommended for pigmented and dull Skin Instants.

We particularly think about Masque PIGM 400 when skin is experiencing:

• Visible dark spots
• Uneven-looking pigmentation
• Post-blemish discoloration
• A dull or lacklustre complexion
• Uneven-looking skin tone
• Reduced radiance
• Skin that needs an immediate luminosity boost
• A pigmentation-focused routine that could benefit from an intensive treatment step

The Sheet Mask That Actually Feels Like a Treatment

Sheet masks are everywhere.

What makes Masque PIGM 400 interesting is not simply that it comes in a sachet.

It's the delivery system.

Biologique Recherche uses Lyocell, an ultra-soft cellulose fibre derived from wood.

The material is:

• Extremely soft
• Highly absorbent
• Biodegradable
• Able to closely follow the contours of the face

Biologique Recherche reports that Lyocell can absorb approximately 50% more than cotton, allowing it to hold a high concentration of the treatment formula against the skin.

That means the sheet isn't just packaging for the serum.

It is part of the treatment.

Why Pigmentation Needs More Than “Brightening”

“Brightening” is one of those skincare words that can mean almost anything.

When we talk about Masque PIGM 400, our goal is not to make your natural skin tone lighter.

We are talking about helping improve the contrast created by uneven pigmentation.

That may look like:

• Brown spots
• Post-blemish marks
• Uneven patches
• Sun-associated discoloration
• Areas that appear darker than the surrounding complexion

Masque PIGM 400 combines brightening ingredients with antioxidant support to help the complexion appear more uniform and luminous.

The goal is not lighter skin.

The goal is:

your skin tone — more even.

Immediate Glow vs. Long-Term Pigmentation Care

This distinction matters.

Masque PIGM 400 can give the complexion an immediate visible radiance boost after one treatment.

But pigmentation itself is rarely a one-mask conversation.

Long-term improvement generally requires consistency across the routine, including:

• Appropriate exfoliation
• Targeted pigmentation treatments
• Antioxidant support
• Daily sun protection
• Avoiding unnecessary inflammation

That is why we see Masque PIGM 400 as an intensive treatment within a pigmentation routine, rather than pretending one sheet mask can erase every dark spot.

How to Use:

• Cleanse and thoroughly dry the face and neck.
• Open the sachet and unfold Masque PIGM 400 completely.
• Remove the protective polyester film.
• Apply the Lyocell mask directly to the skin.
• Using your fingertips, gently smooth the material over the contours of the face so it adheres closely.
• Leave on for 15 minutes.
• Remove and discard the mask.
• Do not rinse.
• Massage the remaining product into the face and neck using gentle smoothing movements from the centre outward, beginning at the neck and working upward.
• Single-use product.

For external use only.

Loshen & Crem’s Recommendation:

Masque PIGM 400 is what we reach for when someone tells us:

• “I want my skin to look amazing tonight.”
• “My pigmentation routine is working, but I want more radiance.”
• “My complexion looks uneven and tired.”
• “Every blemish leaves a brown mark.”
• “I have an event and want something that actually makes a visible difference.”
• “I love sheet masks, but I want one that feels more treatment-focused.”

This is our event mask for the pigmentation-minded client.

You get the immediate satisfaction of a fresher, more luminous complexion, while the formula still makes sense within a routine focused on uneven pigmentation.

And unlike a clay or cream mask, there is very little technique involved.

Apply.

Lie down.

Try not to answer emails.

Fifteen minutes later, continue your routine.

The Night-Before-An-Event Ritual

We particularly love Masque PIGM 400 the evening before an event.

1. Cleanse thoroughly.
2. Apply the appropriate Lotion P50 if your Skin Instant comfortably tolerates it.
3. Apply Masque PIGM 400 for 15 minutes.
4. Remove the sheet and massage in the remaining formula.
5. Follow with your appropriate serum and cream.
6. Finish your evening and leave the experimenting to another night.

The night before an event is not the time for aggressive exfoliation, picking at blemishes or introducing six new actives.

The goal is:

calm + even + luminous.

Masque PIGM 400 vs. Lotion P50 PIGM 400

They belong to the same pigmentation conversation but occupy completely different stages of the routine.

Lotion P50 PIGM 400 is the regular exfoliating preparation step.

It focuses on:

• Surface-cell renewal
• Exfoliation
• Uneven pigmentation
• Brightness
• Preparing the epidermis for treatment

Masque PIGM 400 is the intensive treatment mask.

It focuses on:

• Immediate radiance
• Visible luminosity
• Uneven-looking tone
• An intensive pigmentation-focused treatment

Think:

• P50 PIGM 400 → prepare + exfoliate + brighten
• Masque PIGM 400 → saturate + perfect + illuminate

Masque PIGM 400 vs. Sérum PIGM 400

This might be the most useful comparison.

Masque PIGM 400 is occasional intensive care.

Sérum PIGM 400 is ongoing targeted treatment.

Choose Masque PIGM 400 when you want:

• An immediate radiance boost
• An occasional pigmentation treatment
• A pre-event mask
• A concentrated 15-minute treatment

Choose Sérum PIGM 400 when you want:

• Daily pigmentation support
• Ongoing treatment of visible dark spots
• A more even-looking complexion over time
• A dedicated serum step within your routine

In the simplest terms:

• Masque PIGM 400 = intensive treatment
• Sérum PIGM 400 = daily treatment

For significant pigmentation concerns, they can complement one another beautifully.

Masque PIGM 400 vs. Iso-Placenta

This depends entirely on why the mark is there.

Choose Masque PIGM 400 when the main conversation is:

• Brown pigmentation
• Dark spots
• Uneven tone
• Dullness
• Radiance

Choose Iso-Placenta when the concern is more specifically:

• Marks following blemishes
• Redness remaining after breakouts
• Post-acne skin
• Uneven microrelief
• Skin restoration after imperfections

A post-blemish mark can contain both pigmentation and redness, which is why we don't automatically treat every “acne scar” with the same product.

What Is Lyocell?

Lyocell is a cellulose fibre created from wood.

Biologique Recherche uses it for Masque PIGM 400 because it is exceptionally soft and absorbent while conforming closely to facial contours.

The cellulose used for the mask comes from sustainably managed forests unsuitable for agriculture.

The material itself is biodegradable, and the manufacturing process uses a recyclable solvent to create the fibres.

From a skincare perspective, the important part is simple:

the mask can hold a lot of formula and keep it in close contact with your skin for those 15 minutes.

Ingredients:

• Ascorbyl Glucoside: A stabilized Vitamin C derivative incorporated into the formula's brightening and antioxidant complex.
• Palmaria Palmata Extract: Red algae extract included within the pigmentation-focused formulation.
• Sucrose Dilaurate: Incorporated into the brightening complex alongside targeted botanical ingredients.
• Pisum Sativum (Pea) Extract: Pea extract included within the formula's anti-dark-spot complex.
• Hydrolyzed Opuntia Ficus-Indica Flower Extract: Prickly pear flower-derived extract incorporated into the current formula.
• Yeast Extract: Helps support overall skin conditioning within the treatment essence.
• Glycerin: A humectant that helps maintain hydration and skin comfort.
• Pentylene Glycol: Helps support moisture and the lightweight serum-like texture of the formula.

It helps instantly improve visible radiance while supporting a more even-looking complexion.

Is Masque PIGM 400 a sheet mask?

Yes — but it is made from Lyocell, an exceptionally soft and absorbent cellulose fibre.

Biologique Recherche selected the material because it conforms closely to the facial contours and can hold a high concentration of treatment formula.

How long do I leave Masque PIGM 400 on?

The current Biologique Recherche directions specify 15 minutes.

Older instructions often stated 20 minutes, but the current manufacturer protocol is 15.

Do I wash my face after Masque PIGM 400?

Can I reuse Masque PIGM 400?

No.

It is a single-use treatment mask.

Does Masque PIGM 400 help dark spots?

Biologique Recherche positions Masque PIGM 400 specifically as an anti-dark-spot, brightening and perfecting mask for pigmented and dull Skin Instants.

For persistent pigmentation, we view the mask as one component of a broader pigmentation-focused routine rather than a stand-alone solution.

Does Masque PIGM 400 help hyperpigmentation?

It is designed specifically for uneven pigmentation and visible dark spots.

Consistency across your overall routine — and especially sun protection — remains important when pigmentation is a concern.

Does Masque PIGM 400 help post-acne marks?

It may be particularly useful when previous blemishes leave brown pigmentation behind.

If the concern is primarily redness or the skin's recovery following blemishes, Iso-Placenta may be the more targeted conversation.

Does Masque PIGM 400 lighten the skin?

We would not describe it as a skin-lightening product.

Its purpose is to improve the appearance of uneven pigmentation and restore radiance so your natural complexion appears more uniform.

Does Masque PIGM 400 contain Vitamin C?

Yes.

The current formula contains Ascorbyl Glucoside, a stabilized Vitamin C derivative.

Is Masque PIGM 400 hydrating?

The formula contains humectants including Glycerin and Pentylene Glycol, so it provides some moisture support.

Its primary purpose, however, is brightening, anti-dark-spot and perfecting, rather than intensive hydration.

If dehydration is your main concern, another Biologique Recherche mask may make more sense.

Can sensitive skin use Masque PIGM 400?

The current manufacturer recommendation is based on pigmented and dull Skin Instants rather than sensitivity.

If your skin is highly reactive or your barrier is compromised, contact us before introducing a pigmentation-focused treatment.

Is Masque PIGM 400 good before an event?

This is one of our favourite ways to use it.

Because Biologique Recherche describes its radiance effect as immediate, Masque PIGM 400 makes an excellent treatment when you want your complexion to look brighter and more even before an event.

Should I use Masque PIGM 400 before or after Lotion P50?

Within a typical Biologique Recherche routine, cleansing and your appropriate Lotion P50 prepare the skin before the mask stage.

Follow Masque PIGM 400 with the targeted serums and cream selected for your Skin Instant.

What is the difference between Masque PIGM 400 and Sérum PIGM 400?
