Lait Dermo-S

HIGH-TOLERANCE SOOTHING CLEANSING MILK

Biologique Recherche Lait Dermo-S is a high-tolerance soothing cleansing milk created specifically for fragile, reactive and easily uncomfortable Skin Instants.

Its gentle formula removes makeup, sunscreen and daily impurities while helping preserve skin comfort during one of the most important — and often overlooked — steps of a sensitive-skin routine: cleansing.

Rather than leaving vulnerable skin feeling tight or stripped, Lait Dermo-S helps soothe visible redness and irritation associated with external stress while supporting hydration and the skin's protective barrier.

After cleansing, skin feels clean, soft, calm and comfortable.

Skin Instant:

Recommended for fragile Skin Instants.

Particularly suited to skin experiencing:

• Increased sensitivity or reactivity
• Redness associated with external stress
• Tightness after cleansing
• Tingling or feelings of discomfort
• A weakened-feeling skin barrier
• Dehydration associated with increased water loss
• Skin that reacts easily to environmental changes
• Difficulty tolerating traditional cleansers

Benefits:

• Gently removes makeup and daily impurities
• Provides high-tolerance cleansing for fragile skin
• Helps soothe visible redness and irritation associated with external stress
• Relieves feelings of tightness after cleansing
• Supports the skin's protective barrier
• Helps maintain hydration during cleansing
• Leaves skin feeling soft and comfortable
• Respects vulnerable Skin Instants without aggressive cleansing

What Does “Fragile Skin” Actually Mean?

Sensitive skin is often treated like one universal skin type, but Biologique Recherche uses the term fragile Skin Instant for a reason.

Fragile skin may have:

• Increased reactivity
• Reduced barrier function
• Greater sensitivity to environmental stress
• Increased moisture loss
• A lower tolerance for certain skincare products

When water escapes from the skin too quickly, its natural protective function can become less effective.

This can make it easier for external irritants to affect the skin and may contribute to sensations such as:

• Tightness
• Tingling
• Itching
• Redness
• General discomfort

This is why cleansing matters so much.

When the skin barrier already feels vulnerable, using an overly aggressive cleanser can make the entire routine harder for the skin to tolerate.

Lait Dermo-S is designed to cleanse without creating another source of stress.

Why Sensitive Skin Shouldn't Feel Squeaky Clean

That very tight, squeaky-clean sensation after washing your face is not necessarily a sign of a better cleanse.

For fragile Skin Instants, it can be exactly what we want to avoid.

A cleanser should remove:

• Makeup
• Sunscreen
• Excess surface residue
• Sweat
• Daily environmental impurities

without leaving the skin feeling as though everything protective has been removed along with them.

Lait Dermo-S prioritizes tolerance and comfort, allowing cleansing to support the routine rather than becoming something the skin has to recover from.

How to Use:

1. Apply a small amount of Lait Dermo-S over the entire face, neck and décolleté.
2. Emulsify using light smoothing movements, working from the inside outward and from the décolleté upward toward the face.
3. Remove using wet cotton pads.
4. Repeat until makeup and impurities have been completely removed.

For external use only.

Loshen & Crem’s Recommendation:

Lait Dermo-S is the cleanser we think about when a client tells us:

• “Everything makes my skin feel tight.”
• “My face becomes red after cleansing.”
• “My skin suddenly reacts to products it used to tolerate.”
• “I need to simplify everything.”
• “Even cleansing has started to feel uncomfortable.”

That last one tells us a lot.

When skin is fragile or reactive, our instinct isn't to add five more corrective products.

Often, the smarter place to start is making the basic steps of the routine more tolerable.

And cleansing is step one.

Lait Dermo-S is beautifully simple: remove what needs to come off the skin while leaving the skin itself as comfortable as possible.

If your Skin Instant is going through a particularly reactive period, this is often the kind of cleanser we look toward before worrying about doing more.

Lait Dermo-S vs. Lait E.V.

These two cleansing milks are both comforting, but they address different priorities.

Choose Lait Dermo-S when the main concerns are:

• Fragility
• Reactivity
• Redness
• Tingling
• Irritation
• Tightness associated with sensitivity
• A compromised-feeling barrier

Choose Lait E.V. when the main concerns are:

• Dryness
• Lipid deficiency
• Dehydration
• Lack of nourishment
• Mature skin becoming increasingly dry

In the simplest terms:

• Lait Dermo-S = soothe + high tolerance
• Lait E.V. = nourish + replenish lipids

Dry skin can also be sensitive, of course.

When both are present, your current Skin Instant — rather than your historical “skin type” — should guide the choice.

Lait Dermo-S vs. Lait S.R.

These two cleansers sit at almost opposite ends of the Skin Instant conversation.

Choose Lait Dermo-S when your skin is:

• Fragile
• Reactive
• Easily irritated
• Red
• Uncomfortable after cleansing

Choose Lait S.R. when your skin is primarily:

• Combination
• Seborrheic
• Oil-prone
• Congested
• Shiny through the T-zone

Think:

• Lait Dermo-S → calm + comfort + barrier support
• Lait S.R. → purify + rebalance excess sebum

If your skin is oily and reactive, don't automatically choose the more purifying cleanser. We would rather assess what the skin can comfortably tolerate at that moment.

Lait Dermo-S + Emulsion Gel Biosensible

For a Skin Instant where sensitivity continues beyond the cleansing step, Emulsion Gel Biosensible can provide complementary soothing and moisturizing support.

Their roles are different:

• Lait Dermo-S → high-tolerance cleansing
• Emulsion Gel Biosensible → soothing + moisturizing treatment

The goal is not to overwhelm reactive skin with products.

It's to build a routine where each step has a reason to be there.

Ingredients:

• Niacinamide: Vitamin B3 helps support the skin barrier and overall skin comfort.
• Panthenol: Pro-vitamin B5 helps support hydration and soothe uncomfortable-feeling skin.
• Salvia Miltiorrhiza Root Extract: Red sage root extract incorporated into the formula's soothing complex.
• Opuntia Ficus-Indica Stem Extract: Prickly pear cactus extract helps support hydration and skin comfort.
• Glycerin: A humectant that helps attract and maintain water within the skin.
• Caprylic/Capric Triglyceride: A skin-conditioning emollient that supports a soft, comfortable finish.
• Coco-Caprylate/Caprate: A lightweight emollient that helps dissolve makeup and impurities while maintaining a comfortable skin feel.

Frequently Asked Questions

What is Biologique Recherche Lait Dermo-S?

Lait Dermo-S is a high-tolerance soothing and moisturizing cleansing milk from Biologique Recherche designed specifically for fragile Skin Instants.

It gently removes makeup and impurities while helping calm visible redness, irritation and feelings of tightness associated with external stress.

Is Lait Dermo-S for sensitive skin?

Yes. Biologique Recherche specifically recommends Lait Dermo-S for fragile Skin Instants.

This can include skin experiencing heightened reactivity, redness, tightness, tingling or reduced tolerance to external stressors.

Is Lait Dermo-S good for a damaged skin barrier?

Biologique Recherche explains that fragile Skin Instants can have altered barrier function and increased water loss.

Lait Dermo-S is designed to cleanse these vulnerable Skin Instants gently while supporting comfort and hydration.

We prefer “barrier-supportive cleansing” rather than promising that a cleanser alone can completely repair a compromised barrier.

Can Lait Dermo-S help redness?

Its soothing action is specifically designed to help calm irritation and redness associated with external stress.

Persistent, unexplained or severe redness may have other causes and should be assessed appropriately.

Is Lait Dermo-S good for reactive skin?

Yes. Its high-tolerance positioning makes it particularly relevant when the skin is reacting more easily than usual or has difficulty tolerating traditional cleansers.

Is Lait Dermo-S good for dry skin?

It can be comfortable for dry-feeling skin, particularly when sensitivity is also present.

If lipid deficiency and persistent dryness are the primary concerns rather than reactivity, Lait E.V. may be the more targeted choice.

Is Lait Dermo-S good for oily sensitive skin?

Potentially, yes.

Skin can produce excess sebum while simultaneously being fragile or reactive. In that situation, we would prioritize what the skin can tolerate rather than automatically choosing the strongest purifying cleanser.

Does Lait Dermo-S remove makeup?

Yes. Biologique Recherche specifically describes Lait Dermo-S as a high-tolerance soothing makeup remover.

Repeat the cleansing process until makeup and impurities have been removed.

Can Lait Dermo-S remove sunscreen?

Yes. As a cleansing milk, it can help remove sunscreen and daily residue.

For heavier or more resistant makeup and sunscreen, repeating the cleansing process may be appropriate.

Do I need to double cleanse with Lait Dermo-S?

Biologique Recherche recommends repeating the cleansing process until impurities have been completely removed.

For sensitive Skin Instants, this may mean performing two gentle passes with Lait Dermo-S rather than introducing a stronger second cleanser.

Should I rinse Lait Dermo-S with water?

Biologique Recherche currently recommends removing the cleanser using wet cotton pads.

Does Lait Dermo-S contain niacinamide?

Yes. Niacinamide is one of the ingredients in the current Lait Dermo-S formula.

What is the difference between Lait Dermo-S and Lait E.V.?

Lait Dermo-S is primarily designed for fragile and reactive Skin Instants and emphasizes high-tolerance, soothing cleansing.

Lait E.V. is primarily designed for alipidic, dehydrated and mature Skin Instants and focuses more heavily on nourishment and lipid replenishment.

What is the difference between Lait Dermo-S and Lait S.R.?

Lait Dermo-S is a soothing high-tolerance cleanser for fragile Skin Instants.

Lait S.R. is a purifying and rebalancing cleansing milk for combination and seborrheic Skin Instants experiencing excess sebum.

Can I use Lait Dermo-S every day?

Yes, when appropriate for your Skin Instant.

It is designed as a gentle cleansing step and may be used as part of a daily Biologique Recherche routine.

What should I use after Lait Dermo-S?

The next step depends on the condition of your skin.

Within the Biologique Recherche methodology, cleansing is followed by the appropriate lotion and then serums, creams and finishing products selected according to the current Skin Instant.

When skin is particularly fragile or reactive, the goal may be to keep that routine intentionally simple.

Who should use Biologique Recherche Lait Dermo-S?

It is particularly suited to anyone whose skin feels fragile, reactive, tight or easily irritated and who needs cleansing that prioritizes tolerance, hydration and comfort.
