Lait S.R.

PURIFYING + REBALANCING CLEANSING MILK

Biologique Recherche Lait S.R. is a lightweight purifying cleansing milk designed specifically for combination and seborrheic Skin Instants experiencing excess sebum, shine or congestion.

Its fresh, fluid texture removes makeup, impurities and excess surface oil without leaving a heavy or greasy film behind. Rather than aggressively stripping oil from the skin, Lait S.R. cleanses while helping preserve the skin's natural balance and protective barrier.

After cleansing, skin feels fresh, comfortable and clean, with a more balanced and shine-free appearance.

Lait S.R. is particularly interesting for anyone who wants the comfort of a cleansing milk but finds traditional rich cleansers too heavy for combination or oil-prone skin.

Skin Instant:

Recommended for combination Skin Instants and skin with seborrheic tendencies. Particularly suited to skin experiencing:

• Excess sebum
• An oily or shiny T-zone
• Combination skin with both oily and more balanced areas
• Congestion
• Blackheads or whiteheads
• Clogged-looking pores
• Skin that becomes oily again quickly after cleansing
• A desire for effective cleansing without a stripped or tight feeling

Benefits:

• Removes makeup and daily impurities
• Helps remove excess surface sebum
• Purifies combination and seborrheic Skin Instants
• Helps maintain the skin's natural balance
• Cleanses without leaving a heavy or oily film
• Supports the epidermal barrier during cleansing
• Leaves skin feeling fresh and comfortable
• Promotes a healthier, more balanced and shine-free appearance

Why Oily Skin Shouldn't Feel Stripped After Cleansing

One of the biggest mistakes we see with combination and oily skin is assuming that a cleanser is working only if the skin feels extremely tight afterward.

That tight, squeaky-clean sensation is not necessarily a sign of a better cleanse.

Sebum plays an important role in the skin's protective hydrolipidic film. When cleansing is too aggressive, the skin can feel uncomfortable and its protective function may be disrupted.

The goal is therefore not to remove all oil.

The goal is to remove:

• Excess sebum
• Makeup
• Sunscreen
• Environmental debris
• Dead surface cells

while respecting the skin underneath.

This is what makes Lait S.R. different from a harsh foaming or degreasing cleanser.

It is designed for skin that produces excess sebum while still respecting the epidermal barrier.

How to Use:

• Apply Lait S.R. over the entire face, neck and décolleté.
• Emulsify using light smoothing movements, working from the inside outward and from the décolleté upward toward the face.
• Remove using wet cotton pads.
• Repeat until makeup and impurities have been completely removed.

Avoid contact with the eyes. For external use only.

Loshen & Crem’s Recommendation:

Lait S.R. is one of our favourite cleanser conversations because many clients with oilier skin think they need something foaming, aggressive or drying.

Usually, we want the opposite.

We reach for Lait S.R. when someone tells us:

• “My T-zone gets oily very quickly.”
• “My skin feels congested, but cleansers always make me feel tight.”
• “I want something that removes makeup but doesn't leave a greasy film.”
• “I have combination skin and never know whether to choose a cleanser for dry or oily skin.”
• “I loved a milk cleanser, but I need something lighter.”

That is where Lait S.R. makes sense.

It gives you the comfort and thoroughness of a cleansing milk while remaining particularly well suited to skin where oil balance, congestion and shine are part of the picture.

We especially like it as the foundation of a Biologique Recherche routine for combination or blemish-prone Skin Instants because cleansing should prepare the skin — not punish it.

Lait S.R. vs. Lait Dermo-S

These are both gentle cleansing milks, but they are designed for very different Skin Instants.

Choose Lait S.R. when your primary concerns are:

• Combination skin
• Excess sebum
• Oiliness
• Congestion
• A shiny T-zone
• Seborrheic tendencies

Choose Lait Dermo-S when your primary concerns are:

• Fragile skin
• Increased reactivity
• Redness
• Irritation
• Tightness after cleansing
• A weakened or uncomfortable skin barrier

In the simplest terms:

• Lait S.R. = purify + rebalance
• Lait Dermo-S = soothe + moisturize

If your skin is oily but also highly reactive, we would rather assess your current Skin Instant than automatically assume Lait S.R. is the best choice.

Lait S.R. vs. Lait VIP O2

Both cleanse makeup and impurities, but their priorities are different.

Choose Lait S.R. when you are primarily concerned with:

• Excess sebum
• Combination or oily skin
• Congestion
• Shine
• Maintaining balance

Choose Lait VIP O2 when the skin primarily appears:

• Dull
• Tired
• Less radiant
• In need of revitalization
• In need of broader skin-quality support

Think:

• Lait S.R. → sebum balance + purification
• Lait VIP O2 → radiance + vitality + skin quality

Lait S.R. + Complexe Iribiol

If your routine also includes active blemishes and excess sebum, Complexe Iribiol may be a complementary treatment serum.

The roles are different:

• Lait S.R. → cleansing + removal of excess surface sebum
• Complexe Iribiol → targeted serum for excess sebum + blemish-prone Skin Instants

A cleanser does not need to perform the job of every treatment that follows it.

A good routine begins by cleansing appropriately, then treating the concerns that remain.

Ingredients:

• Coco-Caprylate/Caprate & Dicaprylyl Carbonate: Lightweight emollients that help dissolve makeup and impurities while maintaining a comfortable skin feel.
• Saccharide Isomerate: Helps support moisture retention so skin remains comfortable during cleansing.
• Jojoba Esters: Help condition the skin and support a soft, balanced finish.
• Rosa Canina Fruit Extract: Rose hip-derived botanical extract included within the purifying and conditioning complex.
• Spiraea Ulmaria Extract: Meadowsweet extract incorporated into the formula for combination and seborrheic Skin Instants.
• Myrtus Communis Leaf Extract: Myrtle leaf extract included within the targeted botanical complex.
• Allium Cepa Bulb Extract: Onion bulb extract incorporated into the purifying formula.
• Commiphora Myrrha Resin Extract: Myrrh extract used within the cleanser's rebalancing botanical complex.
• Tocopherol: Vitamin E provides antioxidant and skin-conditioning support.

Frequently Asked Questions

What is Biologique Recherche Lait S.R.?

Lait S.R. is a purifying and rebalancing cleansing milk from Biologique Recherche designed specifically for combination skin and Skin Instants with seborrheic tendencies.

It removes makeup, impurities and excess sebum while helping preserve the skin's natural balance.

Is Lait S.R. for oily skin?

Yes. Lait S.R. is particularly suited to combination and oil-prone Skin Instants where excess sebum, shine or congestion are concerns.

Is Lait S.R. good for combination skin?

Yes. Biologique Recherche specifically recommends Lait S.R. for combination skin.

Its lightweight texture makes it particularly useful when some areas of the face become oily while others do not need an aggressive purifying cleanser.

Is Lait S.R. good for blemish-prone skin?

It can be particularly appropriate when blemishes occur alongside excess sebum and congestion.

Its primary role, however, is cleansing and rebalancing. Active imperfections may require additional targeted products within the routine.

Does Lait S.R. help blackheads and clogged pores?

Biologique Recherche explains that seborrheic Skin Instants can experience blackheads, whiteheads and clogged pores and emphasizes appropriate cleansing as an important step in removing excess sebum, impurities and dead surface cells.

We would consider Lait S.R. part of a pore-conscious routine rather than promise that a cleanser alone can eliminate blackheads.

Does Lait S.R. shrink pores?

No cleanser can permanently shrink or close pores.

By thoroughly removing excess sebum and impurities, however, Lait S.R. can help support a cleaner, more refined-looking complexion.

If visible pore size is your main concern, a targeted serum such as Dermopore may be more appropriate.

Will Lait S.R. dry out oily skin?

Lait S.R. is specifically designed to remove excess sebum without disrupting the skin's natural balance.

If your skin consistently feels tight or uncomfortable after cleansing, that is something we would want to reassess rather than assuming dryness is a sign the cleanser is working.

Is Lait S.R. suitable for sensitive skin?

Lait S.R. is not currently Biologique Recherche's cleanser specifically recommended for fragile or reactive Skin Instants.

If sensitivity, irritation or barrier fragility is your main concern, Lait Dermo-S may be the more targeted choice.

Can Lait S.R. remove makeup?

Yes. Biologique Recherche specifically classifies Lait S.R. as a makeup-removing, purifying and rebalancing cleanser.

For heavier makeup, you may repeat the cleansing process until all residue has been removed.

Can I use Lait S.R. as my everyday cleanser?

Yes, when it is appropriate for your current Skin Instant.

The most important consideration is whether your skin is combination or seborrheic and benefits from its purifying, rebalancing action.

Do I need to double cleanse with Lait S.R.?

Biologique Recherche recommends repeating the cleansing process until all makeup and impurities have been removed.

For some clients, this effectively functions as two passes of the same cleanser rather than requiring two different cleansing products.

Should I rinse Lait S.R. with water?

Biologique Recherche currently recommends removing Lait S.R. with wet cotton pads and repeating the application until impurities are completely removed.

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

Lait S.R. is designed for combination and seborrheic Skin Instants and focuses on purification and rebalancing.

Lait Dermo-S is designed specifically for fragile Skin Instants and focuses on soothing, moisturizing and high-tolerance cleansing.

What is the difference between Lait S.R. and Lait VIP O2?

Lait S.R. primarily focuses on excess sebum, combination skin and balance.

Lait VIP O2 is an active cleansing milk designed primarily for dull-looking skin and focuses on radiance, revitalization and overall skin quality.

What should I use after Lait S.R.?

Within a Biologique Recherche routine, Lait S.R. is typically followed by the appropriate Lotion P50 and then serums, creams and finishing products selected according to your current Skin Instant.

Who should use Biologique Recherche Lait S.R.?

It is particularly suited to combination and oil-prone Skin Instants experiencing excess sebum, shine, congestion or a T-zone that becomes oily quickly.

Where can I buy Biologique Recherche Lait S.R.?

Biologique Recherche Lait S.R. is available from Loshen & Crem online and at our Edmonton, Alberta boutique.

Our skin experts can also help determine whether Lait S.R., Lait Dermo-S, Lait VIP O2 or another Biologique Recherche cleanser is best suited to your current Skin Instant.
