Serum Colostrum VG

FUNDAMENTAL HYDRATION SERUM +++

Biologique Recherche Colostrum VG is an intensive lipid-replenishing serum created for skin that is not only dehydrated, but also lacking nourishment and essential lipids.

Its rich, cushioning formula helps replenish the skin’s protective lipid film while supporting optimal water levels within the epidermis. This dual action helps reduce surface dryness, restore comfort and reinforce the skin barrier so moisture is better retained.

The result is skin that feels softer, more supple and deeply comforted, with a visibly plumper and healthier-looking appearance.

Colostrum VG is especially valuable when simply adding more hydration no longer seems to be enough.

Skin Instant:

Recommended for dehydrated and undernourished Skin Instants.

Particularly suited to skin experiencing:

• Persistent dryness or tightness
• A lack of lipids or nourishment
• Flaking or rough texture
• Reduced suppleness
• A weakened-feeling skin barrier
• Skin that struggles to retain moisture
• Seasonal dryness or increased discomfort in cold, dry environments

Benefits:

• Provides intensive, long-lasting hydration
• Replenishes lipids within the epidermis
• Helps strengthen and support the skin barrier
• Reduces the appearance of surface dryness
• Helps limit moisture loss by supporting the lipid film
• Restores softness, suppleness and comfort
• Helps visibly plump dehydrated-looking skin
• Supports greater resilience in dry and undernourished skin

Dry Skin vs. Dehydrated Skin: Why It Matters

Dryness and dehydration are not exactly the same thing.

Dehydrated skin lacks water.

It can feel tight, look dull or show fine dehydration lines — and it can occur even in combination or oil-prone skin.

Undernourished or lipid-deficient skin lacks oil and lipids.

It may feel persistently dry, rough, uncomfortable or flaky because the protective lipid film is not functioning optimally.

And sometimes, skin is experiencing both at the same time.

This is where Colostrum VG becomes particularly interesting. Rather than focusing exclusively on adding water, its formula combines hydration with lipid replenishment to help restore comfort and reinforce the skin’s protective barrier.

How to Use:

Apply a few drops morning and/or evening over the face, neck and décolleté.

Gently massage using light upward movements until completely absorbed.

Within a Biologique Recherche routine, apply after cleansing and your appropriate Lotion P50 and before your moisturizer.

For external use only.

Loshen & Crem’s Recommendation:

Colostrum VG is one of the Biologique Recherche serums we reach for when a client tells us:

• “My skin drinks everything I put on it.”
• “My skin is hydrated for an hour and then feels dry again.”
• “My face constantly feels tight.”
• “My skin feels dry no matter how much moisturizer I use.”

That last one is important.

Sometimes the answer isn't simply more hydration. If the skin is lacking lipids, it may have difficulty holding onto the water you're giving it.

That is where Colostrum VG earns its place in a routine.

Think of it as a deeply comforting serum for skin that needs both water and nourishment.

We particularly love it during colder months, in dry climates, during periods of increased skin dryness, or whenever the skin feels depleted and less resilient than usual.

Colostrum VG vs. Amniotique VG

Both are Biologique Recherche hydration serums, but we don't reach for them for exactly the same reason.

• Choose Amniotique VG when the primary concern is dehydration — a lack of water : The skin may feel tight, dull or thirsty but does not necessarily feel persistently dry or lipid-deficient.
• Choose Colostrum VG when the skin needs hydration + lipid replenishment: Think dryness, reduced suppleness, persistent tightness or skin that does not seem to hold hydration very well.

In the simplest terms:

• Amniotique VG = water-focused hydration
• Colostrum VG = hydration + lipid replenishment

Your Skin Instant can change, so the serum that makes sense for you in summer may not necessarily be the same one your skin needs during winter.

Colostrum VG vs. Sérum T.E.W.L.

This is another common question.

Both products support lipid-deficient skin, but they occupy different roles within the Biologique Recherche routine.

• Colostrum VG is a moisturizing and lipid-replenishing treatment serum designed to restore comfort, hydration and suppleness.
• Sérum T.E.W.L. is a richer finishing serum designed to act more like a protective lipid shield, helping reduce transepidermal water loss in Skin Instants severely lacking lipids and nourishment.

Think:

• Colostrum VG → replenish and hydrate
• Sérum T.E.W.L. → protect and help limit water loss

For very dry or lipid-deficient Skin Instants, the two may sometimes complement one another within a professionally prescribed routine.

Ingredients:

• Caprylic/Capric Triglyceride: A lightweight emollient that helps replenish lipids, soften the skin and support its protective barrier.
• Glycerin: A humectant that attracts water to the skin and helps maintain hydration.
• Saccharide Isomerate: A moisture-binding ingredient that helps support lasting hydration and skin comfort.
• Luffa Cylindrica Seed Oil: A plant-derived oil that helps nourish lipid-deficient skin and support suppleness.
• Alisma Orientale Extract: A botanical extract included within the serum's targeted moisturizing and lipid-replenishing formula.
• Tocopherol — Vitamin E: Provides antioxidant support while helping condition and protect the skin.
