Product details
A closer look.
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 look. Dehydrated skin lacks water; undernourished skin lacks lipids. Colostrum VG is especially valuable when the skin lacks both.
Why you’ll love it.
We reach for Colostrum VG when a client tells us their skin drinks everything they put on it, or feels dry no matter how much moisturizer they use. Sometimes the answer isn't simply more hydration: if the skin lacks lipids, it may have difficulty holding onto the water you give it. We particularly love it during colder months, in dry climates or whenever the skin feels depleted and less resilient than usual. Think of it as a deeply comforting serum for skin that needs both water and nourishment.

Your questions, answered.
Is Colostrum VG for dry or dehydrated skin?
Both. Biologique Recherche recommends it specifically for skin that is dehydrated and undernourished, which makes it particularly useful when the skin lacks both water and lipids.
Is Colostrum VG a moisturizer?
No. It is a serum, generally applied before your Biologique Recherche cream or moisturizer.
What is the difference between Colostrum VG and Amniotique VG?
Amniotique VG primarily focuses on water-focused hydration. Colostrum VG provides hydration while also replenishing lipids, for skin that feels dry, undernourished or unable to retain moisture comfortably.
What is the difference between Colostrum VG and Sérum T.E.W.L.?
Colostrum VG is a serum focused on hydration and lipid replenishment. Sérum T.E.W.L. is a richer, oil-rich finishing serum designed to act as a protective lipid shield and help reduce transepidermal water loss. For very dry Skin Instants, the two may complement each other in a professionally prescribed routine.
Can I use Colostrum VG every day?
Yes. Apply a few drops morning and/or evening according to the needs of your Skin Instant.
When should I apply it?
After cleansing and your appropriate Lotion P50, and before your moisturizer.
