Key Ingredients

PROBIOTICS: A powerful cocktail of bacteria from the Lactobacillus and Lactococcus families, these probiotics are extremely gentle on the skin and help to support the microbiome and stimulate cells renewal.

PREBIOTICS: A mix of ultra-gentle fibres and sugars that feed your skin’s good bacteria and help support the skin’s barrier, with an antibacterial action against bad bacteria.

FERN EXTRACT: Gallinée is using a specific polysaccharide extracted from fern for its prebiotic effect and its unique properties to help reveal skin that is firmer and appears lifted.

LACTIC ACID: The gentlest of AHAs, lactic acid helps the skin to stay at its optimal pH level and has hydrating and softening properties. Gallinée uses a slow-release form to suit even sensitive skin.

PHYSIOLOGICAL PH: All Gallinée products are made to match the optimal pH of the skin and the microbiome.

    I have a mild form of dermographism and I noticed the serum really helped to reduce the redness. I use it in the evening after the Cleansing Bar (occasionally in the morning as well) . This combination leaves my skin nourished and so soft! The effect is still visible the next morning! Definitely recommend!

    I have received this serum as a birthday gift (yaaay!) and I am in love with it! Having an oily but dehydrated skin it really helps to balance it and my face does feel plump after a couple of uses. I only need to apply a little amount before my cream so it lasts ages! I will definitely buy it again once it runs out!

    It’s ok to use during pregnancy?

      Hello Camila!
      Thank you for contacting us.
      The products haven’t been tested specifically on pregnant women, but they have been developed on sensitive skins and have nothing that can provoke reactions (like essential oils etc…). On the other hand, because there is lactic acid in the products, we recommend putting sunscreen before sun exposure.
      Have a lovely day.

    Amazing! Would recommend it to everyone with seborrhea dermatitis. I am applying it the morning mixed with La Culture face cream and the redness around my nose has disappeared. Plus, is a wonderful base for foundation as it gives the face great glow and very natural look.

    This serum is working greatly for the seborrheic dermatitis on my face. Since I have been applying it morning and evening, the red and scaly skin patches forming around my nose and eyebrows have disappeared. Fabulous!!!

  6. Lili

    The best serum I’ve tried so far! The product is very concentrated so no need to put that much on.
    I use it before daily cream and before going to bed. My skin is so soft after an hour, baby style!
    Definitely recommending

    Have not used a serum before but am loving this product. I like to use it mixed with the face cream at night.

  8. Françoise Bohan

    J’ai essayé le nouveau produit de la gamme dont je suis fan,le sérum. Sa texture est immédiatement absorbée et peu de gouttes suffisent. J’ai une peau mature un peu abimée par le soleil… et bien l’utilisation (matin et soir) du sérum a un effet livrant immédiat et laisse la peau douce. Le soir je n’ajoute aucune crème! Juste la mousse démaquillante( ma préférée) et 3 gouttes de sérum bien chauffées au creux des mains avant application. Merci gallinée !
