Gallinée Youthful Serum leaves your skin feeling nourished and radiant, with a youthful glow.

Youth is something to cultivate: highly concentrated in actives, the latest Gallinée serum helps stimulate cell renewal, thanks to a cocktail of innovative bacteria. The Fern prebiotics helps to provide an immediate lifting effect and the lactic acid improves the radiance.
The complexion is brighter and skin texture is improved.
While reducing the appearance of signs of ageing, it also helps to support your good bacteria for skin that’s nourished, hydrated, and infinitely soft.

No products of animal origin. Not tested on animals.

Marie’s word, founder of Gallinée:
“Things I love about this serum: It’s oil-free, extremely light and very very efficient. I designed it as a global anti-ageing serum, so that it’s not only anti-oxidant but also smoothing and brightening. As a lazy (let’s say “time-poor”) girl, I mix it directly with the Hydrating Face Cream as a booster.”

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.

WITHOUT: Doesn’t contain colourants, perfume, parabens, mineral oils, silicones, microbeads, phenoxyethanol or methylisothiazolinone.


The Youthful Serum can be used:

o   Alone, as an initial step on a cleansed face. It is water-based texture and is very easily absorbed by the skin.

o   Mixed with the Gallinée Hydrating Face Cream for a booster effect. Apply morning or evening to a cleansed face.

RESULTS: The skin is healthy and well hydrated, the complexion is fresh and luminous, with regained elasticity.

    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!

    Sérum qui pénètre vite dans la peau avec une texture ultra douce . Très facile d’application, il est vite adopté .

    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.

    Un sérum au top ! J’adore ! Utiliser tous le soirs avant la crème hydratante Gallinée, il fait des miracles comme promis. Je n’ai pas encore de rides (25 ans) mais j’essaie de commencer à faire attention et ce porduit est une pépite ! 3 gouttes pour tout le visage et le cou et la peau se transforme nuit après nuit. Pour son prix qui est le même qu’un sérum de parfumerie plein de produits chimiques, je ne peux que remercier Gallinée et le travail derrière tous leurs produits. Merci !

  6. Snezhana

    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.

  7. Roby (verified owner)

    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!!!

  8. Marleix

    Utilisé le soir avant mon. Huile détox ou crème de nuit ou tout seul ! Parfait. 4 à 6 gouttes, pénètre rapidement, pas défait gras ni collant. Peau nickel au réveil. Bravo.

  9. 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

  10. verdier.a (verified owner)

    Une très belle découverte! Ce sérum est parfait, 3 -4 gouttes suffisent pour un effet peau apaisée et lissée immédiat.

  11. andriaj.cooke (verified owner)

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

  12. Mathilde Josserand

    J’utilise tous les produits Gallinée quotidiennement, mais le sérum est sans aucun doute mon produit chouchou de toute la gamme. Je l’utilise tous les soirs, combiné avec la crème hydratante visage, après m’être lavé le visage avec la mousse nettoyante. Le combo est incroyable. Je vois les résultats dès la première utilisation : mon teint est lumineux et ma peau en bonne santé.
    D’une manière générale, ma peau n’a jamais été aussi belle et douce que depuis que j’utilise la marque Gallinée, merci !

  13. fabiennemamich (verified owner)

    Ce sérum est un concentré d’actifs : 3 goutes mélangées à la crème visage suffisent pour une efficacité sur l’éclat de la peau. J’évite d’en appliquer autour des yeux et de la bouche car la peau est plus fine et plus réactive.

  14. 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 !

  15. Paulina Bojarska

    After 3 days of using this Serum it’s now my favourite skincare product. I already use everyday the face cream, body milk and the hand cream is always on my handbag. I really feel my skin’s microbiome is super happy and healthy.
    Thanks Gallinée.
