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!!!
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.
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
Une très belle découverte! Ce sérum est parfait, 3 -4 gouttes suffisent pour un effet peau apaisée et lissée immédiat.
Have not used a serum before but am loving this product. I like to use it mixed with the face cream at night.
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 !
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.
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 !
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.
