    A atténué mes tâches d’hyperpigmentation

    J’applique ce produit depuis un moment et j’observe une réduction des tâches d’hyperpigmentation dûes à des cicatrices de bouton.C’est vrai qu’il a une légère odeur souffrée, mais c’est pas invivable non plus comme l’ont dit certains en commentaire (parce qu’en les lisant limite j’avais envie de retourner le produit sans le tester).Je suis très satisfaite 😊 n’oubliez pas d’appliquer un SPF50 par dessus si vous le mettez le matin! ☀️

    You can get over the smell

    Probably one of the best Vitamin C serum out there. Sure, there's a strong smell but it goes away after a few minutes. I've read one review where it supposedly made someone sick and that's just not scientifically possible. Unlike other VC serums I've used, this one seems to lock in moisture. While it does have a slightly oily texture to it, it's nothing to worry about especially if you apply (which you should) moisturizer after. It definitely leaves a nice glow and it's part of my morning routine prior to apply moisturizer and SPF.
