Sophie B. published the 28/11/2022 following an order made on 24/10/2022


J'ai une peau réactive et j'ai pensé que les produits quasi naturels seraient bons.... Pas du tout ! J'ai une des boutons dès le lendemain. Dépenser autant d'argent pour des produits que je ne mettrai jamais c'est vraiment rageant ! Je ne commanderai plus jamais
