"Visite dans la boutique pour rechercher un soin : deux vendeuses inoccupées, l’une sur l’ordinateur, l’autre sur son téléphone. Résultat : le soin n’est pas celui dont j’avais besoin, et je n’ai eu ni bonjour, ni merci. Bravo pour ce manque de politesse et de professionnalisme !"

"Ottimo prodotto. Grazie all'aiuto della consulenza personalizzata ho potuto usarlo al meglio. Comunque ci vogliono circa 3 settimane prima di vedere i risultati"

WOW! This stuff works. I've

"WOW! This stuff works. I've tried so many things to make my flimsy and peeling nails stronger, to no avail. I didn't really have faith in this product but it truly makes a difference in less than a week, they became harder! It's also so low maintance and I love that it's a product that absorps into the nailbed instead of a layer of nailpolish."
