Très bonne surprise

Je l'utilise depuis deux semaines et j'avoue être agréablement surprise, car je suis de nature plutôt méfiante...l'effet éclaircissant est réel et ma peau est plus éclatante. Je le pose le matin en massant légèrement . Le flacon est pratique, celà permet de poser la quantité exacte.
