I bought this for a friend. His first day of using the product I saw a difference. His third day, omg his face was so soft and there was a brightness to his face that wasn't there. I snitched out the vit c, I am developing wrinkles (I like to call it my eczema patch instead of wrinkles because I feel like I'm too young for wrinkles) even that has become smoother by day two Great product!! Will purchase again
