This Review Title is No difference and the content is: Unfortunately I did not notice a difference in the strength of my nails as the product promises. Also, it shouldn't be used as a base coat as my nail polish only lasted 2 days when using over this product. It also chips quickly as a stand alone as intended which is aggravating since it is supposed to strengthen the nail. Using nail polish remover weakens the nail as does peeling polish off. I didn't find it helpful..There are other information for this review, one is This reviewer did purchase it and the other is 1 people think this review is helpful.
