I received this product free from Influenster and AGENCY in exchange for my honest review. It was really cool being able to consult a dermatologist from the comfort of my home. I narrowed down my main concern to my dark spots and had my formula made for that problem area. I found it did drastically reduce the visibility of the dark areas. I have plenty of product to last me longer than the 3 months I tested. The only negative I found was the off-putting smell of the formula.
