From reading the description of the product, I was a bit disappointed that it did not help remove my "spot" (blemish). I used it several days without any results. Effectiveness it was not effective for me. I am planning to return the item. :( Ease of Application It went on smoothly; however, did not get the results I expected. Convenience It was in a super small container and easy to use. Convenient, but not effective. Side Effects I had no side effects; however, product did not work for me.
