Hi Doctor, I Have Been Using Tenovate N For A

Hi Doctor, I have been using Tenovate N for a few months hoping to lighten my pigmentation. During this time not much changes. I have stopped using it for about two weeks and noticed that pimples coming out. Is Tenovate N the same as Tenovate GN. I am now stopping it after reading that it is considered a topical corticosteroid type. Will there be more side effect after this.Thank you.
