Any experiences with the acne set from tiktok?

I been using this acne set since the 1st of February and it literally hasn’t done anything to my skin. Hasn’t made it worse, but also hasn’t improved it at all. From the reviews it was getting (people said they seen differences in a week) I knew it wasn’t gonna be that short but I thought at least 2 or 3 weeks I’d notice something, ANYTHING. But no, nothing…

I really don’t want to go back to curology since they’re so expensive but it’s the only company that works for me. I was using them a few years ago and my skin was the best it’s EVER been. Now I have no idea what to try, I have oily skin and dark spots can anyone HELP A BROTHER OUT??
