Undecided Question

Is it normal to have oily skin after using proactiv?

Okay well i just started using proactiv like 2 days ago because i needed a new skin care routine and i thought i would give it a try. (p.s. i didn't buy it was a gift) so anyways it seems good nothing much has happened and it makes my skin soft which i like…BUT i was just wondering if it was normal to have an oily t zone after using it. I realized that after i do the full routine i start getting an oily looking tzone and you can actually see it looks oily is that normal. i don't know it could be the moisturizer cause after i put it on it gets oily buy i don't know because i haven't tried it wothout it. so does anyone know what is the matter?
