AviClear after one year. Would I benefit from more sessions to maintain the results?

I am one year post Aviclear and two months postpartum. I finished it in October and got pregnant in January. I noticed my skin was much less oily and less breakouts only whiteheads here and there whereas before I would get hormonal acne so I am now two months postpartum and noticed my skin got a bit more oily, and some whiteheads emerging more often. I am wondering if pregnancy and postpartum affects Aviclear results and if so, would I benefit from more sessions to maintain the results?
