help!!

Summer just started for me and I completely stopped putting on makeup for over the summer, but I’ve started to break out more than I did before when I was wearing make up. I wash my face twice a day and have a good moisturizer, I’ve changed nothing in my routine except for not wearing anymore makeup. I also drink lots of water throughout the day. Has this happened to anyone else or does anyone have any ideas about what the problem could be and what might help?? I’m at a complete loss.
