What could be causing my skin irritation after moving to a new hotel room in Thailand?

For the past three months I've been having a major skin irritation issue on my neck and lower part of my face - itchy, oily red bumps everywhere. I normally don't have this problem. It started when I moved back into the hotel where I had been living for 2 years 3 months ago but in a new room. An acne solution from Eucerine and shaving after a hot shower is helping to keep it under control, but I'm wondering what's causing it. At first I thought it was my girlfriend's makeup or hair products rubbing off onto the pillow, but it still happened when we were apart for a week and I had just had the linens changed by the hotel. At this point I'm thinking it might be one of the cleaning products used by the cleaning company. Maybe they changed it recently and I'm allergic to it? I asked the staff if they could find out what cleaning products they use, but they haven't reported back yet. I'm assuming bleach because everything is bright white. Perhaps too much of it? What do you guys think it could be? Any ideas for how to tackle it? Has anyone else experienced this problem and figured out what the culprit was? Other possibilities I guess could be bacteria brought inside from my dog, a fungus or something in my room, pollutants in the air, etc. Thanks!
