1. By any chance, do you use a humidifier in the summer?

I used to suffer so much from internal dryness, so I'm very sensitive to humidity. Even though I don't use it during the rainy season like now, I actually keep the humidifier on all year round because of my skin... haha. On days when I forget to use it while sleeping, in the morning...

Rather, I feel like my skin is getting oily or tight... I've been using a humidifier for two years now, and I'm not sure if it's thanks to this, but the dryness has definitely been brought under control a lot.
