What is my skin condition?

These days, my skin feels dry overall. After washing my face, it feels a little tight, and as time goes by, my cheeks and mouth feel especially dry. I think it's because of indoor heating and seasonal changes that it loses moisture easily.
Although my skin doesn't produce much sebum, it lacks moisture, so minor breakouts do occur occasionally. When I don't get enough sleep, my skin tone can appear dull and lack vitality. Fortunately, thanks to consistent moisturizing, my skin has remained relatively stable without any serious breakouts.
I feel like my skin could get better with just a little more care, and going forward, I plan to prioritize hydration and rest.
