Why does my skin itch?

I have persistent itching in a specific area of ​​my skin.
I'm wondering if this could be a skin condition
Or it could simply be due to dry skin caused by lack of moisture.
I wonder if my skin is itchy.
Actually, when my skin was itchy, I scratched it hard ^^;;;
I don't think that's right... but I'll go to a dermatologist first
Should I get the material?
I should go to the hospital. I keep thinking about it and putting it off.
It's time to worry about itchy skin againㅜ
