I have some questions about itchy skin, causes, and treatments.

I didn't know that Maypure could treat this area.

This phenomenon occurs more frequently during the changing seasons. I am curious about the causes and treatments for itchy skin.
Recently, I have been experiencing itchiness more frequently, and I am suffering from itchy skin several times a day.

Itching is particularly severe on the entire back and lower chest area.
I think it might be due to dryness, so I use moisturizer regularly, but it doesn't fundamentally solve the itchy skin.
What causes itchy skin, especially in certain areas (like my back and under my chest)?
