I'm worried because my skin often gets itchy. What should I do?

I am worried because my skin often gets itchy.

I'm not sure if it's because my skin is dry or if it's an allergic reaction, since I didn't use any new products.

It gets worse especially at night when you sleep, and scratching can cause the skin to become red and irritated.

I applied a lot of moisturizer and even tried a pack, but it didn't seem to make much of a difference.

Has anyone else had a similar experience? I'm curious about how you managed itchy skin, and what dermatological procedures or treatments might be helpful.

Itchy skin causes inconvenience in my daily life. If you have any effective management methods or tips, please share them with me.
