(Question) My skin is very itchy. Is it because it is dry?

Even in the summer, my skin was sensitive, so it was itchy.

It's winter, so my skin definitely gets itchy and scratching is a daily routine.

If you scratch, it may bleed and the itchiness gets worse especially before going to bed.

Even if you're tired and want to go to sleep right away, you might miss out on sleeping time because you're scratching.

I tried all the body lotions that were said to be good and thought I moisturized my skin a lot, but I have no idea ㅠ

They say it's because it's dry, but what's the cause?

I don't have any food allergies ㅠ Or is there a separate medicine that can stop the itchiness???

If there is a way to get better with home care, please let me know!
