Is this Dyshidrosis?

I usually don’t get this. It all started in Dec 2024. I went to a country with a very cold climate (I’m from a hot and humid country). From then on, it never went away! It got better 1 month ago but it came back.

It’s so itchy and cause tears around my skin. My skin around my fingers is so thin. These blisters are only found one some fingers - my right and left thumb and middle finger) is that weird?

Any advise how to stop this? I’ve only been applying moisturizer
