My cheeks have been itching constantly lately. Could it be dehydration?

I do have flat warts, but they aren't on my cheeks.

It's not like anywhere else, but my cheekbones and cheeks are itchy.

I haven't changed my skincare routine and am using the exact same products, so could it be due to a lack of moisture? (I do have dehydrated oily skin, but it is actually very oily.) Or is it because the weather is getting warmer and more humid?

Could it be because of the mask?

I know I shouldn't scratch it, but it's so itchy that I keep poking it with the tips of my fingernails, but I don't think that's good for my skin either.

Is there any way to temporarily relieve itching while I am outdoors?
