Every time I get out the shower, my skin is red and itchy 😢

Can anyone tell me what this is? I use all sensitive skin products, without nasty chemicals. But my skin is still like this 😭

I change products all the time to see what might help.. I have no clue.

It's all over my arms, a little bit on my body, not so much my legs.. but it calms down after I get out of the shower.

What is it?
