Talk to Dermatologist on Itching

I've been feeling itchy on my hands and legs for the past few weeks, so I started using moisturizer and non antiseptic soap. Although I’ve noticed a slight improvement, but the itching still persists. Recently, with the change in weather, the itching has become more intense, especially after coming back from outside – it affects my whole body. The issue is that I can't see any visible rash or bumps, just some redness in the areas where I'm itching, which makes it hard to identify the cause or show it to anyone.
