I'm curious about the causes and management of skin itching that gets worse with age.

Lately, I have been very concerned because my skin itching seems to be getting worse as I get older. I don't have any specific allergies, nor have I used any new products, so I'm not sure why. I wonder if it is due to dryness or if my skin barrier has weakened. I would also like to know if this is a common occurrence and if it can be improved through lifestyle habits or care methods. For instance, would applying moisturizer more frequently or avoiding harsh detergents help? I am also curious if changing my diet or lifestyle habits could alleviate the symptoms. It would be very helpful if those who have actually experienced this could share how they reduced skin itching and whether those methods were effective.
