Due to the varying nature of dermatitis and how it differs from person to person, it can sometimes be tricky to identify the reason behind it. However, if you can find out what’s causing your skin to flare up, then there’s a good chance that your skin will respond to improved conditions. Try changing certain things in your day-to-day lifestyle and see if things improve. For instance, you could switch your washing powder, avoid wearing certain fabrics, use unperfumed products, and don’t wear nickel earrings.
