Fast Answer
Yes, dermatitis commonly causes redness and swelling. Inflammation damages the skin barrier and increases blood flow to irritated areas, which can make the skin appear red, puffy, warm, sore, and inflamed during flare-ups.
Why does dermatitis cause redness and swelling?
Dermatitis triggers inflammation inside the skin. As the immune system reacts, blood vessels widen and more blood flows to irritated areas.
This can cause the skin to become:
- red
- swollen
- warm
- sore
- irritated
- tender
Some people experience mild redness, while others develop intense inflammation during flare-ups.
