Yes, sometimes it can be difficult to tell apart eczema and ringworm infection. Both can cause redness and itchiness on the face or on other parts of the body.
Ringworm is typically ring-shaped or oval-shaped, well-demarcated, red and itchy.
If in doubt, doctors sometimes try a trial of antifungal cream for 1-2 weeks and see if the rash responds to the antifungal cream. If it responds, then it is more likely to be ringworm/fungal infection.
From the photo, the rash looks quite well demarcated. I would suggest a trial of antifungal cream.
