My son has this reaction from Ranch dressing. He eats it all the time but when it gets on his face he gets red and sometimes swelling. He has been eating ranch since he was about 10 months old, and he is now 3 and it still happens. I just try to wipe immediately. I also keep a napkin for him next to him and now he is learning to wipe himself right away. Not always with the napkin, he often goes for his sleeve, LOL. I have noticed he also sometimes gets red from the sauce on pizza. I think it is just a skin sensitivity since he eats everything no problem, and he has been tested for allergies since his sister has some pretty severe food allergies, but he has none at all. Just try to wipe him right away.
