In the first photo I see a woman having a headache / who has a headache. She should go to a general practitioner. In the second photo I see a man's eye. It has red color and looks very tired. Maybe the man just needs to relax but if he has some problems with his eyes, he should go to a ophthalmologist. If I don't mistake, the man in the third photo has some problems with his skin. I think, this way, how he solves his problem, is not very good. He should go to a dermatologist.
