There is a minimal risk of infection due to eye threading. Everyone needs to be aware that there is a risk with threading, and you need to make sure that there is a clean thread, and the person is washing their hands. It does carry health risks, including the potential spread of the herpes
virus and staph infections through dirty threads and broken skin. Please consult your doctor should there be further signs of inflammation and tenderness.
Hope this helps
