DO NOT
Can I use hot glue to close a cut?
No, using hot glue on a cut is a terrible idea—it's unsafe, painful, and risks infection.
Hot glue isn't meant for your skin and can cause burning, irritation, and infection if applied to a wound. Medical glues are specially designed for skin and sterile conditions, unlike your crafting supplies. If you have a cut needing closure, clean it thoroughly and seek proper medical treatment, not your arts and crafts kit.
Avoid using any non-medical adhesives on wounds; seek professional medical care for deep or bleeding cuts.
