I've used this method without leaving a scar. This method can be operated by the family, and it can definitely remove the boil that has been applied with vinegar essence.

I used pure acetic acid at that time. I wonder if you used acetic acid? White flour plays a role in slowly releasing acetic acid and fixing the burning area of acetic acid. As long as the dosage is controlled, it will not damage the surrounding good skin. But if the wart is on your face, you'd better go to the hospital. You can use this method for boils in other parts.

according to your situation, it shows that acetic acid is corroding the boils, cutting off the vascular support connection of the boils, changing a new vinegar dough every day, and the boils will wither and fall off in a few days. The tender meat will be exposed where it just fell, and it will grow up slowly in a few days.
