How should I manage the black protrusions like skin tags and warts that appeared sometime ago?

Skin tags also appear at some point and are often found around the neck.

And I thought it was a skin tag, but it grew a bit larger and looks like a small lentil bean.

The surface is rough and dark, and it bothers me, so I peel it off bit by bit with my nails.

In that case, the size is always that size.

These kinds of things become quite stressful over time.

I don't really want to go to the hospital.

How should I manage it?
