Concerned about healing of flat mole after over-the-counter mole/skin tag remover. (Photo)

I used an over the counter mole/skin tag remover on a flat mole I had and a scab formed about 2-3 days later and fell off by itself maybe 2 weeks later. But for the past 4 weeks it looks red and I’m not sure if it’s still healing. Been applying neospirin to it like recommended I do.
