How to get rid of redness around this cut?

Redness around a cut: This is due to inflammation from the cut and perhaps there is an infection causing inflammation or it may be just the healing process.

Diagnosis first: Hi, it’s hard to say without a picture but there is a great app that may be able to help you get a diagnosis without being seen in person by a dermatologist. The app is called VisualDX and is one of the best, if not the best out there. Many clinicians, including myself, use it. Just snap a photo and it gives you a list of possible diagnoses. Good luck!
