My lips are cracked and inflamed at the corners... can I apply lip balm to them?

When we were young

You know I told you the corners of my lips split to make them bigger.

I have been experiencing recurring symptoms of cracked corners of my lips and inflammation for a long time.

This is actually quite stressful.

It didn't show up in the photo, but the corners of my lips are cracked.

Is it okay to apply lip balm bought at the pharmacy here?

Or would it be better to go to a dermatologist and get a prescription for ointment?

I'm really conflicted.

I wonder if this is happening because of a lack of nutrients.

I eat well, so I don't know why this symptom keeps repeating for so long.
