Angular Cheilitis how should I treat it? [Product Question]

​

I have had sores on the corners of my mouth for over a week now. I have been using vicks vaporub and chapstick as well as taking B12 vitamins but it won't go away.

Today I bought an anti-fungal cream and a cold sore cream.

I'm just not sure which one I should be using.

The anti-fungal is also made for athletes foot, so I don't know how safe that is but it's all I could find
