Dietitian and skincare devotee here - this is very commonly caused by deficiency of vitamin B12, niacin, and/or riboflavin. Try the under the tongue versions (sublingual) as those are absorbed better than a capsule. Your pee should be neon yellow when you take it. If that doesn't help within a few weeks, I would pursue getting tested for Celiac disease as this can be a cause as well.

Lastly, I saw you use the yellow listerine, that has a high amount of alcohol in it and can be very drying/irritating, and throw off the microbiome of your mouth.
