Cracking at the corners of the mouth is most commonly a vitamin B2 (riboflavin) issue. Notice I said issue, not deficiency. Taking a B-Complex or B2 by itself may resolve the cracking, but it is not usually the answer. Most people get enough B2 daily, even from poor sources such as enriched breads in an unhealthy diet. Unfriendly bacteria, living in the digestive tract love B2, and they use up your available B2 for fuel. Therefore, while taking a B2 supplement may help you somewhat, at the same time you’re also helping the bacteria to thrive. Obviously the answer here is to get rid of the bacteria. Carbohydrates, especially simple and refined sugars also help the bacteria flourish, this includes both fruit and fruit juice, as they will feed the bacteria.

Do you know how to get rid of xyanthelasma under the eye area?
Dr. Stephen Gangemi says
Typically that’s a fat metabolism issue – but tough to get rid of once you have them (easier to prevent with diet).
