Some home remedies for cracked corners of the mouth include honey, lip balms and moisturizers, aloe vera gel, water, cocoa butter and cucumber. Having cracked corners of the mouth is a common condition also known as Angular Cheilitis.
Cracked corners of the mouth can be unattractive and painful, causing discomfort particularly during the winter. Just like chapped lips, cracked corners of the mouth are often the result of dehydration and extreme dryness, but other causes may include bacterial or viral infections, a poor diet, autoimmune disorders, allergic reactions to cosmetic products or food, overexposure to sun or heat, and iron or zinc deficiencies. According to WebMD, increasing fluid intake to prevent dehydration can be of help. Protecting the lips with a lip balm and avoiding sun and wind exposure can also be beneficial. Petroleum jelly is one of the best choices because some balms can contribute to further dehydration. Rubbing a slice of fresh cucumber on the affected areas can decrease the discomfort. Applying honey on cracked corners of the mouth often works because of the moisturizing and antibacterial properties of honey. To keep the lips soft no matter the weather conditions, apply some vitamin E to the corners of the mouth.
