If you have cracked skin at the corners of your mouth, it may be a condition called angular cheilitis. This condition is caused by inflammation at the corners of the mouth, leading to redness, swelling, and painful cracks. Some of the causes of angular cheilitis include:
-
Dry skin: Very dry skin at the corners of the mouth can lead to angular cheilitis. Saliva can collect in this area and cause dryness, which can lead to cracking.
-
Dehydration: Dehydration is one of the major causes of dry mouth, which can increase the likelihood of developing angular cheilitis.
-
Health conditions: People with certain health conditions, such as uncontrolled diabetes, are more likely to develop angular cheilitis due to increased urination and dehydration.
-
Allergies and irritants: Contact with skin allergens and irritants can increase the risk of developing angular cheilitis.
To treat angular cheilitis, you can try applying a moisturizer that contains petroleum jelly around your lips to provide a seal over the skin and prevent saliva from disrupting the outer layer. You can also use a non-irritating lip balm or lip moisturizer several times a day and before bed to keep your lips moisturized and protected. If your lips are very dry and cracked, try a thick ointment, such as white petroleum jelly, which seals in water longer than waxes or oils. Some ingredients that can help heal chapped lips include ceramides, dimethicone, hemp seed oil, mineral oil, petrolatum, shea butter, and sun-protective ingredients such as titanium oxide or zinc oxide. However, it is important to avoid lip products that contain camphor, eucalyptus, and other ingredients that can irritate dry, cracked lips. If the cracks still come back frequently, it’s time to see a dermatologist.
