How to Heal Cracked Lip Corners Fast

Cracked lip corners can be a little tricky to treat because of the folded skin tissue and presence of moisture. While there are many remedies touted to help with cracked lip corners, not all of them provide a cure. Some remedies bring temporary relief while others exacerbate the problem. So, what can you do to heal cracked lip corners? Here is where to start;

DO NOT Lick your Lips

Due to the inflammation and irritation, you are likely to keep licking the area. This draws out more moisture making thus more cracking. Once the cracks form at the corners of the mouth accumulation of saliva or contamination can lead to secondary infection.

Use a Mild Toothpaste

The presence of cracked lip corners may simply mean that you are reacting to your toothpaste. Some kinds of toothpaste have strong acidic ingredients that aggravate pain and irritation on cracks that have already formed.

You may have to go for an allergy testing to determine whether your toothpaste is really the culprit. If so, try products that are made for sensitive teeth and gums such as;

  • Sensodyne
  • CrestPro Health
  • Colgate Sensitive Pro Relief
  • Oral B Sensitive Advantage

For cracked lip corners associated with nutritional deficiencies, supplement or eat diets rich in the B vitamins, Vitamin E, and zinc. Food rich in Iron is also very essential.

It is important to note that nutritional disorders are not only caused by malnutrition due to poor intake. It may also be due to malabsorption due to gastrointestinal disorders such as celiac disease, gastrointestinal surgeries, alcoholism and strict vegan diets.

Stay away from foods that trigger local allergies in the mouth. Avoid acidic foods such as pineapples, alcoholic drinks and those that may cause injuries such as sugarcane.


Stay hydrated by drinking plenty of water.


It is common to make the assumption that slathering a layer of jelly on your lips is enough to treat cracked corners of the lips. It is NOT! While it may offer relief for symptoms such as crustiness and pain, it may also be the reason why you develop an infection.

Since the skin is a little folded at the corners, accumulation of moisture from balms and saliva slows down healing. Moisturizing will only help if the cause of your cracked lip corners stems from dry lips. Use medicated balms and those that have non-allergic ingredients.
