How To Treat Cheilitis & Cracked Corners Of Mouth

Cheilitis is a common lip condition that causes dryness, redness, inflammation, peeling, and painful cracking. In some cases, it progresses into cracked corners of the mouth, also known as angular cheilitis. This guide explains the causes, solutions, and prevention in a clear and balanced way.


What Is Cheilitis

Cheilitis refers to inflammation of the lips. It can appear as mild dryness or develop into painful cracks, swelling, or sores. Some people experience it occasionally due to weather changes, while others struggle with recurring flare ups caused by underlying factors.


Common Types of Cheilitis

Type What It Looks Like Typical Triggers
Angular cheilitis Cracks and soreness at mouth corners Fungal or bacterial infection, excess moisture
Contact cheilitis Red, itchy, peeling lips Irritation from lip products or toothpaste
Actinic cheilitis Thickened, rough lower lip Long term sun exposure
Atopic cheilitis Chronic dryness and inflammation Eczema or sensitive skin

What Causes Cheilitis

Cheilitis often develops when the lip barrier is weakened. Environmental stress, habits, or health related factors can all contribute.

Dry or cold weather can strip moisture from the lips, while frequent lip licking further damages the skin barrier. Dehydration slows healing, and vitamin deficiencies, especially B vitamins and iron, can make lips more prone to cracking.

Angular cheilitis is commonly associated with fungal or bacterial overgrowth at the corners of the mouth. Allergic reactions to cosmetics or oral care products may also trigger inflammation, as can prolonged sun exposure.


How To Treat Cheilitis

If you are wondering how do you treat cheilitis, the goal is to:

  • Restore moisture
  • Reduce irritation
  • Address any underlying causes

Keeping lips well moisturized is essential. Apply a gentle, nourishing lip balm regularly throughout the day, especially after eating or drinking. Avoid products that cause tingling, burning, or dryness, and stop using lipsticks or glosses if irritation appears.

Staying hydrated supports overall skin repair, while protecting lips from sun exposure helps prevent chronic damage. If cracked corners of the mouth persist, treatment may need to address a possible fungal or bacterial infection with professional guidance.


How To Heal Cracked Corners Of Mouth

Cracked corners of the mouth can be particularly painful and slow to heal without proper care.

Healing Focus Why It Helps
Keeping the area clean and dry Reduces infection risk
Using a barrier lip product Prevents reopening of cracks
Avoiding excessive mouth stretching Allows skin to repair
Improving nutrition Supports faster healing
Managing saliva buildup Prevents recurring irritation

With consistent care, angular cheilitis usually improves within one to two weeks.


Choosing the right lip products plays a major role in healing cheilitis and preventing flare ups. Gentle formulas that support moisture retention and barrier repair are especially important.

When To Seek Professional Advice
