Patients who develop angular cheilitis may generally be experiencing a vitamin deficiency, or it may occur in relatively dry seasons, leading to breaks at the corners of the mouth. It could also be a result of internal heat in the body, causing angular cheilitis, also known as cracked corners of the mouth. It is generally not advisable for patients to apply aromatic oils as they do not have antibacterial properties and may even facilitate bacterial invasion. It is suggested that patients use some anti-inflammatory ointments, such as erythromycin ointment or gentamicin eye ointment, which can help reduce inflammation and heal the skin's soft tissue damage. Therefore, it is recommended that patients seek medical advice and apply medications prescribed by a doctor. Additionally, when applying ointments, do not use hands directly; instead, use medical cotton swabs and maintain personal hygiene. (Medication use should be under the guidance of a physician.)
