When patients suffer from cheilitis, they certainly should not apply lipstick. During cheilitis, cracking, bleeding, or dryness may occur. At this time, patients should apply anti-inflammatory ointments, which can promote the healing of cheilitis and also alleviate cracking and dryness. If patients apply lipstick during this time, it may aggravate the inflammation of the lips and hinder the healing process of cheilitis. Therefore, it is recommended that patients avoid applying lipstick when suffering from cheilitis. Some cheilitis might be allergic cheilitis; in this case, applying lipstick is even more inappropriate as it may also be an allergen. Hence, patients with cheilitis should pay attention to local hygiene, clean food residues, brush their teeth morning and evening, and rinse their mouths promptly after meals.
