Cheilitis and herpes labialis are generally two different conditions. Cheilitis has a broader meaning and may include allergic cheilitis, or dryness during autumn and winter, cracked lips, and angular cheilitis. For example, common oral herpes is generally referred to as cheilitis. Additionally, cheilitis broadly includes any inflammation of the lips. However, herpes labialis is usually due to a decline in the patient's immune system, leading to a herpes virus infection, so herpes labialis is a simple viral disease. Therefore, there is a distinction between the two. Cheilitis might involve bacterial infections, in which case anti-inflammatory ointments can be applied. If it is herpes labialis, antiviral treatment is generally used.
