Angular cheilitis is a relatively common phenomenon during the autumn and winter seasons, generally due to the dry weather, which may cause the lips to crack. If the lips have not yet cracked, applying lip balm regularly can help moisturize and repair the lips. However, if angular cheilitis occurs and there is already some skin damage and peeling, it is recommended that patients apply an anti-inflammatory ointment, which can aid in anti-inflammatory repair. Lip balm can generally be used for daily application to moisturize, but it is still recommended that patients seek appropriate treatment and possibly take some vitamins or trace elements orally.
