Once the scab starts to come off you will enter the last stage of the cold sore cycle which is the healing stage. The skin underneath the scab will be dry and flaky with a pink or red tinge to it. It is important that you moisturize the lips to ensure that the cold sore does not leave any scarring. The healing stage could last up to 5 days.
