Be gentle with herpes ulcers, give them a chance to scab over and heal without getting infected. Eventually, the herpes sores or fissures will heal. The scab will fall off and new skin can be seen. This new skin is usually silver or red in color. Keep in mind that you might miss the scabbing stage, but you’ll probably still see this one. Once the scab has fallen off and the new skin is in place, the skin is safe to touch. At this point, the virus has retreated away from the surface and back into the nerve cluster. However, up until this point is complete, you’re still contagious.
