For example, if someone scratches a mole until it bleeds, the resulting lesion, a crust, is now a secondary skin lesion. The most common secondary skin lesions include: 1  crust: a crust, or a scab, is created when dried blood forms over a scratched and irritated skin lesion. 2  ulcer: typically caused by a bacterial infection or physical trauma. 3  scale: patches of skin cells that build up and then fall off the skin.
1 Don't pick the scab, this will make it take longer to heal. 2  Throughout the day, put moisturizer on the scab if you can. 3  Vitamin E oil applied topically will speed scab removal and reduce severity of scar. Try not to pick or peel the scab off, this will only irritate it. 2  Try using Neosporin instead of lotion. 3  If the scab is still stuck, don't try to pick it or it will leave a scar. 4  If you pick off a scab before then skin underneath is healed, another scab will probably form. 5  Try to ignore it. 6  It will disappear.
