yes you should be concerned. scabs and sores are not supposed to be on your face. one concern would be an infection such as impetigo but you would need to see a medical provider in order to be properly diagnosed and treated. this diagnosis cannot be made blindly based solely on a vague description so please get these sores checked out professionally.
i have three sores/scabs on my face; what are they and should i be concerned? . the sores orginally started out from one small minor sore and gradually it spread over time. now i have three right next to each other and they are not healing.
