Explanation:
Yes, there are facial layers surrounding the facial muscles which can limit the spread of infection. The skin is the first line of defense against microbial invasion and serves as a physical barrier to prevent pathogens from entering deeper tissues. The epidermis and dermis are the main layers of the skin, with the hypodermis providing additional support. The normal microbiota of the skin can also play a protective role, but if an opportunistic pathogen gains access to other parts of the body through an open wound or incision, it can cause an infection.
