yes say you put moisturizer on you're skin it goes in and blood comes out
Pathogens from everywhere
The skin

your boogers
In the human body, the primary line of defence is the skin. The skin stops most of the microbes from entering the interiors of the body. If however, the pathogen is able to gain access into the body, the lymphatic system comes into play. The pathogen is eliminated before it begins to cause any more trouble.
Cilia protect your body from pathogens up to a certain extent. The cilia in your lungs prevent dust particles and other such particles you breathe from entering your lungs by trapping them and sweeping them away. The cilia located on the cell membrane prevents certain substances from entering the selectively permeable cell membrane through that same manner. However, if you get a cut or something, cilia are not really going to protect pathogens from entering your body from that cut.
The skin
High skin resistance can produce severe skin burns but prevent the current from entering the body
The pores on your skin help to prevent harmful pathogens from entering. Pathogens cause disease, infection and Cancer. By keeping these pathogens out, this is how pores protect you.
Skin prevents microbes from entering your body...

THere are many barriers to prevent foreign organisms and viruses from entering your body. These include the skin, the mucous membranes of the respiratory system, the stomach acid, the enzymes in your tears, and the immune system.
Your skin and your mucus membranes are your body's first line of defense against any pathogen whether that be dust, or a virus!
The skin den the second layer is the phagocyte. These are the barriers of the skin.
Yes, skin serves as a barrier to protect the body from external threats such as infections, UV radiation, and physical damage. The outermost layer of the skin, the epidermis, provides a physical barrier while also producing oils and acids that help to prevent pathogens from entering the body.
It doesn't.
There are three major non-adaptive or innate defenses in the skin to prevent the entry of pathogenic organisms.Keratin acts as a physical barrier to prevent moisture from escaping and pathogens from entering.Sebaceous glands in the skin produce sebum which is an oily substance that can inhibit the growth of some bacteria.Epithelial cells produce antimicrobial peptides called defensins.
The skin is only a defense to stop bacteria from entering the body.
