“Mr Shen Du, the folliculitis is endless, what did I do wrong?”
“Mr Shen Du, where did the boil come from? Can’t you squeeze it with your hands?”
What exactly is folliculitis? Why does good skin have pimples? What is a long boil?
Where there are doubts, there is Shendujun. Today, Shendujun will tell you the core secret of folliculitis. Dear fans, are you ready? “Pathogenesis of Folliculitis”, let’s go!
The skin is the largest organ of the human body, with functions such as perspiration, protection of the body, and regulation of body temperature. From outside to inside, it is divided into epidermal layers , dermis, and subcutaneous.
Human skin, with the exception of palms and soles, is basically hairy.
These hairs play different roles depending on their location on the body:
Hair protects the head and keeps you warm;
lashes prevent dust, sweat, etc. from entering the eyes;
nose hair filters out harmful substances in the air;
Legs can dissipate heat and promote perspiration.
If you want to know about hair follicles, you should start with this hair.
The part above the skin surface is called the hair shaft; the part below the skin surface is called the hair root< /strong>.
The ring of epithelium and connective tissue surrounding the hair root is the hair follicle.
The sebaceous glands near the hair follicle contain sebum, which moisturizes and protects the skin.
Hair follicles are like soil that nourishes hair, and there are capillaries below, which continuously provide nourishment to hair and make it live beautifully!
What happens if the hair follicle is inflamed?
After hair follicle inflammation occurs, the inflammation will stimulate telangiectasia, hyperemia, swelling around the hair follicle, and pimples come.
Inflammation stimulates the nerve, and itching, tenderness comes.
Inflammation also stimulates the sebaceous glands to overproduce sebum, which is mixed with garbage, toxinsby pathogens. /strong>And cell corpses killed by inflammation, it becomes white or yellowish-white pus.
Papules develop into pustules when pus is not drained in time.
pustules rupture mostly in the epidermal layer of the skin, and damage to the epidermal layer generally does not leave scars strong>, so the folliculitis will not leave traces after recovery.
What’s up with the boils?
boils are caused by inflammation of the entire hair follicle, sebaceous glands and surrounding tissue.
Inflammation of a boil is wide and the infection is deep, causing more severe symptoms.
Head, neck, back and buttocks are where sebaceous glands are rich and secrete more sebum, making it easier to Grows bacteria, causing boils.
Interrupt a knowledge point:
Both sides of the quarrel and < strong>The triangle formed by the root of the nose is called the Danger triangle.
Here the subcutaneous blood vessels are more complex and even connect directly to blood vessels in the brain.
The boils here can easily lead to bacterial infection if squeezed by hand. If bacteria enter the brain through blood, it may cause intracranial infection, which is quite dangerous.
Who is the killer of folliculitis?
Mainly microbes such as bacteria, viruses, fungi. Among them, the most common pathogen is Staphylococcus aureus.
Many microorganisms live on the surface of our skin.
The general reputation is called “Common bacteria“, such as Staphylococcus epidermidis, Bacillus diphtheriae, Candida albicans, etc.
Those with a bad reputation are called “harmful bacteria“, such as Staphylococcus aureus, Proteus, Escherichia coli, etc.
Under normal circumstances, the skin protects itself by three moves.
The first trick, The surface of the skin is weakly acidic, which is not conducive to the growth and reproduction of certain microorganisms.
Second measure, The stratum corneum often falls off, which can remove some parasitic microorganisms.
The third trick, antibacterial peptides on the surface of the skin, can directly kill bacteria, viruses, fungi and other microorganisms.
However, if the number of “harmful bacteria” surges and infects hair follicles, hair follicle inflammation will come.
If the inflammation affects the hair follicles deep enough and the inflammation is large enough, boils and carbuncles are developed .
