Why do scars never Fade?

Our body is strong. But everything has a stage, where it just can’t. This is when bruises and scars form. When our body tries to heal itself.But how exactly does our body heal itself….?

  •  The Healing process

 Now, your skin consists of some hardened cells which are called keratinocytes. These are the cells which shed constantly. In fact it is said that throughout your life, you shed about 18 kgs of skin cells! Now, imagine that you’ve gotten  a wound. Let’s say it was pretty deep. What’s the first thing you notice? Well, bleeding of course. The first stage through which your body recognises that you’ve been hurt is hemostasis. Hemostasis is our body’ s response from losing blood and the epidermis being compromised.Your blood vessels start to shrink themselves from further bleeding. This process is also known as vasoconstriction. The fibrin starts to make the cross link patterns,  also making the germs  not enter  the inside of the body .Hemostasis basically  means stopping the flow  of blood. The second step is inflammation. Now the wound may redden, swell up or hurt. This can vary from  person to another, maybe due to the difference in genetics of the cells. During this process, WBCs come towards the wound, killing the germs or pathogens which may have entered while the wound was still open. It also eats up the damaged tissue. This  process has a name. It is called Phagocytosis. As the WBCs travel through the bloodstream to reach the site of injury,the the ,the shrunken blood vessels, now expand a bit. After some point of time, the proliferative stage- where the fibroblasts come into the scene. These fibroblasts are the one which produce collagen. Collagen is a protein which is a primary tissue. These usually form a certain kind of  pattern. But, immediate cure is needed when you are wounded. They are deposited as soon as possible. They initially replace the work of the fibrin. Slowly, but steadily,the epidermis layer closes. The hardened RBCs get peeled off in due course of time. It is believed that  the skin is never fully recovered. In some minor cases, the scar eventually fades and works normally, but when the wound is severe, meaning the wound makes  contact with the dermis(the second layer of the skin) then , maybe it leaves a dark line or a pale mark. In the most severe cases, for example, the major burn cases, the skin never quite recovers. Sure it retains its sensory 

properties ,but the skin no longer remains the same. 

This is why you must have noticed, wherever there is a scar, there grows no hair. 

  • Types Of Scars

There is a differentiation between scars as well. Basically, there are 4 types of scars.Let’s see them!

  1. Keloids-  When you get a wound, and the scar formed is bigger than your actual injury, then that scar would be termed as keloid scar. These are usually due something called the ‘overproduction of cells’, according to a site. These are usually treated with surgeries, laser treatments etc. This scar is more common with the darker skin tones.
  2. Hypertrophic scars- When you get an injury ,and the affected skin rises above or swells, this red scar is named as ‘Hypertrophic scars. 
  3. Contracture scars- These type  scars occur after a burn. They include tightening of skin and sometimes, the scars may even go into the nerves or muscles.
  4. Acne scars- Many acnes leaves scar. These scars can sometimes be quite deep, but not usually.
  • Difference Between bruise and scar

When you hit something, one says that it will leave a bruise. The bruise turns purple due to lack of oxygen. A bruise is never permanent and eventually fades away. Bruises are more common than scars.

When one experiences severe wounds, usually tending to bleed excessively, this usually leads to a scar. Scars may or may not be permanent. A deep injury may gradually heal but rarely fades away and is usually permanent.

Scientists  fully do not know how exactly our body heals itself. Various researchers are working hard to break the code on how and what processes does our body use to heal itself. In fact we don’t even know how a deer is able to completely heal itself from the most severe scars completely whereas a human being is not. The mysteries are endless. We haven’t even cracked ⅓ of the nature’s  pecicular happening , but do not worry, the day will come soon!

Many people think that scars are not pleasurable. But let me tell, there are people out there suffering with diseases which include the body losing its property to heal and regenerate itself. Even a small bleeding does not stop. Scars define how strong your body is to heal it so efficiently. Never be ashamed of your scars. Because they are a part of you. And you never neglect a part of you. Be proud that you survived that injury. A scar speaks for itself. Even if the scar was due to some silly mistake. None of us are Harry Potter to have a deep reason behind a scar and that scar will always be pretty( though one can dream right?).
