Scarring: An Overview

Scars are a natural part of life in every sense of the word. Everyone has a scar– you included! So why do we get unsightly scars? And what can we do about these skin conditions? 

Scars are a part of the body that indicates the location of an original wound. When the body attempts to regenerate tissue, replacing the old, damaged tissue, a scar results.


Scars are a natural part of healing--when an injury heals, a scar is a physical result. 

Scars vary in appearance based on the cause of the wound. Large scars can cause anxiety, depression, and distress. There are mental health effects to scarring because the scarred individual often feels uncomfortable with the disfiguring nature of the scars. 

However, it is important to remember that scarring is a natural process, and there are things you can do to prevent scars.

Continue reading for everything you ever wanted to know about scars, including how to get rid of them, once and for all. 

What causes scarring?

Injuries to the tissue cause scarring. The chance of scarring increases with improper wound care during the wound healing process. For example, if a wound is not cleaned or covered during wound healing, the chances of scar formation increase. Scars occur when the body attempts to repair itself with increased collagen production. If inadequate wound care or covering happens, scar formation is more likely. 

What is scarring in the body?

A scar is a natural process that happens when the body heals an injury by increasing collagen production to the area in question. Collagen production in the dermis increases where skin injury is present to help heal and strengthen the tissue. Scarring in the body is the natural process of the body healing itself.  

Types of Scars

There are numerous types of scars with varying causes and severity. Chickenpox, acne, piercing, and vaccination can cause scars.

Scars are part of your body’s natural healing process and are a mechanism of tissue restoration.

Post-surgical scars

As implied by the name, post-surgical scars result from incisions of surgical procedures. Every invasive surgery results in some type of scar. Scar formation following surgery occurs in multiple stages. 

  1. Immediately after a surgeon closes a wound, the body reacts through clotting-- this occurs for a week after surgical procedures.
  1. Next, fibrous tissue forms from collagen and elastin in the dermis. The amount of collagen production informs the size of the scar. 
  1. Finally, a lower layer of the skin reconstructs and heals, regenerating tissue with a lighter, softer, less sensitive tissue in place of the old. 

Acne scars

Acne scars often come from a pimple that pops prematurely. Severe pimples or acne can result in pitted scars. Pitted scars appear to be a dent in the skin. A dented skin is also known as an atrophic scar. Atrophic acne scars occur when the body is not able to regenerate skin. 

Stretch marks

Stretch Marks come from weight changes due to pregnancy or weight gain. When the body gains weight quickly, the skin stretches out, and the body reacts. The result is stretch marks, a form of scars. 

Keloid Scars

Keloids are an overgrowth of tissue when collagen continues to produce after an injury heals. This results in raised scars which eventually flatten when collagen production slows down.

Hypertrophic Scars

Hypertrophic scars resemble keloid scars but do not grow beyond the boundaries of the injury. A hypertrophic scar features an overgrowth in collagen that eventually stops growing. 

Types of Scar Treatments

There are different types of scar treatments, each with circumstances that application is most successful.

Topical silicone gel or silicone gel sheets

The main ingredient in silicone gel sheets is silicone which protects the scar from bacteria-induced collagen. Silicone gel also regulates fibroblast production which reduces collagen and results in a flatter scar. 

Pressure dressings

Some patients apply pressure to the scar using a specially formulated tool that compresses the scar. Pressure devices are useful for four to six months with unclear results. 


Steroid injection occurs into scar tissue, reducing itching, burning, and shrinking the appearance of a scar. 

Skin camouflage (makeup)

Skin camouflage via makeup does not reduce the inflammation from a scar-- it merely masks the problem. Some people wish to camouflage a scar while it heals, hiding the appearance as much as possible. 


Surgery can occur on keloid and hypertrophic scars that are severe. This option is not extremely popular as keloid regrowth can occur. Scar revision surgery reopens a wound and alters the shape of a scar.

Laser Therapy

There are different kinds of laser therapy treatments that can flatten skin and remove discoloration present in scars. A pulsed dye laser is a form of laser resurfacing that reduces the appearance of scars. Laser resurfacing flattens the skin, minimizing scars. 


This dermabrasion process removes a thin layer of skin and is good for fine lines, minor scars, wrinkles, and age spots. A dermatologist can do dermabrasion treatments.

How to Care For a Scar

The best way to care for a scar is to practice excellent wound care. Effective wound care means keeping a wound clean and dressing it properly. Wound care protects existing scabs and reduces the chances of reinjury. If a scar is already present, keep it out of the sun. Another scar care tip is to keep the area moist so it does not harden. 

Preventative care will stop a wound from turning into a scar, and scar management care will reduce the appearance of a scar. 

Best Ingredients for Scar Care

The best ingredients for scar care vary based on the type of scar. For example, retinoids and hyaluronic acid are typical ingredients for stretch marks scar care. Retinoids reduce fine lines and the appearance of scars. Hyaluronic acid is a common ingredient in skincare that promotes collagen production, the regeneration of skin, and scar reduction.

Vitamin E and cocoa butter are additions to scar care products for their moisturizing and repairing abilities. 

How Do Over The Counter Scar Care Products Work

Most over-the-counter scar care products contain a topical antibiotic, wound irrigants, and wound antiseptic. Topical antibiotics and wound antiseptics reduce the chance of infection and minimize the risk of a scar. Wound irrigants flush out the injury, leaving it less susceptible to infection.
