Scars – Signs, Causes, & Treatment


The body’s recovery process results in the formation of scars. To fill up gaps created by an accident and repair damaged skin, your body produces tissue. Scars can be any size and form. They can arise due to infections, injuries, surgeries, acne, and accidents. The majority of scars disappear over time. Scars can be less apparent through a number of treatments.


A scar is the result of the body’s normal healing and replacement process for broken or damaged skin. Fibrous tissue frequently makes up scars. Scars can form for a number of reasons. These include infections, surgery, traumas, or tissue inflammation. Anywhere on the body, scars can develop, and their appearance might differ.

A scar may be colored, sunken, flat, or lumpy. It could itch or hurt. The ultimate appearance of a scar is influenced by a number of variables. These include the person’s age, nutritional state, skin type, where the scar is on the body, and the direction of the wound.


On lighter skin, a scar generally appears pink or red at first. The scar gradually changes from pink to a shade that is either slightly darker or paler than the surrounding skin.

Scars frequently appear as black blotches on persons with dark skin. Scars might itch, hurt, or feel uncomfortable at times. Several elements, such as the following, affect how a scar appears:

  • Injury or occasion, such as surgery, a burn, or severe acne, that results in the scar.
  • Dimensions, severity, and site of the wound.
  • Stitches or bandages are examples of the wound care you have.
  • Your ethnicity, age, genetics, and general health.

Causes of Scars

The scars are a normal aspect of the body’s recovery. Your skin serves as a barrier to shield you from bacteria and other toxic substances as a component of your immune system. The body produces new collagen-based tissue to help the skin heal after an injury.

Your body uses collagen for a variety of vital functions. These include skin hydration and joint protection through cartilage. Collagen fibers restore the skin’s damage and fit any openings when a scar forms. You are protected from infection by the new tissue.


Most scars are simple to identify on your own by keeping a watch on a wound-healed skin region. Scars may seem lighter, darker, or pinker than the adjacent skin. To assess a scar that is giving you trouble, your doctor will do a physical examination. To identify the type of scar, your physician will consider its size, texture, and color.

Treatments for Scars

Treatments might lessen the size or appearance of a scar. But the scar will never disappear entirely. Some medical procedures stop a scar from developing while an injury heals. Scar remedies comprise:


Dermabrasion, a popular method of treating acne scars, involves gently “sanding” the skin to remove the top layer of skin. The technique can make scars look less noticeable while softening and smoothing the skin.


Your doctor gives you an injection of medicine right into the scar to reduce its size and smooth it out. Injections of corticosteroids help minimize keloid scar size. Also, your doctor may provide medications intravenously to smooth scars and lessen itchiness and discomfort.

Laser Treatments

Numerous laser and light therapies can minimize the appearance of scars, including acne scars. In order to affect a certain action in the skin during laser treatments, there is a usage of a specific wavelength of light.

Additionally, if the scar is excessively thick or too thin, this movement could help it thicken or flatten. People with dark skin may have hyperpigmentation (skin darkening) or hypopigmentation (skin lightening) as a result of laser therapy. Before beginning therapy, discuss side effects with your healthcare professional.

Pressure Therapy

During the healing process, a wound is compressed by an elastic bandage, dressing, or stocking. The pressure either stops a scar from developing or reduces its size. Additionally, scar tissue can be broken up and rebuilt with the use of massage treatment.

Scar-Revision Surgery

A variety of surgical techniques can eliminate a scar, enhance its look, or perform a skin graft. This is a swap of one kind of scar for another, more aesthetically pleasing scar.

Topical Creams and Ointments

A scar may become less or not form at all by using silicone ointment. Alternatively, your doctor can advise using a silicone gel sheet or corticosteroid lotion on the affected region. Furthermore, if you have dark skin, talk to your doctor about using a hydroquinone-containing skin-lightening lotion to fade scars.

The Bottom Line

If you do not like the way a scar appears, talk to your doctor. A scar that troubles you does not have to be with you forever. Scars can be made flatter or less visible with a number of efficient treatments. Also, you might not even detect the scar at all after therapy.

Call your healthcare physician if a scar is making it painful or difficult for you to move. Treatments can ease pain and enhance mobility. Furthermore, always use sun protection on scars to lower your chance of developing skin cancer.
