We all have a small scar somewhere on our bodies, right? Maybe it's a scrape on our knee when we were kids playing. Or maybe it's a scar from cutting our hand with a knife while working in the kitchen. For some people, the scars on their faces caused by acne are a big part of our lives. But some scars can be just as annoying as they are beautiful. So today, let's talk about what scars are, how they form, and what can be done about them.
First, let's see what a scar is.
Simply put, a scar is a mark left behind by a wound on our skin that has healed. Imagine if your skin gets cut, scraped, burned, or otherwise damaged, our body's amazing healing mechanism kicks in. During this process, the body creates new tissue to close the wound. This new tissue is mainly made up of a protein called collagen .
These scars can come in all shapes and sizes. Some scars fade over time and become barely noticeable. But some scars can be large and painful.
In particular, people with dark skin (such as Africans and Asians) and red hair are more likely to develop a type of scar called a keloid . These are not like regular scars, but rather a type of scar that grows beyond the area of the wound and is raised above the skin. Sometimes, depending on where these scars are located, it can be difficult to even move the body.
But remember, not all scars need treatment. Many will fade on their own over time. But if one of your scars is bothering you or causing you pain, there are treatments that can be done.
What does a scar look like? What factors affect it?
Usually, a scar on light-colored skin will initially appear pink or red. Over time, this pink color fades, and the scar will become slightly darker or lighter than the surrounding skin. For people with darker skin, scars often appear as dark spots. Sometimes scars itch, and may be painful or tender.
Several factors determine the appearance of a scar.
- The cause of the scar: That is, what caused it, such as surgery, a burn, or severe acne.
- Size and severity of the wound: How big and how deep the wound is is also important.
- The treatment received for the wound: Whether the wound was stitched or simply bandaged with medication affects the way the scar forms.
- Your age, genes, and overall health: All of these affect how a scar forms and heals.
Are there different types of scars?
Yes, there are actually different types of scars. Knowing which type your scar belongs to makes it easier to choose the right treatment for it.
| Type of Scar | A simple description about it |
|---|---|
| Contracture | These are most often caused by burns. The skin loses its elasticity, becomes tight, and becomes wrinkled. If they affect joints, muscles, or nerves, they can even make it difficult to move. |
| Depressed/Atrophic scars | These are often caused by chickenpox or acne. They look like small pits on the surface of the skin. They are most commonly seen on the face. As we age, collagen in the skin decreases, making these scars more visible. |
| Flat scars (Flat) | These may be slightly raised at first, but as they heal, they flatten out to the same level as the skin. They may be pink or red at first, but later become slightly lighter or darker than the surrounding skin. |
| Keloids | These are the scars mentioned earlier, which protrude from the skin and grow beyond the wound . Sometimes these can become very large and can interfere with movement. |
| Raised/Hypertrophic scars | If you run your finger over these scars, you will feel them well. Although they are raised above the skin, they may shrink a little over time. But they will not become completely flat. They will not extend beyond the wound like keloid scars. |
| Stretch marks | When the skin is suddenly stretched (for example, during pregnancy, when you suddenly gain or lose weight), the connective tissue underneath the skin is damaged. This is why these scars form. They are most commonly seen on the breasts, stomach, thighs, and upper arms. |
What treatments can be done for scars?
If your scar is bothering you emotionally or physically, there are several treatments that can help reduce or make it less noticeable. But there's one thing to remember.
Although treatments can reduce the appearance of a scar, they cannot completely remove it 100%.
Your doctor will recommend the most suitable treatment for you based on factors such as the type, size, location, and age of your scar.
- Dermabrasion: A procedure used specifically for acne scars. This involves using a special device to gently remove the top layer of skin. This smoothes the skin and reduces the appearance of scars.
- Injections: Injecting medication directly into the scar can help shrink and flatten it. Corticosteroid injections are used, especially for keloid scars.
- Laser treatments: Advanced laser technology can significantly reduce the appearance of scars, especially acne scars. Different types of lasers can reduce the redness/pinkness of the scar and break down scar tissue. This can also reduce pain and itching.
- Pressure therapy: Wearing an elastic bandage, garment, or sock that applies pressure to the wound while it heals can help prevent scarring or reduce the size of a scar that has already formed.
- Scar-revision surgery: In some cases, surgery can be performed to remove the scar and create a more visible scar. Sometimes, a skin graft can be performed using skin from another part of the body.
- Topical creams and ointments: Applying gels or ointments containing silicone can help reduce the appearance of scars. Sometimes your doctor may also recommend a cream containing a corticosteroid. There are also creams containing hydroquinone to lighten dark scars, but these should only be used under medical advice.
What can you do to prevent a wound from becoming a scar?
We can't always prevent injuries, but there are a few things we can do to prevent them from becoming a big scar once they occur.
- See a doctor: If you have a wound that looks like it could leave a scar (such as a deep cut), see a doctor right away. You may need stitches or special bandages. Stitches help hold the two sides of the wound together and heal, minimizing scarring.
- Keep the wound clean: Wash the wound thoroughly with soap and water. Clean off any dirt, dust, or dried blood. Cover the wound with a clean bandage to prevent germs from entering.
- Keep the wound moist: Drying out the wound and forming a large crust can lead to scarring. Therefore, it is important to keep the wound moist by applying something like petroleum jelly. However, consult your doctor about this.
- Protect yourself from the sun: Sunlight can darken a scar, so keep it covered with clothing or wear sunscreen .
- Get good nutrition: Vitamin C and vitamin D deficiencies can affect wound healing and scarring. Also, protein is essential for skin regeneration. Therefore, it is very important to eat a well-balanced diet.
When should you see a doctor about a scar?
A scar is usually nothing to worry about. However, it is important to see a doctor in the following cases:
- If you are concerned about the appearance of your scar.
- If the scar is painful, itchy, or feels different.
- If the scar is difficult to move.
- If you notice a new spot or mole near a scar (this could be a sign of skin cancer, so it's important to get it checked out right away).
- If you have a tendency to develop keloid scars, talk to your doctor before getting ear piercings, tattoos, or other surgery.
