Have you ever looked at an old scar on your body and thought, "Here it is again..."? Maybe it was a wound from childhood, or it could be a scar left after surgery. Living with these scars can be very difficult at times. They can change the way we look at ourselves, and they can affect our self -confidence. Some scars are located over a joint in the body, pulling the skin so tight that it is impossible to even bend or straighten the limb properly. So, there are several ways to reduce the appearance of these scars, among which laser treatment is something that many people are talking about. Let's take a look at this in detail.
Why do we really get scars?
Simply put, a scar is a mark left behind after an injury or damage to our skin. The nature of the scar varies depending on how deep and large the injury is.
Imagine that your skin is injured somewhere. At that moment, all your body's resources are directed to the injured area, trying to repair the damage as quickly as possible. It's like urgently building roads during a war. During this emergency repair, the body produces a special type of protein called collagen . Because these collagen fibers are produced quickly, they don't form in the orderly, smooth pattern that normal skin has. They form a little chaotically, quickly joining together to close the wound. That's why a scar looks different from normal skin.
These types of scars can have some effects on our lives. For example:
- Difficulty moving: Especially if the scar is over a joint like the knee or elbow, it may be difficult to bend or straighten the limb due to the lack of elasticity of the skin.
- Pain: Some scars can continue to cause pain long after the wound has completely healed.
- Itching: It is also common to constantly scratch the area around the scar.
- Concern about appearance: If you don't like the appearance of your scar, it can cause you a lot of stress and embarrassment.
What is Laser Scar Treatment?
Laser treatment is, to be precise, `laser skin resurfacing`. This method can reduce the appearance of wrinkles, dark spots, various skin problems, and scars. Surprisingly, this treatment can be successful even years after a scar has formed .
This is done in a doctor's office, not in a hospital. Your doctor will give you a local anesthetic , which is a medicine that numbs only the area being treated. You may also be given a medicine to take to reduce any anxiety or nervousness you may have.
During the treatment, high-energy light beams (lasers) are used to either remove scar tissue or create small holes in it. Both methods stimulate the production of new collagen . This allows the body to produce new, smoother skin. After treatment, your scars should be lighter and less visible.
But keep one thing in mind. Laser treatments cannot completely remove a scar 100%. What is really happening here is that instead of an old, visible scar, a new, smaller, less visible scar is created. Also, you may need to have several treatments to get the results you want.
How laser treatment works and types
There are two main types of laser treatments. Your dermatologist will determine which method is best for you based on the nature of your scar.
| Type of treatment | How it works and details |
|---|---|
| CO2 Laser Therapy | This involves removing thin layers of skin on the surface of the scar using a laser beam, minimizing damage to the surrounding skin. Only a small portion of the scar is treated at a time. Therefore, if the scar is large, several sessions may be required. It can take about two weeks to heal after this treatment. |
| Fractional Laser Therapy | Here, the laser beam goes deep into the skin and tightens the collagen fibers in the scar. This causes less damage to the skin, but because the laser goes deeper, there is a slight chance of additional scarring. The healing time is longer. It usually takes about a week to heal. |
If you're considering laser treatment, the first thing you should do is talk to a good dermatologist . He or she will examine your scars and recommend the best laser treatment for you.
What to expect after treatment?
After the laser treatment, a bandage is applied to the area. It should be left on for about 24 hours . After that, the area should be cleaned two to five times a day. This can be done with a saline solution or water with a little vinegar added. The doctor also recommends applying a healing ointment such as Aquaphor, Eucerin, or Vaseline. The main goal here is to prevent the wound from scabbing.
It usually takes between 5 and 21 days for the wound to heal. This depends on the type of treatment you received. Even after the wound heals, there may be some redness in the area for several months .
Are there any side effects to this treatment?
Yes, like all medical treatments, there are some possible side effects . There's nothing to worry about, but it's important to be aware of them.
- Cold Sores: If you have a history of cold sores, laser treatment may cause them to come back, especially around the mouth. Talk to your doctor about this in advance so he or she can give you antiviral medication before treatment.
- Milia: These are small white bumps that form on the skin. They are not serious, but they can be a bit unsightly. You can remove them with gentle exfoliation with a warm cloth. However, if that doesn't work, your doctor can easily remove them.
- Hyperpigmentation: Some people may experience some darkening of the skin in the treated area after treatment. If you are concerned about this, you can use a skin-lightening cream. Also, if you must go out in the sun after treatment, be sure to use a sunscreen with at least SPF 30 .
All things considered, laser treatment is a great option for reducing the appearance of scars. However, it is not a one-size-fits-all solution. Therefore, it is important to speak with a qualified doctor before making a decision and clearly understand how effective it is for your situation and what the risks are.
