Scar Laser Treatment - Revitalize Your Skin

Scars can be caused for various reasons, e.g. chemical and thermal burns. Scars can occur in different places, e.g. after acne.

Fractional CO-2 laser is a well-documented treatment for all types of scars. The CO-2 laser has proven to be the best for scar treatment and skin tightening.

The formation of scar tissue is a natural bodily response to a skin injury. With most deep wounds there will be some degree of scarring, and a number of different scars can develop after operations, trauma and inflammatory processes in the skin.

Scars are not harmful and do not require removal for medical reasons. However, they can be painful, itchy, limiting and have a significant psychological effect on a person, prompting patients to seek treatment. With laser and light-based technologies available today, increasing evidence shows the effectiveness of these treatments in improving various types of scars, including keloids, hypertrophic scars, atrophic scars, and acne scars.

Laser scar therapy

Laser scar therapy uses photothermal energy to target intra- and extracellular structures in the scar tissue to improve color, and also stimulate the process of neocollagenesis and dermal remodeling. Rarely can a scar be completely removed using these methods, instead the aim is to reduce the appearance of the scar and any discomfort caused mentally, physically and cosmetically.

Types of lasers for scar treatment

Different types of lasers have been used in the treatment of scars for a number of years, including CO2, Nd:YAG, Pulse Dye and Er:YAG lasers. Lasers are chosen based on the severity of the scar, the patient’s skin type and work. according to the theory of selective photothermolysis. Most recently, fractional photothermolysis with ablative and non-ablative fractional lasers has found use as effective treatments for scars.

The difference between ablative and non-ablative lasers The differences between ablative and non-ablative lasers as well as fractional and non-fractional delivery are based on the basic process of the target chromophore, photothermolysis, and how the energy is delivered to the target area.

Ablative lasers are highly absorbed by water and cause the removal of material from the surface of the skin by evaporation. In comparison, non-ablative lasers reach temperatures in the tissue to induce vaporization, and as such do not remove material. Instead, they deliver a controlled zone of thermal damage through epidermal and dermal heating.

Fractional laser

Both non-ablative and ablative lasers can be administered via a fractionated delivery system, meaning that the laser beam is divided into a number of microscopic laser beams that are much smaller in size than the original full beam. This fractional delivery can be produced in a number of ways, most commonly via a microlens array or a fractional scanner.

What causes scarring?

Excessive traction or tension on a healing wound is a factor that can increase inflammation and scarring, and if healing is delayed, for example due to infection, this will increase the risk of connective tissue build-up, resulting in an increased likelihood of scarring.

The main difference between scar tissue and normal skin is the amount of collagen it contains and the way the collagen fibers are produced. The elongated collagen fibers are well arranged in normal skin. The structure of collagen fibers in scars, on the other hand, is disorganized and markedly different from the normal surrounding tissue. The collagen fibers become more tightly packed and more resistant to elimination by the natural enzymes released by the body as the scar ages.

The degree of scarring, including the size and depth of the wound, the blood supply to the region, the thickness and color of the skin, and the direction of the scar, can be affected by several variables. The age of individuals also significantly affects the development of scars. Younger skin, for example, appears to overheal, resulting in larger, darker scars compared to older skin. In addition, the position of the body where the wound takes place can affect the appearance of the scar, with the sternum being particularly prone to scarring.
