Laser treatment of scars

A scar is a derivative of tough fibrous connective tissue formed after trauma to the skin. Before choosing the method and duration of scar treatment, it is important to know the type of scar.

Normotrophic scars do not cause great regret for patients. Such scars are at the same level with the skin surface, their color and elasticity are very close to the skin.

For the treatment of normotrophic scars, long-pulse ND: Yag, ER: Yag, and CO2 lasers are used to synthesize collagen, ER: Yag, and CO2 lasers are used to smooth the scar surface, and dye-based laser PDL and long-pulse ND: Yag laser are used to eliminate small capillaries on the surface of the scar. is being

Atrophic scars are mainly caused after acne or as a result of poor treatment of spots and papillomas. Stretch marks (stretch marks) are also considered atrophic scars. Atrophic scars are lower than the skin line, they become wrinkled due to the reduction of collagen synthesis. For this reason, depressions that create a cosmetic defect are formed in the scar area.

In the treatment of atrophic scars, mainly long-pulse ND: Yag laser, ER: Yag and CO2 lasers for the synthesis of collagen, ER: Yag and CO2 lasers for polishing the edges of the scar, and dye-based laser PDL and long-pulse ND:Yag laser to eliminate small capillaries on the surface of the scar is used.

Hypertrophic scars are pink in color, above the skin surface. Such scars can disappear freely within a few years. Because they are easy to treat, it is not worth waiting for them to disappear on their own for a long time.

In the treatment of hypertrophic scars, collagen synthesis is prohibited, but ER:Yag and CO2 lasers are used to smooth the scar surface, and dye-based laser PDL is used to eliminate small capillaries on the scar surface.

Another type of hypertrophic scars is keloid scars. Keloid scars are raised on the skin surface. In most cases, there is a burning and itching sensation. This type of scars is difficult to treat, often relapses and has an aggressive course.

In some cases, only the ER:Yag laser can be used to treat keloid scars.
