Laser Treatments in Dermatology

Laser (Light Amplification by the Stimulated Emission of Radiation) devices used in dermatological treatments; They are light sources of different wavelengths that aim to damage the target cells and thus destroy the target without damaging the surrounding tissue. The wavelength of each laser depends on its active environment: Solid medium; Ruby, alexandrite Liquid medium; Argon or CO2 (carbon dioxide laser) Gas medium; Pulse dye Semiconductor medium; Diode laser.

What effect does laser light have on tissue?

When laser light encounters tissue, the light can be scattered in three ways:

• passes the target
• reflects from the target
• can be absorbed inside the target.

Laser creates three reactions in the tissue:

1. Photothermolysis effect: It causes an increase in temperature, thermal damage and tissue destruction in the target tissue. For this, the energy must be sufficient to cause heat damage, light at a wavelength that can be specifically absorbed by the target tissue, and the current duration must be short enough to cause damage only to the target tissue.
2. Photoacoustic effect: The absorbed light energy creates shock waves and causes vibration and fragmentation in the tissue. Expansion and intense local warming occur in the tissue and reconstruction begins in the skin.
3. Photochemical effect: There is an increase in heat in the tissue by absorption in the target tissue. This creates a chemical change in the rings in the color cells.

Which skin problems are treated with laser?

Facial capillaries, photodamaged, skin rejuvenation and rejuvenation, congenital vascular moles, freckles, postpartum spots, tattoo removal, epilation are the most common areas of laser use. Acne, vitiligo, psoriasis, keloid and scars are also included in laser treatment areas.

Different laser devices and usage areas

The wavelength, pulse duration and active environment of each laser are different. Laser should be selected according to the lesion and problem. Not every laser is suitable for every problem.

Laser Types

1. KTP Laser is effective in both vascular lesions (capillary dilation, strawberry moles) and superficial pigmented lesions (lentigo, freckle)
2. PLD Laser is effective in the treatment of vascular lesions, capillary vascular dilation, red vascular rose disease, various congenital moles and keloids.
3. Diode Laser is one of the most used lasers. The primary use is epilation. Diodes with a wavelength of 1450 nm treat fine cigarette lines nonablatively.
4. Alexandride Laser is another laser that is used most often. Those with a wavelength of 755 nm are applied for epilation. Those with a wavelength of 755 nm with a Q switch are an effective laser for blue, black and green tattoos.
5. Nd Yag Laser These are lasers sensitive to skin color cells called melanin. Long pulse 3-100 ms, 1064 nm wavelength Nd Yag laser; It is used for epilation purposes especially in people with dark skin, the procedure is painful than other epilation lasers. It is also used in vascular lesions, capillary vascular dilation and varicose veins. Q switched Nd Yag laser; It has a wavelength of 1064 nm, a pulse duration of 5-10 ns. It is especially used in blue and black colored tattoo removal. Mid infrared Nd Yag laser; It has a wavelength of 1320 nm and a pulse duration of 20-50 ms. It creates a relative dermal structure and is used in skin rejuvenation.
6. Er Yag Laser is a laser with a wavelength of 2940 nm, pulse duration of 0.1-3 ms, emitting invisible light. It creates less heat damage as it is more selectively absorbed by the water in the tissue. It causes limited and superficial heat damage to the surrounding tissue. It has a more photomechanical effect. The ablation effect is more controlled. It is used for the treatment of mild and moderate superficial wrinkles and remodeling. CO2 is better tolerated than laser. It can be applied more easily to areas where the skin is thinner and where Co2 laser cannot be applied, such as the eyelid, neck, back of the neck and hand, back. Pigmentation disorders, acne scars, xantelezma (local fat deposits), flat warts are other areas of use.7. CO2 Laser Sun damage is used in skin rejuvenation, fine wrinkle treatment, increasing skin tension. It causes heat damage in the upper and middle layers of the skin (epidermis and papillary dermis).
