Types of lasers for skin treatment
What is a Laser?
A laser is a device that can amplify and concentrate a particular wavelength of light. This increases the energy and permeability of light waves.
What are the uses of skin lasers?
Skin laser devices use the energy of light waves for a variety of purposes, including:
- Wrinkle removal, rejuvenation, superficial and deep exfoliation and facial skin lifting
- Excessive facial and body hair removal
- Removing skin stains, freckles and some stains from pregnancy
- Removing acne, pimples and scars and removing tattoos
- Stretch Marks for Pregnancy and Weight Loss
- Treatment of vascular lesions, hoarseness, varicose veins and mole removal
What are the Important Points in Using Laser for Skin?
Most used lasers for skin therapy:
Carbon Dioxide Laser (CO2): This laser is one of the oldest and most used laser devices that is used for removal of moles, warts and all skin lesions due to its high energy. This laser can be used for deep skin peeling, lifting and wound healing. A newer type of laser, known as Fractional CO2, is used to treat refractory stains, skin cracks, pores and scars.
Erbium Laser: The laser is most used in skin rejuvenation because it can remove a very thin layer of skin. It is therefore suitable for exfoliation, removing delicate wrinkles and treatment for superficial pimples.
Nd: Yag Laser: Most commonly used for color changes and skin patches, subcutaneous veins such as varicose veins and tattoo removal. This laser is also used to remove unwanted hair.
Alexandrite Laser: Although it is mainly used for hair removal, Alexandrite laser can be used to remove tattoos and other skin spots.
Who is not suitable for laser treatment?
Young people still in the active phase of pimples (acne), people with very dark skin (due to excessive skin pigmentation and the risk of post-laser skin discoloration) and people with skin diseases such as psoriasis and lupus and by stimulating their skin they may relapse. These people are not good candidates for laser skin care.
What are the possible complications after a laser?
Complications can include burning, itching, redness, swelling and pain in the laser area. These complications are mitigated if care is taken after laser treatment, including ice pack placement and anti-inflammatory ointments application (where appropriate). More severe complications, such as infection at the site of operation, swelling of the lymph nodes in the area, and scarring are usually caused by the therapist’s inadequacy or inappropriate use of the device.
