Laser Treatments: A Revolutionary Technology
In the last several decades, laser treatments have emerged as a revolutionary new technology that is solving all kinds of problems. Laser can even be used to treat skin situations, such as acne, scars, birthmarks, or wrinkles.
What Is Laser Treatment?
The word “laser” actually began as an acronym for “light amplification by stimulated emission of radiation”. Laser is a very focused kind of light that is tuned to specific wavelengths. Depending on the intensity of its focus, it can be powerful enough to cut steel and diamonds. It’s extremely precise and causes decreased levels of scarring, swelling, and pain.
What Does a Laser Treatment Treat?
Laser treatments are used to address a myriad of medical conditions. They’ve been utilized to remove tumors, precancerous growths, polyps, and kidney stones. Laser therapy can repair detached retinas; improve vision with LASIK eye surgery; and seal blood vessels, nerve endings, and lymph vessels to reduce pain, bleeding, and the spreading of cancerous cells.
Cosmetically, laser is used to resurface the skin. These laser resurfacing treatments are applied to scars, blemishes, and wrinkles, to reduce their appearance. Blemishes, such as moles, warts, sunspots, birthmarks, unwanted hair, and tattoos, can be removed with laser treatments.
How Is a Laser Treatment Done?
Laser procedures vary, depending on the type of medical treatment that is being performed. For tumors, doctors often use an endoscope, a thin lighted tube, that is inserted through an opening in the body and placed beside the tumor. The laser light is then aimed at the offending cells to shrink or destroy them. Sometimes, photodynamic therapy (PDT) drugs are used. The patient is given a PDT injection. After one to three days, the drug mostly remains only in cancerous cells. Then, laser treatment is applied, causing the photosensitizer to produce an active oxygen that destroys cancer cells.
In cosmetic procedures, laser resurfacing removes the outer layer of the skin and heat activates the lower level of the skin. This encourages the skin to produce collagen and to grow a new layer of skin that is free of wrinkles and blemishes. The results may vary, depending on the situation and the patient. Wrinkles respond well to laser treatment. Birthmarks, such as port-wine stains, may require more than one treatment. Acne scars should experience some improvement.
Laser technology is giving many people the chance to resolve skin and medical conditions that were previously untreatable. Consider laser treatment for your situation. You may be surprised at the results.
