If you think lasers are nothing but a harmful technology as seen in movies such as Star Wars, you can be mistaken about it, too. While contemporary technology says we are getting advanced by the day, we’re never as nearer as that portrayed in the movies. This means that, unlike what are seen in the movies, laser weapons are not yet existent but are used into something more beneficial. In reality, lasers are not just for Jedi Knights but for people who have more practical use of them. One of them, being, are dermatologists.
Dermatologists are people who specializes in matters pertaining to the hair and skin. Common use of lasers by dermatologists ranges from the removal of tattoos to that of fine lines or wrinkles. Almost similar to Botox, treatments with the use of lasers are considered as almost ubiquitous due to tis versatility and fast results. According to Robert Anolik, a dermatologist from New York, “[use of laser treatments is] one of the fastest-growing services in-office.” The American Society for Dermatologic Surgery even stated that in 2012, two million laser treatments were performed and has been lightning fast since.
What is a “Laser” and How Does It Works?
The word “laser” is actually an acronym in itself which comprises the words: “light amplification by the stimulated emission of radiation.” Tina Alster, director of the Washington Institute of Dermatologic Laser Surgery, described laser as “a device that focuses light energy onto a specific area.” “For a dermatologist, that means targeting and obliterating something specific in the skin, such as water or pigment.”
There are many lasers developed through the years, but each of which falls only into two categories: traditional and fractional. Within fractional category is another subset of categories namely: ablative and non-ablative. Roy Geronemus, a dermatologist from New York, describes fractional lasers in non-scientific sense as “like pixelation in a digital image.” Unlike fractional lasers, traditional lasers have more concentrated ray of light on one spot which may only take fewer sessions than a fractional laser would.
Hair and Skin Problems Treatment from Lasers
While no one else knows better how laser treatment works than the dermatologist himself, the following are some of the common skin problems it treats:
- Lines and wrinkles
- Broken Blood Vessels, Facial Redness, Spider Veins, or (Red) Vascular Birthmarks
- Brown Spots or Birthmarks
- Acne scarring
Common laser treatments can be expensive whose cost ranges from a few hundreds of dollars to several thousands. Although at-home laser products exist to remedy this problem in the long run, they are not as effective but are nonetheless better than topical products.
