Comparing Laser Technology

Laser skin resurfacing has long had the promise of providing people with younger, fresher-complected skin, but, like deep chemical peels, it had a major disadvantage: the treatment worked by ablating (vaporizing) the skin so it could be painful, even temporarily disabling, and required many weeks to fully heal. Recently, the old CO2 lasers have been replaced with more skin-friendly lasers, such as the Erbium-YAG laser, which has reduced the healing time, although it remains considerable.

To avoid the long recovery time, many cosmetic surgeons are moving to systems such as the Intense Pulsed-Light (IPL) system or the BroadBand Light (BBL) system that are non-ablative. They work by a process known as selective photothermolysis, in which darker components of the skin surface–such as age spots, rosacea and hair–suffer damage preferentially, leaving lighter components more intact. Unfortunately, these systems are so non-invasive that they require many treatments to give even the moderate results they achieve, although they are more effective on some problems (such as rosacea) than lasers.

A more recent technology has been developed that promises many of the results of ablative laser treatments, without the necessary healing time, and also in fewer treatments than IPL, BBL, or other non-ablative treatments. Fraxel Laser Treatment promises great results with little pain or down-time, but does it work?

What is Fraxel?

Fraxel is the trade name for a version of laser treatment that compromises between ablative and non-ablative techniques. The name stands for “fractional laser” treatment, and in the technique, a laser is used to ablate micro-columns of skin as deep or deeper than traditional laser resurfacing. These micro-columns are distributed evenly across the surface of your skin by the computer-controlled laser so there is not significant damage to any one part of the skin. However, on a microscopic scale, each column of ablation stimulates the skin to heal itself, leading to a rejuvenation in the skin.

What does Fraxel Treat?

Fraxel has been approved by the FDA to treat:

• Periorbital wrinkles (wrinkles around the eyes)

• Pigmented lesions (age spots, sun spots, freckles, etc.)

• Melasma

• Acne and surgical scars

In addition, the company’s manufacturer claims that it can treat:

• Poor skin tone

• Large skin pores

• Rejuvenate skin in the neck, chest, and hands

Although clinical studies on Fraxel seem to be limited to doctors with a stake in proving the effectiveness of the procedure, so far the data suggests that Fraxel can successfully address many of the claimed issues.

Relative Effectiveness of Fraxel vs. Other Treatments

Fraxel seems to be a much more effective treatment than other options for acne scars and periorbital wrinkles. It can also be effective in treating some cases of pigmented lesions, depending on the color of the lesion.

However, for the improvement of skin tone, it is probably not as effective as full skin resurfacing.

And BBL and IPL are more effective at treated red skin conditions, as well as for hair removal.

  • My Pains, My Chiropractor

    Having low back pains has made me very familiar with Chiropractors.  As a health care discipline and profession, it emphasizes diagnosis, treatment and prevention of medical disorders of the musculoskeletal system, especially the spine thus I usually run to my Nashville chiropractor for my pains. 
    As the third largest health profession, behind medicine and dentistry, chiropractic care for low back pains became common. With their license, practitioners in the field are reliable enough given the education and training they obtained. 
    My Chiropractor has been taking care of me for ages now and without his help, I would not be able to function properly nor write this blog post without pain. So, if you even need chiropractic care, do your research because getting a good chiropractor may just be your saving grace too. 

    The Unexpected Benefits of a Good Colon Cleanse!

    Why are so many people looking for the perfect colon cleanse? Given all of our unhealthy diets and unhealthy lifestyles, colon cleansing is a great way to regulate and improve the function of the colon. A regular colon cleanse is also helpful in preventing constipation. A good colon cleanser, coupled with a healthy diet rich in fibers gets rid of undigested waste as well as the hardened fecal mater that is blocking the passageway of the colon. Waste has no problem passing through the intestinal organs, preventing constipation.

    There are many benefits associated with colon cleansers, but perhaps one that people do not expect is the significant weight loss that may come with it. The average colon weighs at about 4 pounds, but it has the amazing ability to store up to 30 pounds of fecal matter. Once the colon is rid of this, it is only natural for a person's weight to go down too!

The best solution is still to go with something natural, which poses less threat to side effects.

    Good Quality Water Damage Cleanup Services are not Optional

    If you’ve ever experienced a blown pipe, then you already know how much damage it can do to your home. It happened to me recently and I was unfortunately not home at the time. By the time I got home, the water damage was unbelievable. I lost a lot of items, including books that I’ve had for a long time and really treasured. It was hard to believe that all that damage could come from just one blown pipe. I didn’t know where to start with the water damage cleanup. My carpets were an unbelievable mess and after just a few hours, I could see mold starting to form on my wooden furniture. It’s a good thing that the same thing had happened to someone from work who gave me a number for a water damage Orlando restoration company that he had already tried before. They offered a 24 hour service which was great since I didn’t get around to calling them until pretty late at night. They gave me a free phone consultation and threw in a free visual inspection too. They got my house back to normal in a lot less time than I could have hoped for. They also cleaned my carpets and they look pretty great now. I’m glad that I got the number of a reliable restoration company when I needed it. Hopefully, this will never happen to me again but in case it does, I’ll at least have a number that I can call to help me get back on my feet.
