I want to spend some time discussing lasers and how we use them today.  Lasers have been around for some time.  In the past, at least as far as medicine is concerned, they have been a technology looking for an application.  In the past several years, improvements in technology have made them much safer and applications have greatly increased.

laser  Austin Powers....demonstrated his ignorance of laser technology.  Lasers have been a mystery to most!! 

Laser and intense light or flash lamp therapy are both based on concentrated light.  Let's talk about lasers first.

laser technology

Lasers are concentrated light that can be used for multiple applications.  They have been used in industrial applications for years. Medical lasers have numerous applications as well.  We use them to to clear up and make skin look prettier.  We use them to remove tattoo's.  They are used to treat veins and vascular problems on the body and face, even varicose veins.  We can remove unwanted hair, laser fat cells, make skin contract, use them to cut skin, and now we can treat toenail fungus which has been a nagging problem.

Pulsed light therapy is based on a bright flash of light shot onto the skin.  Also called a flash lamp, this technology has been used for other applications, photography, etc.  In cosmetic surgery we use it to treat spots and different pigments on the skin of the face or body.

Unfortunately, there is no single laser that can be used for all applications.  Not to get too complicated (because it is complicated) the way we choose what laser or lamp to used is based on the chromophore we are trying to treat.  A chromophore is the part of a molecule or cell that produces its color.  Each laser or flash lamp has a wave length that attacks that color.  This is why one laser or lamp will not work on all colors.  We know what colors we are trying to treat and select the laser or lamp that will work on that specific color.  This is where the art meets the science.  With some applications, we are aiming at water in the skin as the chromophore, especially when resurfacing the skin. 

The most common laser currently used in Cosmetic Surgery are the nd-YAG, the KTP, the CO2, and the pulsed dye lasers.  Each of these target a different chromophore or color.  The newest developments in the technology is the fractional and q-switched technologies.  We used to resurface skin by ablating or lasering the entire skin surface.  Since the skin recovers by healing from the hair follicle, recovery was slower than desired and this scared people.  Fractional lasers give us the ability to divide or fractionate the pulse of light from the laser.  This leaves islands of undamaged skin between the areas treated.  There are more and larger areas for the skin to heal.  The advantages are that healing is much faster and complication rates are less.  The disadvantages are that the treatment is not quite as good and may require more than a single session.  Q switching is a way to modulate the laser output to get a better "quality" of light energy, more intense output per pulse.  I will talk more about Q-switching when I discuss tattoo removal.

Flash lamps also treat specific colors in the skin.  They are used for treatment of brown pigment, red pigment, and hair in the treatment areas.  With flash lamps, we must change the wavelength of the light to treat each problem.

Now that the boring part is over, next week we will begin to explore the problems we treat and what we use to treat them.
