Blue Light Acne
Therapy
Blue light
acnetherapy – the
experiments
Using blue light in acne therapy is still
rather experimental. However several clinic centers are
working on theory and researching the possibility of
using blue light in acne treatment and the necessary
technologies have already reached the pre-market
application stage. However, the amount of data to
gathered before offering the blue light treatment on the
market is still very high.
Blue
light acnetherapy – the
theory
Blue
light acne treatment is based on an assumption that bacteria of
P. Acne are sensitive to blue light. Mechanism of this
sensitivity is based on fact that bacteria that causes acne
inflammation pumps out tiny molecules called porphyrins. When
those molecules are exposed to certain wavelengths of light,
they produce free radicals that kill the bacteria. When
bacteria are gone, the source of inflammation vanishes and acne
eventually clears up. Some blue light acne therapies also
include red light as a suppository, because red light quickens
the healing processes of human skin.
Blue
light acnetreatments – the
examples
There are several different methods of blue
light therapies going through the last phase of
tests.
1.The ClearLight Acne PhotoClearing (APC) System
is based on blue-violet light spectrum that penetrates
the skin and destroys surface and ductal P. Acne
bacteria. ClearLight technology uses high power enhanced
metal halide lamp with wavelength emission about 407-420
nm. Manufacturer reports that after two week-long
treatment about 80% patients with mild to average acne
shoved improvement, while no side effects were observed.
However, this study has not been published in
peer-reviewed medical literature. Due to lack of
independent medical articles on the effectiveness of high
intensity blue-spectrum (407 - 420 nm) light in acne
treatment, the ClearLight System is considered still in
the research phase.
2. Another one system, Omnilux Blue Photo
Dynamic Therapy is similar to the ClearLight. It involves
the application of the blue light. However Omnilux
utilizes Light Emmiting Diodes technology instead of
metal halide lamp to deliver 408 nm blue light to the
targeted acne area. About 1700 focused diodes produces
enough light energy to be effective versus acne. Same as
with ClearLight, Omnilux still lacks enough tests to
enter pre-market phase.
3. Candela Smooth Beam Laser System is little
different from the two systems described above. Smooth
Beam utilizes laser technology to produce monochromatic
blue light and deliver it strict to the target. Unlike
other laser technologies used in acne treatments, Smooth
Beam is based on the same principle like other blue light
acne treatments. The classic laser therapies use infrared
or red light laser pulses and concentrates rather on
fighting with scars than acne itself. Candela Smooth Beam
Light System use blue laser light rather to kill bacteria
than to vaporize the damaged skin. Unfortunately, this
method also lacks serious clinical studies, so it should
be considered as experimental method.
4. The
Levulan Kerastick differs from above methods in that it uses
chemical support. It starts from topical application of
aminolevulinic acid activated using a blue light
source. ALA is
metabolized in the skin cells to form the photosensitizing
molecule protoporphyrin IX. Activated by blue light, the
molecules release oxygen radicals toxic to acne bacteria.
However, this promising method also lacks medical studies to
prove its effectiveness.
Blue
light acne treatments – the
future
As stated above, every method of blue light acne
therapy lacks enough evidences of its effectiveness. Most
medical companies works hard on this problem while still
improving technology involved. The potential advantage of
this type of acne therapy over other laser methods is its
non-invasiveness and resulting short recovery time. Blue
light can be the future of acne treatment, but there is
still a lot of work to do.
