|PHOTODYNAMIC THERAPY (PDT)
Photodynamic Therapy - A NEW APPROACH TO LASER TREATMENTS.
is Photodynamic Therapy?
Photodynamic Therapy(PDT) is the newest most
exciting trend in laser light applications for
photo aging, acne and precancerous actinic keratoses.
It involves placing a liquid photosensitizer
on the site to be treated and then irradiating
that area with specialized wavelengths of light
to achieve a desired result. What
this means is we paint the skin with an invisible
colored solution called ALA (alpha
levulonic acid) that soaks into the skin. This
chemical has a special affinity for pre-skin
cancers and oil glands. The skin will
metabolize it into a special invisible color
called a porphyrin. The laser light sees
this porphyrin color as purple and super heats
it. The result is shrinkage of oil glands and
destruction of precancerous cells. What the
patient experiences is a mild tingling during
the treatment. The next few days feel like a
sunburn as the old cells are shed off. Many
patients compare it to a mild to moderate chemical
is most important is that after having the ALA
applied that the patient AVOIDS
DIRECT SUNLIGHT FOR 36 HOURS, this
includes car windows. This is because sunlight
contains the spectrum of light that can unpredictably
activate the chemical and result in a much deeper
peel than was expected.
and pre-skin cancers with Photo Dynamic Therapy
What this means is that we can get the results of
about 2 1/2 IPL treatments with only one
application and get rid of precancerous cells often
before they become apparent. The down time
is a little longer than for a typical IPL treatment
but the results are phenomenal! The pores
become finer, spots flake off and the result is
a subtle air brushed look that your friends and
family will compliment you on.

with severe sun damaged skin manifested
by actinic keratosis, texture, and tone
changes including mottled pigmentation
and skin laxity may see excellent results.
You may also see improvements of large
pores and pitted acne scars. Active acne
can improve dramatically.

achieve maximum improvement of pre-cancerous
(actinic keratoses) sun damage, skin
tone and texture, a series of three
treatments 2-4 weeks apart is the most
effective. Some patients with only actinic
keratoses are happy with just one treatment.
More treatments can be done at periodic
intervals in the future to maintain the
rejuvenated appearance of the skin.
PDT as acne treatment
With PDT you can get the results
from 5 clearlight treatments in one session. Typically
2 treatments 4 weeks apart are sufficient to erradicate
70-90% of the acne lesions for a 6-12 month duration.
For many people this can be the mean having to avoid
oral antibiotics or even accutane.
are several different presentations of acne
ranging from comedonal (blackheads and whiteheads),
popular, pustular, and cystic acne. In many
cases, many of these presentations of acne
can be present on an individual simultaneously.
to photodynamic Acne Treatment, the best available
treatment option for cystic acne was Accutane.
However, with Accutane there are many systemic
side effects including birth defects, liver
abnormalities, mood depression, and virtually
all patients get dryness.
PDT Acne Treatment provides a viable alternative
for all types of acne treatment.
Acne Treatment is done as follows:
which is a clear painless solution, is applied
to your skin and left on for 15-60 minutes.
It is then activated with a specific wavelength
of light called BLU-U or Clear-Light. This
takes about 8-10 minutes. The Levulan targets
active cells like acne sebaceous glands. These
cells preferentially absorb ALA, and are
targeted by the ALA once it is activated;
hence the term, photodynamic therapy. The ALA
will also target sebaceous hyperplasia (which
are those small (1-3mm), benign, bumps on your
skin) and the papules of acne rosacea. Skin
oiliness is decreased, and the appearance of
pores is minimized. The entire skin texture
improves following a Photodynamic Acne Treatment.
The downside of
Photodynamic treatment is that you will
be red and have some skin peeling for several
days after the treatment. Usually, the first
1-2 days are the worst. You must remain indoors
the day following your treatment to avoid sun
exposure, as you are photosensitive for about
24 hours after PDT.
advantages of PDT are rapid treatment of acne
lesions all over the face without scarring
or surgical excision. The skin appears refreshed
and younger following these treatments. We
advise 2-3 treatments at 2 to 3 week intervals
to obtain optimal results. There are no systemic
Intense Pulsed Light and PDT
can be combined with our regular Photorejuvenation
treatments using IPL, which targets redness
and brown spots, as well as stimulates formation
of more collagen in the skin. There is normally
no downtime for IPL treatments without Levulan.
However, one can enhance andboost the IPL photorejuvenation
