Photodynamic Therapy is a treatment performed using the
Blue Light and a topical agent called Levulan, which selectively
kills abnormal cells found in conditions such as acne, skin
cancer, pigmented lesions ("sun spots") and rosacea.
Levulan (ALA) is a naturally-occurring substance found in
the body. When applied directly to the skin, Levulan concentrates
in these abnormal cells. It is then "activated"
by the blue light. In patients with severe to moderate acne,
Photodynamic Therapy kills the acne- causing bacteria (p.
acnes), reduces oil gland activity and in some cases, causes
some peeling of the overlying dead skin. Patients have also
seen a reduction of the pore size, improved skin texture
and reduction of fine lines.
Acne results from the obstruction and inflammation of
the sebaceous glands, and it affects 80% of the population.
Acne typically begins in adolescence with hormonal changes.
However, there are many older individuals who suffer from
adult onset acne.
Q: WHAT IS PHOTODYNAMIC THERAPY?
A: Photodynamic therapy is a process by which a
photosensitizing agent (Levulan) is applied to your skin.
It is then activated with a specific wavelength of light,
which "turns on" the topical solution. Levulan
has been used for the treatment of a variety of different
skin conditions, and it is approved by the FDA for the
treatment of precancerous lesions and sun damaged skin.
Q: HOW IS PHOTODYNAMIC THERAPY WITH LEVULAN DIFFERENT
FROM ACCUTANE?
A: Prior to Photodynamic Therapy, the best available
treatment option for cystic acne was Accutane. However,
Accutane is associated with many systemic side effects
including birth defects, liver abnormalities, mood swings,
depression, and virtually all patients experience eye
dryness and night vision changes. Photodynamic Therapy
provides a safer, viable alternative for all types of
acne treatments.
Q: WHAT SHOULD I EXPECT WITH PHOTODYNAMIC THERAPY?
A: Photodynamic Therapy is a relatively simple
procedure. First, Levulan is applied to the skin and left
on for 30-60 minutes. It is then activated with a specific
light source. The procedure takes approximately 20 to
30 minutes.
Photodynamic Therapy has been used to treat a variety
of skin conditions, including moderate to severe acne,
certain types of precancerous skin lesions, acne rosacea,
and sun damaged skin. Additionally, skin oiliness is decreased
and pores are minimized, leading to a overall improved
skin texture.
