Acne is a chronic disease of the pilosebaceous
follicle and is the most common skin disease,
affecting up to 80% of individuals at some time
lives. Acne begins usually
adolescence, when hormonal changes cause the
enlargement and then the obstruction of
sebaceous glands in the skin. The obstruction of
the gland opening causes the accumulation of
followed by abnormal
the bacterial population,
predominantly Propionibacterium acnes (P.
acnes). These pathophysiologic events result in
inflammatory pustules of acne. Not only can
they cause disfigurement and permanent
scarring, they can also have an adverse effect on
profound emotional lack of confidence, which
may lead to social phobias, withdrawal from
society, clinical depression, and suicide. Topical
acne medications are usually irritating to the
skin and more than 40% of acne bacteria are
insensitive to oral antibiotics. Therapy with
Accutane is associated with possible severe side
effects, is costly and involves long treatment.
Treatment time for responsive patients is usually
at least three to four months.
Sun exposure is known to have some beneficial
effects in up to 70% of patients with acne.
Although solar or artificial UV light has a mild
camouflage effect on acne, its comedogenic and
photo-aging effects diminish its use in acne
therapy. It is known that P. acnes produce
porphyrin during their normal life cycle, as part
of their normal metabolic process. Visible light
in the blue range, or to a lesser extent in the red
range, induces a photo destructive effect on P.
acnes that may take part in the decrease in acne
severity during the summer. A decrease in the
number of acne lesions was achieved previously
by exposure to light sources that produce blue
