Low-intensity indocyanine-green laser phototherapy of acne vulgaris

Near infrared (NIR) diode laser low-intensity (soft) phototherapy with the topical application of indocyanine green (ICG) has been suggested for treatment of acne vulgaris. Twelve volunteers with acne lesions on their faces and/or backs were enrolled in the experiment. Skin areas of the subjects that were 4x5 cm² were stained with ICG solution for 5 min before laser irradiation (803 nm) at a power density up to 50 mW/cm² for 5 to 10 min. For 75% of the subjects, a single treatment was provided and for the other 25%, eight sequential treatments over a period of a month were carried out.

Light therapy in the treatment of acne vulgaris

Dermatology and Lasers Clinic, Tel Aviv Msq, Caesarea, Israel.
Over the past decade, lasers and light-based systems have become a common modality to treat a wide variety of skin-related conditions, including acne vulgaris. In spite of the various oral and topical treatments available for the treatment of acne, many patients fail to respond adequately or may develop side effects. Therefore, there is a growing demand by patients for a fast, safe, and side-effect-free novel therapy.

Lasers promise light relief from teenage misery of acne

ACNE, long the curse of teenagers, could be cured by a treatment first developed to iron out wrinkles, according to doctors at a London hospital. Low Level Laser Therapy normally used in private beauty salons has been tested at the Hammersmith Hospital in West London on 30 patients who were suffering mild to moderate acne.Within 12 weeks their acne had halved, while those on a dummy treatment showed no improvement. Those with the most severe symptoms displayed the most striking improvement, mostly within the first month of treatment. This is significantly faster than most conventional antibiotic treatments, which can take as long as eight months to work...

Phototherapy with blue (415 nm) and red (660 nm) light in the treatment of acne vulgaris.

In this study we have evaluated the use of blue light (peak at 415 nm) and a mixed blue and red light (peaks at 415 and 660 nm) in the treatment of acne vulgaris. One hundred and seven patients with mild to moderate acne vulgaris were randomized into four treatment groups: blue light, mixed blue and red light, cool white light and 5% benzoyl peroxide cream. Subjects in the phototherapy groups used portable light sources and irradiation was carried out daily for 15 min. Comparative assessment between the three light sources was made in an observer-blinded fashion, but this could not be achieved for the use of benzoyl peroxide.

Laser Therapy by Jan Tunér 4.1.1 Allergy, acne systica gravis and eczema

Laser therapy will reduce the symptoms of local allergic reactions through its anti-inflammatory and pain relieving effect. This has been demonstrated by Sakihama [652]. The effect of HeNe laser on irritant and allergic contact dermatitis of the mouse ear and on histamine release from rat peritoneal mast cells was studied. Irradiation (12.2 J/cm2) was performed at various intervals before and after the challenge of an irritated contact dermatitis (ICD) or allergic contact dermatitis (ACD). The laser did not influence the ICD but the allergic response was decelerated. The spontaneous histamine release was inhibited by laser irradiation, while substance P and compound 48/80induced histamine release were not inhibited.
