Fractional vaporization of tissue with an oscillatory array of high temperature rods: part I: ex vivo study.

Background: Short pulse duration (∼0.1-5 milliseconds) CO2 lasers are perceived as excellent tools for vaporization of craters arrays in fractional skin resurfacing.

Objectives: To present a thermo-mechanical ablation technology, which affects tissue identically to fractional CO2 lasers, however at a fraction of the size and cost of a laser.

Pneumatic skin flattening (PSF): a novel technology for marked pain reduction in hair removal with high energy density lasers and IPLs.

Background: Intense pulsed light (IPL) aesthetic treatment, such as hair removal from large areas, is often very painful. The problems of pain and discomfort can be divided into two different phases: immediate acute pain and the long-term, milder, post-treatment discomfort also associated with erythema. The immediate acute pain is felt during each treatment pulse and can accumulate to an intolerable sensation after a few shots, resulting in the necessity of either using topical analgesic creams which have several limitations or else to considerably slow down the process and/or apply less efficient low-energy densities.

Accelerated reduction of post-skin-resurfacing erythema and discomfort with a combination of non-thermal blue and near infrared light.

The prolonged crusting and erythematic phases following chemical and laser skin resurfacing create discomfort and aggravate patients. Depending on the aggressiveness of the procedure, post-procedure erythema may last from three weeks to several months. iClearXL (CureLight Ltd) is a non-contact, non-thermal blue (405-420 nm)/near infrared (850-900 nm) dual-band light source emitting up to 60 J/cm2 on a 30 cm by 30 cm treatment area.

The utilization of nonthermal blue (405-425 nm) and near infrared (850-890 nm) light in aesthetic dermatology and surgery-a multicenter study.

Background: A major cause of skin aging is a chronic micro-inflammation triggered by UV radiation and external pollutants. It has been demonstrated that blue light diminishes inflammatory conditions and near infrared light enhances circulation.

Objectives: To assess the effectiveness of a non thermal dual wavelength -- blue (405 - 420 nm) and near infrared (850 - 900 nm) -- light source in skin rejuvenation, in the reduction of the duration of post skin resurfacing erythema and in the acceleration of healing of post surgical conditions (face lift and breast augmentation).

Conversion of aesthetic lasers and intense pulsed light sources into inherently eye-safe units.

Background: Laser systems used in aesthetic treatments pose a serious risk to the eyes of bystanders and equipment operators. Although much safer than lasers, intense pulsed light (IPL) sources are also not without risk.

Objective: To present a technology that can convert most lasers and IPL units used in aesthetic clinics into inherently eye-safe devices not requiring the use of protective eyeglasses, thus making them Class I devices.

The effective treatment of acne vulgaris by a high-intensity, narrow band 405-420 nm light source.

Background: Available topical treatments are slow and frequently irritating. Oral therapies may be associated with increased bacterial resistance (antibiotics) or possible severe side effects (oral isotretinoin). In vitro and in vivo exposure of acne bacteria to 405-420 nm ultraviolet (UV) free blue light results in the photo-destruction of these bacteria through the effects on the porphyrins produced naturally by Propionibacterium acnes.
