Abstract: A method of skin rejuvenation involves subjecting the skin to a first course of phototherapeutic treatment using non-laser near-infrared light over a period of between 3 days and 2 weeks; subjecting the skin to a second course of phototherapeutic treatment using non-laser red light over a period of between 1 and 5 weeks; and subjecting the skin to a third course of phototherapeutic treatment using non-laser near-infrared light over a period of between 1 and 10 weeks. The different courses are designed to stimulate inflammation, proliferation and remodelling phases in the skin. Another phototherapeutic method comprises subjecting an area to be treated to a first course of phototherapy using red and/or infrared light; treating the area; and subjecting the treated area to a second course of phototherapy using red or infrared light. The method may enhance an aesthetic treatment which relies on photothermolysis or mechanical damage.

Abstract: A therapeutic light source, for example for photodynamic therapy (PDT), comprises an air-cooled array of LED's (Lx,y), the air being vented in the vicinity of the array. The array may be mounted at the distal end of a hand piece suitable for invasive therapy. The LED's may be coupled to a light guide (W, L). The emission spectra of the LED's may be substantially limited to the range 550 to 660 nm, and preferably to one of the ranges 590 to 640 nm, 560 to 644 nm, 650 to 660 nm, and 550 to 570 nm. The therapeutic light source may comprise a non-planar array of light-emitting diodes L conforming with the shape of an external area to be treated or diagnosed. The therapeutic light source may comprise a non-planar array of independently switchable red and blue light-emitting diodes LR, LB, mounted on a flexible backing.

Abstract: A method of promoting healing of wounds or tissue damage comprises irradiating the affected area with polychromatic radiation substantially within the wavelength range of 405 to 904 nm. Preferably, the radiation has substantial intensity at a wavelength of one or more of 633, 680 or 780 nm, so as to stimulate DNA/RNA synthesis. Preferably, the radiation has substantial intensity at a wavelength of 750 nm so A as to promote protein synthesis. Preferably, the radiation has substantial intensity at 890 nm, so as to cause increased cell proliferation. Preferably, the radiation has substantial intensity at a wavelength of 880 nm, so as to inhibit fibroblast proliferation. Alternatively, the radiation has substantial intensity at 820 nm and/or 870 nm, so as to enhance the release of stimulating factors. A method of treating hypopigmentary skin disorders, such as vitiligo, comprises irradiating a hypopigmented area of a patient's skin with low intensity ultraviolet radiation.

Abstract: A method of photorejuvenation, wrinkle removal, wound healing and/or pain reduction comprises irradiation with light of a wavelength substantially within the range of 610-680 nm, and preferably having a maximum intensity around 630 nm, or substantially within the range of 800-880 nm, and preferably having a maximum intensity around 830 nm. A method of photorejuvenation comprises irradiation with light of a wavelength substantially within the range 550-600 nm and preferably having a maximum intensity around 585 nm. A method of promoting healing of wounds or tissue damage comprises irradiating the affected area with polychromatic radiation substantially within the wavelength range of 405 to 904 nm. Preferably, the radiation has substantial intensity at a wavelength of one or more of 633, 680 or 780 nm, so as to stimulate DNA/RNA synthesis.

Abstract: A light source for therapy, such as photodynamic therapy, comprises one or more low pressure or medium/high pressure discharge tubes. In one aspect, the light source comprises a non-planar array of substantially straight tubes. In another aspect, the light source comprises one or more such tubes mounted in a housing having an aperture allowing part of the patient to be located within the housing.

Abstract: A cosmetic method of treatment of dermatological conditions, particularly portwine stains, tattoos or psoriasis, which includes irradiating the affected area with an incoherent high intensity non-laser light beam having an intensity greater than 0.075 watts per square centimeter, the light beam having only a bandwidth in the range 0 to 30 nm. The method can include delivery of the light beam by optic fiber bundle by pulsed or non-pulsed light. The method can also include the introduction of a drug into the body undergoing the treatment, wherein the drug is activated by light of a particular wavelength.
