Abstract
A process and apparatus for the cosmetic treatment of acne vulgaris utilize irradiation of the affected skin areas with light characterized by a combination of two emission spectra, one in a blue region and the other in a red region.
Claims26
A method for the cosmetic treatment of acne vulgaris, the method comprising:
- providing at least one single-ended fluorescent lamp having two legs, one leg emitting light in a blue region having an average wavelength from 400 to 450 nm and the other leg emitting light in a red region having an average wavelength from 580 to 659 nm;
- and
- simultaneously irradiating affected skin areas with both legs of the at least one lamp.
An apparatus for the cosmetic treatment of acne vulgaris, the apparatus comprising:
- a housing;
- and
- at least one single-ended fluorescent lamp disposed within the housing, the at least one lamp having two legs for simultaneously irradiating affected skin areas with light characterized by a combination of two emission spectra, wherein one leg emits light in a blue region having an average wavelength from 400 to 450 nm and the other leg emits light in a red region having an average wavelength from 580 to 659 nm.
A method for the cosmetic treatment of acne vulgaris, the method comprising:
- providing at least four double-ended fluorescent lamps, the lamps providing light characterized by a combination of two emission spectra, one in a blue region having an average wavelength from 400 to 450 nm and the other in a red region having an average wavelength from 580 to 659 nm;
- and
- irradiating affected skin areas using the lamps.
An apparatus for the cosmetic treatment of acne vulgaris, the apparatus comprising:
- a housing;
- and
- at least four double-ended fluorescent lamps disposed within the housing, the lamps for irradiating affected skin areas with light characterized by a combination of two emission spectra, one in a blue region having an average wavelength from 400 to 450 nm and the other in a red region having an average wavelength from 580 to 659 nm.
An apparatus for the cosmetic treatment of acne vulgaris, the apparatus comprising:
- a housing;
- and
- at least two single-ended fluorescent lamps disposed within the housing, each lamp having two legs, the at least two lamps for irradiating affected skin areas with light characterized by a combination of two emission spectra, one leg of each lamp emitting light in a blue region having an average wavelength from 400 to 450 nm and the other leg of each lamp emitting light in a red region having an average wavelength from 580 to 659 nm wherein the lamps are operated on a dimmable ballast to allow for adjustment of a light intensity of the lamps.
An apparatus for the cosmetic treatment of acne vulgaris, the apparatus comprising:
- a housing;
- at least two lamps disposed within the housing, the at least two lamps for irradiating affected skin areas with light characterized by a combination of two emission spectra, one in a blue region having an average wavelength from 400 to 450 nm and the other in a red region having an average wavelength from 580 to 659 nm;
- and
- a timer in communication with the lamps for limiting the operating time of the lamps.
