Methods of Providing Skin Care Using Phototherapy

A light-emitting device for illuminating the skin of a subject by phototherapy, the device comprising one or more light sources adapted for emitting one or more beams of light having a discontinuous spectrum consisting of a combination of peaks in wavelengths in the range of 510-536 nm, 650-670 nm and 768-792 nm, preferably said peaks having a half-band width between 15 and 35 nm.

A skin care active ingredient for use in the prevention, reduction and/or treatment of a skin-related disorder by phototherapy, wherein said use by phototherapy comprises the steps of:

• illuminating the skin of a subject with one or more beams of light having a discontinuous spectrum consisting of a combination of peaks in wavelengths in the range of 510-536 nm, 650-670 nm and 768-792 nm, preferably said peaks having a half-band width between 15 and 35 nm, wherein said skin is illuminated simultaneously or successively with said wavelengths, and
• applying said skin care active ingredient to the skin;
• wherein said step of illuminating is performed prior to, simultaneous with, or after the step of applying said skin care active ingredient to the skin.

DPHP for use in a method of treating a skin-related disorder, wherein DPHP is topically administered prior to, during and/or after phototherapy, wherein said use by phototherapy comprises the steps of:

• illuminating the skin of a subject one or more beams of light having a discontinuous spectrum consisting of a combination of peaks in wavelengths in the range of 510-536 nm, 650-670 nm and 768-792 nm, preferably said peaks having a half-band width between 15 and 35 nm, wherein said skin is illuminated simultaneously or successively with said wavelengths, and
• applying said DPHP to the skin;
• wherein said step of illuminating is performed prior to, simultaneous with, or after the step of applying said skin care active ingredient to the skin, preferably thereafter.

Skin care active composition for use in a method of treating a skin-related disorder, wherein skin care active composition is topically administered prior to, during and/or after phototherapy, wherein said use by phototherapy comprises the steps of:

• illuminating the skin of a subject with one or more beams of light having a discontinuous spectrum consisting of a combination of peaks in wavelengths in the range of 510-536 nm, 650-670 nm and 768-792 nm, preferably said peaks having a half-band width between 15 and 35 nm, wherein said skin is illuminated simultaneously or successively with said wavelengths, and
• applying said skin care active composition to the skin;
• wherein said step of illuminating is performed prior to, simultaneous with, or after the step of applying said skin care active composition to the skin, preferably thereafter.

A cosmetic method for providing skin care by phototherapy comprising illuminating the skin of a subject with light having a discontinuous spectrum with peaks in wavelengths in the range of 510-536 nm, 650-670 nm and 768-792 nm, preferably said peaks having a half-band width between 15 and 35 nm, wherein said skin is illuminated simultaneously or successively with said wavelengths;

• wherein said subject is a healthy human in need of a cosmetic method for providing skin care by phototherapy, and wherein said cosmetic method provides to said subject skin rejuvenation, moisturization and/or tightening of skin, firming, filling, shaping and lifting skin, improving eye contour, skin radiance boost;
• and/or results in prevention and/or reduction of wrinkles, fine lines, age spots, scars, stretch marks, cellulite, sallow skin, eye puffiness, eye dark circles, hyperpigmented skin, lax skin, skin redness, leathery skin, and baldness.

A method for treating a skin-related disorder by phototherapy comprising illuminating the skin of a subject with light having a discontinuous spectrum consisting of a combination of peaks in wavelengths in the range of 510-536 nm, 650-670 nm and 768-792 nm, preferably said peaks having a half-band width between 15 and 35 nm, wherein said skin is illuminated simultaneously or successively with said wavelengths.
