Compositions and methods for treating skin conditions using light and glucosamine hydrochloride
The present invention provides compositions, methods and kits for treating skin, which combine administration of glucosamine hydrochloride and red light having a peak wavelength of about 600 nm to about 750 nm, near infrared light having a peak wavelength of about 750 nm to about 1000 nm, or both.
1. A method of treating skin, comprising topically applying to skin in need of treatment for signs of skin aging a topical composition comprising up to about 2 weight percent of glucosamine hydrochloride, and exposing said skin to both red light having a peak wavelength of about 600 nm to about 750 nm and near infrared light having a peak wavelength of about 750 nm to about 1000 nm, using a light delivery device, wherein the intensity of the light is below about 20 mW/cm 2 .
2. The method of claim 1 , wherein the signs of skin aging are fine lines and wrinkles.
3. The method of claim 1 , wherein the topical composition has a pH of about 3.0 to about 5.5.
4. The method of claim 1 further comprising exposing said skin to ultrasonic energy.
5. The method of claim 4 , wherein the light delivery device delivers light and ultrasonic energy.
6. A method of treating skin, comprising topically applying to skin in need of moisturization a topical composition comprising up to about 2 weight percent of glucosamine hydrochloride, and exposing said skin to both red light having peak wavelength of about 600 nm to about 750 nm and near infrared light having a peak wavelength of about 750 nm to about 1000 nm, using a light delivery device,
wherein the intensity of the light is below about 20 mW/cm 2 .
7. The method of claim 6 , wherein the signs of skin aging are fine lines and wrinkles.
8. The method of claim 6 , wherein the topical composition has a pH of about 3.0 to about 5.5.
9. The method of claim 6 further comprising exposing said skin to ultrasonic energy.
10. The method of claim 9 , wherein the light delivery device delivers light and ultrasonic energy.
