Abstract: Systems, devices, and related methods for phototherapeutic treatment of skin, and more particularly phototherapeutic treatments for skin conditioning and/or the treatment of skin wrinkles are disclosed. Certain aspects relate to impinging light having a first peak wavelength on skin tissue at a first radiant flux, a second peak wavelength on the skin tissue at a second radiant flux, and, optionally, a third peak wavelength on skin tissue at a third radiant flux. The first wavelength may be selected to produce nitric oxide in the skin and/or to release endogenous stores of nitric oxide; the second wavelength may be selected to promote collagen production. Certain methods involve impinging light having a third peak wavelength that may be selected to reduce inflammation. Devices are disclosed that include combinations of housings, light-transmissive elements, and flexible substrates that are configured to deliver such light to one or more targeted areas.
