Claims21
A method for treating pigmented lesions on the skin,
- said method comprising irradiating the skin with electromagnetic radiation having a wavelength that is absorbed more efficiently by the pigmented lesion than by dermal blood vessels or hemoglobin.
A method of treating unwanted vasculature and pigmentation of the skin with the same device using two or more wavelengths of electromagnetic radiation, said method comprising simultaneously or sequentially administering said two or more wavelengths, wherein one wavelength is for said unwanted vasculature and the other is outside of the absorption peaks for hemoglobin,
- said method comprising irradiating the skin with electromagnetic radiation having a wavelength 550-560 nanometers, 601-690 nanometers or combinations of these wavelength ranges.
