Red light therapy has become a real game changer in the beauty world as it is a form of treatment that works on the skin with no invasion at all. There are a number of parameters to take into account while buying a red light therapy beauty device, such as the wavelength, the area that needs treatment, and the portability of the device. Any device that emits 600-650nm or 800-850nm wavelengths is good for the skin, as such wavelengths penetrate deeply and promote healing and repair of damaged cells. Also, using a device that fits your lifestyle – for example, a hand-held device for localized treatment or a full-body panel for larger session – will improve your overall experience and results.
