When thinking of opting for a red light therapy device, consider determining your objectives related to health as well as your lifestyle compatibilities. A variety of devices are available in the market each created for a specific use, for example, pain relief or skin enhancement. Make sure that the device offers an optimal wavelength between 600-900 nm as it is the ideal range for effective skin penetration. In addition, check if the device has multiple intensity settings, size suited for mobility and self treatment frequency which are tasking requirements for any therapeutic device.
