One of the most popular types of light therapy is known as red light therapy. This is because it uses lights that are tinted red in order to provide you with the benefits you are looking for. While sunlight does not appear red, this tinting can help to stimulate the skin more effectively so that your body will produce the desired hormones.
There are many different options available for red light therapy. Some products will come in the form of a face mask that you put on. The mask has a series of red LED bulbs on the inside so that they are directed right at your skin. Other options will work like a lamp and emit red light in all directions so that you can be exposed if you are anywhere in the area. You will typically want to look for lamps that can produce light in the 600-700 nm range, which will be visibly red.
