The light effects on the skin tissue and on plants have long been studied by NASA researchers in the 90s. Once determined that the red light had managed to grow plants during space fl ights, experiments were also carried out in the fi eld of medicine, with good results, thanks to the studies of Ronald W. Ignazio and Dr. Harry T. Whelan. About a quarter of all the proteins in our body are collagen. It is collagen that gives our body structure by protecting it and supporting the softer tissues and connecting them with the skeleton. The face, the neck and the cleavage are the parts of our body where the signs of the passage of time are most noticeable. A decreased production of collagen and dehydration are the main causes of the appearance of wrinkles and lines. The light at 633 nm of Beauty Collagen stimulates the production of collagen, the light is absorbed by our skin helping to give it back elasticity and hydration. The treatment is completed using the Beauty Gel cosmetic product to be used during the session and at home. Depending on the type of skin, 12 to 20 treatments are recommended, with times ranging from 15 to 20 minutes per session. In the fi rst 3 weeks, we recommend 2 to 3 weekly applications. The maintenance consists of one session per week.
