The safety of light therapy is very high. It can not cause skin cancer.
I have used rubylux product extensively and one of the the pros of using these product is that it doesn’t contain UV rays. UV rays are what makes sunlight rays dangerous for your health when it is in excess. Red light emitting diodes are safe, and do not contain any UV rays.
Carefully follow directives when using any product. Maintain required distance away from skin, minutes of use, frequency and normal safety precautions.
Use red light and near infrared therapy with confidence.
