LED phototherapy is considered safe for all ages.  The FDA moved LED phototherapy into its own class ,separate from laser technology, which is  much more heavily regulated, and can pose some risks if not applied by medical professionals.  The Auragen is recommended for almost all ages. From 9 to 99 years old.  Sometimes even younger children can use the Auragen as long as they are mature enough to reliably keep their eyes closed during the session.  Auragen can be safely used with pets. Auragen has devoted pet following including cats, dogs, and even birds. Animals often love and benefit from all wavelengths, but especially Red and NIR. Be sure to turn off Flicker ( Theta /Gamma entrainment) when using with animals.
