At-home laser and light-based devices

With the advancement in laser technology, there has been a recent trend in laser and light devices towards 'do it yourself' at-home use. There has been an exponential growth in devices aimed at the treatment of acne, hair removal, and psoriasis. With the exception of the at-home UVB box and excimer lasers, these systems do not require a prescription and patients may purchase the systems as over-the-counter products. Medical treatment still remains the standard of care for most conditions, but these at-home devices play a significant role in the treatment of various conditions. Media and marketing have driven the popularity of these devices and have encouraged patients to try them out. Patients are attracted to at-home devices because of the one-time cost, ease of use, convenience, and privacy of use. Naturally, despite these devices being for at-home use, there should be a level of caution adhered to when using any laser or light device.
