At-Home Red & Blue Light Therapy Devices Although a 2015 study published in the Indian Dermatology Online Journal suggested that blue light can be helpful in treating mild-to-moderate cases of acne, board-certified dermatologist Dr. Rhonda Klein, MD, MPH, FAAD, explains that not at-home blue light therapy devices are very different from the one inside your dermatologist's office.
She points out that Neutrogena had to recall their at-home light mask due to customer complaints of vision changes. This makes it important to choose a safe at-home device that won't cause any damage to your eyes.
"A safer alternative is the hand-held LightStim device, which covers a small area of skin at a time and reduces the risk of eye injury," says Klein. "However, your best bet for safety and effectiveness is in-office strength LightStim therapy treatment, which is overseen by a board-certified dermatologist."
