Firstly, when purchasing an at-home LED mask check the label to see that it is FDA-cleared, says Rabach. Next, wear blackout or opaque goggles at all times when using it. And follow all the instructions from skin prep, to usage to duration. Read the instructions fully before beginning so you know the full deal, then read them throughout the procedure. And consult the fine print. Benjamin suggests speaking with a professional to figure out the best length and frequency of treatment for your skin.
It's also important to temper expectations. Shamban highly recommends LED as a treatment, but says the only "Insta-result" will be the lit photo for Instagram. No device will have the power of an in-office treatment. And even professional treatments require multiple sessions and consistency for results. At-home devices are a lot less powerful. Rabach adds there is no scientific data supporting that at-home LED treatments are effective for improving skin over time.
Furthermore, Shamban always recommends people check with a board certified dermatologist before starting anything new including products, tools and technologies. After all, they're professionals for a reason.
