Do at-home LED face masks actually work to make your skin healthy, more radiant?

PHILADELPHIA (WPVI) -- Some of Hollywood's glowiest faces seem to be treating their skin with LED face masks, and from the comfort of their own home.

The Stormtrooper-like masks promise to give your skin a glow that is out of this galaxy, but can LED face masks really be the force behind healthier and more radiant skin?

Consumer Reports sheds light on everything you need to know.

LED therapy works by interacting with the skin at different levels, stimulating the metabolism, the production of collagen and elastic fibers, and in the case of blue light, as an antibacterial.

Now, you can get those benefits from the comfort of your home, but at-home LED face masks aren't cheap. They can cost anywhere from a couple of hundred to a couple of thousand dollars. So are they worth your money?

At-home masks are typically less effective than in-office visits because they are not as highly powered. But because of their convenience and privacy, they often make a pretty attractive option.

As for the exact benefits, it depends on the type of light. Red light is typically used for anti-aging, and blue light is used to treat acne.

While LED light therapy is safe in the short term, there's less research about its long-term safety.

Always take proper precautions, including wearing eye protection and following directions. Follow the manufacturer's instructions and use the mask only for the recommended time.

LED masks are overall pretty safe, and many are cleared by the Food and Drug Administration. But there are some people who are not good candidates. For example, people who have photosensitivity, have a disease such as lupus, or are taking certain medications.

Results might take time and be subtle, so just keep in mind that patience and consistency are key.

CR recommends to always use the mask as recommended, and if you have specific skincare concerns, it is always a good idea to talk to your dermatologist.
