LED light therapy is an increasingly-popular beauty treatment – even the celebs love it! Here’s what it is, and how it works.

You’ve probably seen them (and freaked out!) when scrolling through social media. The creepy, lit-up masks that look like something out of a sci-fi flick. You may have even spotted the odd celebrity posting a selfie while wearing one. This mask is part of a treatment called LED light therapy, and beauty fans and the skincare-obsessed are hooked!

As daunting as it looks, these treatments are painless, popular and progressive. Here’s what you need to know about it.

What is LED light therapy?

Light-emitting diode (LED) therapy is a beauty treatment available at salons, with at-home devices also becoming more and more widely used. In it, non-thermal LED light energy triggers the body’s cell processes to repair and rejuvenate the skin.

Based on the same principle as intense pulsed light (IPL) devices and laser, LED treatments or masks are a less intense, more user-friendly way to transmit high-energy light forms to your skin.

As for what it treats, the list is endless. It is used to address skin concerns ranging from sun damage to fine lines, to acne and even chronic conditions, such as eczema and psoriasis. These benefits aside, one of the primary reasons its such a hit is because of its ability to restore radiance to the skin, making it calm and bright.

LED light therapy painless, and many find it relaxing. And while some people see results after one treatment, often a course of six is recommended to treat any conditions or generally supercharge your skin. While you might experience some redness and inflammation post-treatment, this usually clears up quickly. Your skin is also more photosensitive, so don’t forget the sunscreen!

Word of warning

The popularity of light therapy has led to a rise in at-home devices flooding the market. While some of them are legitimate, others are not. Ones of inferior quality can cause severe damage to your skin. Even high-end versions can be harmful if used incorrectly.

For these reasons, it’s recommended that you visit a skincare professional if you are considering treatment. After all, safety first when it comes to your skin!
