LED Skin Sessions, Explained Simply
The glowing masks look futuristic. Here is what they do, what they don’t, and what to check first.
LED skin sessions have become one of the most recognisable images in skincare: a softly glowing mask, a quiet room and a few minutes of stillness. Behind the image is a simple idea, and a field of research that is still developing.
How it works, in one paragraph
A device shines light at specific wavelengths onto the skin. Red and blue light are the colours most often used in skincare settings, and some devices also use near-infrared light, which you cannot see. The provider chooses colours and timings for the session.
What the evidence says
Studies of light-based skincare report a range of results, and they differ in devices, settings and the people taking part. That is why it is worth treating LED as one part of a routine rather than a promise of a particular outcome.
Before your session
- Mention medicines, supplements or skincare that can increase light sensitivity.
- Ask what eye protection is provided.
- Ask how long the light will be on and how often sessions are usually offered.
- If you have a condition affected by light, check with your doctor first.
During and after
Most people find the session calm and painless. Afterwards you can usually carry on with your day; the provider will tell you if any aftercare applies.
