LED light therapy at home: what each colour is for

LED masks look faintly ridiculous and the marketing around them is often worse. Here's a plain explanation of what the colours are, without the overreach.

The colours

An LED mask emits light at particular wavelengths. Different wavelengths penetrate to different depths, which is why devices offer more than one.

Red — the long wavelength

The longest of the visible wavelengths used in these devices, and the one most people associate with the category. Traditionally used in evening routines, for a rested and luminous look.

Amber — the middle

A softer, warming light. Favoured where skin looks reactive or uneven in tone, and often the most comfortable setting for people new to the devices.

Blue — the short wavelength

Sits at the other end. Commonly chosen by people looking for a fresh, clear-looking complexion.

How to read the claims

This is where the category gets untidy. You'll see LED masks advertised as clinical-grade, as treatments, as cures for named skin conditions.

In Australia, a device marketed with therapeutic claims is a different regulatory animal from one making cosmetic claims — and most of the masks making the boldest claims have done none of the work that would justify them. A brand willing to say "treats" about a $60 import is a brand telling you something about itself.

Our own position: we don't sell a mask today, and any we did would be held to the same line — described by how it looks and feels to use, with no claims we can't stand behind.

Getting the most out of one

  • Consistency beats intensity. Ten unhurried minutes several times a week does more than an hour once a month — here's the cadence that actually works.
  • Clean skin, then serum, then light. Makeup and heavy occlusives sit between the light and your face.
  • Close your eyes. Reputable devices are designed with this in mind, but it's a sensible habit regardless.
  • Give it time. Anyone promising results this week is managing your expectations badly on purpose. An honest timeline here.

Before you buy one

Fit is the most-complained-about thing in LED mask reviews and the least-discussed thing in the marketing. Six things to check before you spend the money — the nose bridge being the one that catches most people out.

Is it worth it?

Honestly: it depends what you want from it. If you're after a considered ten minutes at the end of the day and you like how your skin looks afterwards, it's a pleasant and low-risk addition to a routine.

If you're hoping it will replace sun protection, it won't, and we'd rather tell you that before you buy than after.
