The LED mask market is booming - but how do you separate the marketing noise from truly skin-transforming technology?
According to Sue D’Arcy, CEO of iSMART (the parent company behind faceLITE and a leading global manufacturer of LED phototherapeutic devices), it all comes down to three vital factors: Wavelength, Intensity, and Dose.
Get just one of these wrong, and your LED mask might not work, or worse, could even be unsafe.
Wavelength
Different wavelengths penetrate the skin to different depths, targeting specific cells and chromophores (the parts of molecules that absorb light). If the wavelength is incorrect, the light won't reach the right target, making the treatment far less effective.
Clinically proven wavelengths - like 1070nm - are essential. In fact, 1070nm is the only deeper-penetrating wavelength currently FDA-cleared for tissue healing, with well-documented effects on skin regeneration.*
Intensity
Intensity refers to how much power is delivered by the LEDs. If it’s too strong, it can actually inhibit the desired response or even damage skin. If it’s too weak, there’s not enough stimulation to create visible change. The key is striking a safe, effective balance.
Dose
Dose is a combination of Intensity x Time, so how long you're exposing your skin to a specific power level. Too short, and the treatment is ineffective. Too long, and it could cause damage. The most effective LED treatments carefully calibrate all three factors.
Sue D’Arcy explains:
“Consumers are often misled by brands claiming that ‘more power equals better results’. That’s simply not true. Without the correct balance of wavelength, intensity and dose, an LED mask becomes an expensive gimmick.”
Whether you're exploring LED masks, skincare tech or the science behind beauty devices, Sue D’Arcy is available for expert commentary, interviews, and myth-busting insights.
