Colour is not a specification
Wavelengths are expressed in nanometres. Two products described as red may have different specifications. The LED count alone cannot tell you the intensity reaching the skin or predict a beauty result.
Ask for the right model’s information
Look for instructions and specifications tied to a model reference. A value on a generic listing or a similar-looking product is not a measurement of your device. Éclavie’s MASK-01 page distinguishes manufacturer declarations from measurements we have not made. We do not publish wavelengths while conflicting information remains unresolved.
Choose for your routine
Choosing a colour is not a diagnosis. If your aim relates to a skin condition, speak to a healthcare professional. Our selection is presented for a home beauty ritual, without a guaranteed result or a promise to treat a condition.
