The three formats use the same technology. The difference is in the geometry – and it matters more than it seems.
Quick Comparison
| Mask | Panel | Spot Device | |
|---|---|---|---|
| Distance | Zero | 15–30 cm | Zero |
| Coverage | Full face | Face, neck, body | Small area |
| Hands-free | Yes | Yes | No |
| Price | Medium | Higher | Low |
Why Distance Matters
Light intensity decreases rapidly with distance. Therefore, a panel with impressive output power might deliver a comparable or lower dose than a mask that rests on the skin.
When comparing devices, the important figure is mW/cm² at skin level, not at the diode output. See how to calculate the dose.
Mask
Who it's for: people who want effortless regularity.
Its strength is even coverage at zero distance and the fact that you can move during the session. Its weakness – it only covers the face.
Panel
Who it's for: people who want to treat the body as well – back, joints, muscles.
Panels are more flexible in terms of area but require you to stand still at a specific distance. If this doesn't become a habit, the device remains unused.
Spot Treatment Device
Who it's for: for localized problems – a single lesion, a small scar.
It's not a solution for the entire face – covering all areas manually takes more time than you will actually dedicate.
Frequently Asked Questions
What about a face and neck mask? A good compromise if the neck part truly fits and doesn't hang at a distance.
Can I use a panel for the scalp? Hair blocks the light. For the scalp, caps with diodes between the hairs are used – see LED Hair Devices.
