These three formats account for most of what people actually buy, and they are frequently compared on the wrong axis. Reviews line them up on emitter count and price, as if they were competing products. They are not. They are three answers to three different questions, and the useful comparison is about what each one asks of you.
What follows is a straight head-to-head on the axes that decide satisfaction: coverage, posture, portability, household sharing, distance control, eye considerations and price — plus an honest account of what each format is genuinely bad at.
The short answer: mask, panel or belt?
A mask for the face, because it is shaped for it and includes eye shielding. A belt for the torso, because it wraps, stays put and leaves you free to move. A panel or lamp when you want one device for several areas and have somewhere to set it up. They are not substitutes for each other.
Key takeaways
- Masks and belts are worn; panels are positioned. That single difference drives almost everything else.
- Panels are the most versatile and the most abandoned. Versatility only pays if the device is used.
- Belts cover the most area hands-free and are the easiest to attach to existing sofa time.
- Only the mask includes eye protection, and that is not incidental — it is why you should not improvise a face session with a body device.
- Buy the worn format first. Prove the habit before buying the format that demands a stationary session.
The three formats
Mask
A rigid or flexible shell of LEDs shaped to the face, worn on a head strap, usually cordless and operated by remote. Sessions are ten to fifteen minutes with eyes closed behind a shield. It does one area and it does it properly.
Belt
A light panel mounted in a long adjustable strap that wraps the torso and fastens. Hands free, worn while sitting or moving around, sessions of ten to thirty minutes. Larger emitting area than most other worn formats.
Panel or lamp
A rigid array, usually mains-powered, positioned in front of you on a stand. You set the distance and stay in place. Points at any area, which is its advantage and the source of its adherence problem.
Head to head
| Mask | Belt | Panel / lamp | |
|---|---|---|---|
| Area covered | Face (and neck on some) | Torso band; some state legs and shoulders | Whatever you point it at |
| Worn or positioned | Worn | Worn | Positioned |
| Hands free | Yes | Yes | Yes, but you must stay in place |
| Can you move around? | Seated or reclined | Yes | No |
| Distance to skin | Fixed by design | Contact | You set it — and can get it wrong |
| Eye protection included | Yes | Not needed at that position | No — your responsibility |
| Needs dedicated space | No | No | Usually |
| Portability | Moderate | Moderate | Poor |
| Household sharing | Awkward — touches the face | Wipe between users | Easy — no contact |
| Battery to degrade | Yes | Yes | No, if mains-powered |
| Typical session | 10–15 min | 10–30 min | 10–20 min |
| Vyalight price | $119–$149 | $119 | $85 |
| Adherence risk | Low — attaches to skincare | Low — attaches to sitting down | High — needs a deliberate trip |
Coverage per session
A frequently misunderstood comparison. A panel appears to cover the most, and in raw emitting area it usually does — but coverage that reaches skin is what counts, and that depends on distance and on what is in between.
| Format | Emitting area | Distance to skin | Practical coverage |
|---|---|---|---|
| Mask | Small | Very close, fixed | High for the face — the whole point of the shape |
| Belt | Medium to large | Contact | High across a torso band |
| Panel | Large | Whatever you choose | Variable — falls off substantially with distance |
Irradiance drops as distance increases, so a large panel four feet away is not straightforwardly better than a small array in contact. This is also why panels reward distance discipline: set the position, mark it, and do not drift.
Who should buy which
| You | Format | Reasoning |
|---|---|---|
| Have a consistent skincare routine | Mask | The trigger already exists; add one step |
| Spend evenings on a sofa | Belt | Costs no additional time at all |
| Want one device for several areas | Panel or lamp | Versatility, if you will use it |
| Share with a household | Panel or lamp | No contact, no hygiene question |
| Travel often | Neither panel nor a bulky mask | A pad or compact device is the honest answer |
| Have a fixed chair you always use | Panel | The positioning problem disappears if the position is permanent |
| Have never sustained a routine like this | Belt or mask | Worn formats attach to existing habits; panels do not |
What each format is bad at
The section a comparison article usually omits.
Masks
- Do one area only, and cannot be repurposed.
- Fit is unpredictable across face shapes; rigid masks and pillows do not cooperate.
- Sharing is awkward for obvious reasons.
- Sessions require eyes closed, so you cannot read or work.
Belts
- Shaped for the torso; poor on hinge joints, where a shaped wrap is better.
- Bulkier to pack than a pad.
- Straps and hook-and-loop panels are the usual wear point.
- Worn over clothing for convenience, which reduces the light reaching skin.
Panels and lamps
- The highest abandonment rate of any format, because a session requires going somewhere and standing still.
- Distance is user-controlled, so sessions drift over weeks without anyone noticing.
- Need space, permanently.
- Bright array at body or face height, with no included eye protection.
- Not portable in any practical sense.
The formats this comparison leaves out
Three others are worth knowing about, because for some buyers one of them is the right answer and none of the three above is.
| Format | When it beats all three | Where to read more |
|---|---|---|
| Pad | You want one device for several areas and will accept imperfect fit on each. Cheapest way to find out whether the routine survives. | Pad vs belt |
| Joint wrap | Your area is a knee, shoulder or wrist. A belt does not follow a hinge; a wrap is built for the geometry. | Muscle comfort routine guide |
| Cap or comb | Your area is the scalp. Hair blocks light, so a device that sits against the head or parts the hair is the only sensible answer. | Caps: what to look for |
Notice the pattern: each of these exists because a general-purpose format handles a specific geometry badly. That is the strongest argument in the whole category for buying the shaped device once you know the area — and for buying a general one only while you are still finding out.
A week in each format
Specifications compare badly and routines compare well, so here is a realistic week with each.
Mask
Monday, Wednesday, Friday and Saturday, after cleansing, twelve minutes with the eye shield on and a podcast running. Zero decisions after week one: the trigger is cleansing, the device lives on the bathroom shelf, the remote lives with it. Total added time: about fifty minutes across the week, all of it in a routine that already existed.
Belt
Monday, Tuesday, Thursday, Sunday, twenty minutes during whatever is on. The belt lives beside the sofa. Fastened once, adjusted never after the first week. Total added time: effectively zero, because the sitting was happening anyway. This is the format with the lowest friction of the three.
Panel
Sunday, twenty minutes, because that was the day someone remembered. Setting up the stand takes two minutes, the distance is roughly what it was last time, and the session competes with everything else in the evening because it requires going somewhere and staying still. Total: one session, and a growing sense that the purchase was a mistake.
That last paragraph is uncharitable and it is also the most common outcome we hear about for panels bought as first devices. The format is not bad; it is demanding, and demanding formats need a habit already in place.
Combinations that make sense
- Mask plus belt. The most common two-device household: face in the bathroom, body on the sofa. Two areas, two triggers, no overlap.
- Belt plus shaped joint wrap. If you have a specific joint as well as the torso.
- Pad plus anything. The pad becomes the travel device.
- Lamp as a second device, never a first. Once you know you will use a routine, a lamp covers what worn devices cannot reach.
What rarely makes sense: two devices for the same area, or buying three formats at once before establishing whether any routine survives eight weeks.
Cost per area covered
| Purchase | Cost | Areas served | Realistic weekly use |
|---|---|---|---|
| Mask | $119 | 1 | 3–5 sessions — attaches to an existing routine |
| Belt | $119 | 1–2 | 3–5 sessions — attaches to sitting down |
| Lamp | $85 | Many, in principle | Highly variable — often far fewer |
| Mask + belt | $238 | 2, properly | Both, if each has its own trigger |
The lamp is the cheapest per area on paper and frequently the most expensive per session in practice. That gap is the entire argument of this article.
Frequently asked questions
Which is best: mask, panel or belt?
They answer different questions. Mask for the face, belt for the torso, panel when you need versatility and have somewhere to set it up. Comparing them on emitter count is comparing the wrong thing.
Can a panel replace both a mask and a belt?
In principle it can be pointed at both areas. In practice it lacks eye protection for face sessions, requires a stationary session, and is the format people abandon most. Two worn devices usually get used more than one versatile one.
Is a belt or a panel better for the back?
A belt, for most people — it makes contact, stays put, and you can move around. A panel needs you to sit or stand still at a set distance with your back to it, which is a harder routine to sustain.
Do panels give a stronger dose?
Higher raw output, usually. Whether that translates to a higher dose at your skin depends entirely on distance, and irradiance falls off substantially as you move away. Power without distance is not a dose.
Which format should I buy first?
A worn one — mask or belt — matched to the area you care about. They attach to existing habits, which is what makes routines survive.
Can I use a belt on my face?
No. Belts have no eye shielding and are not shaped for the face. This is one of the few genuinely firm recommendations in this article.
Which format lasts longest?
A mains lamp with a standard replaceable bulb, because the consumable can be swapped and there is no battery to degrade. Worn devices have bonded arrays and batteries, so their service life is bounded by whichever fails first — usually the battery, the strap or a hinge, rarely the LEDs.
What if I want all three?
Buy them one at a time, three months apart, in order of the area you care most about. Buying three at once means owning three devices and building zero routines.
Is a belt or a mask better value?
They are close on price and identical on warranty, so value comes down to which area you care about and which trigger you already have. A mask attaches to a cleansing routine; a belt attaches to sitting down. Whichever of those two things you do more reliably is where the value is.
