A post in r/EstheticsBusiness sets out a menu question that most treatment businesses get wrong in the same direction. LED usually sits on the menu as an add-on, priced separately and offered during consultation. The device is a real investment and the session takes room time, so charging for it looks like the obvious answer. The counter-argument is results: LED depends on consistency, and a client who adds it once every few visits never accumulates enough sessions to see what it does.
Both arguments are correct, which is why the menu question cannot be settled by opinion. It can be settled by treating LED as a specific kind of service with its own economics, and those economics are not the same as the ones behind a chemical peel or a mask upgrade.
Why the LED decision is not like any other add-on
Most add-ons on a facial menu sell a one-time outcome. A client buys an exfoliating upgrade, receives the exfoliation that day, and sees the result that week. The value is delivered inside the appointment, so the pricing question is simple: does the price of the upgrade exceed the cost in product, time and labour?
LED does not work that way. Its effect is cumulative, and no single session produces the visible change a client is paying for. What the client is actually buying is the outcome of a course of sessions. That changes everything about where the decision belongs, because a service whose value is only realised in a series cannot be evaluated session by session. Priced as a one-off add-on, it will be bought occasionally, under-observed, and judged on a result it was never designed to produce alone.
There is a second difference, and it runs the other way. Once the device is owned, the marginal cost of a session is close to nil. No consumable is used in meaningful quantity, the labour is largely the practitioner's presence rather than active work, and the room is occupied during a period that would otherwise be mask time. So the cost structure is unusually favourable on the margin, and unusually heavy up front. Any service with that shape needs volume to work, and pricing it as a scarce upgrade does the opposite.
The consistency argument, stated precisely
The case for including LED in every facial is usually made loosely, as a claim that clients need a lot of sessions. The more useful version is about observation rather than intensity.
A client who buys LED occasionally never reaches the point of comparison. They cannot tell you whether their skin is calmer, their redness reduced, or their recovery faster, because they have no consistent baseline. Without that, the practice cannot demonstrate the effect, cannot justify a price, and cannot build a series — and the client quietly concludes that the add-on did nothing. The service then fails on the evidence, not on the treatment.
Included in every facial, the situation inverts. The protocol runs at every visit, the client's skin is observed consistently, and the improvements that show up over six or eight appointments have a comparison point. That comparison is what makes a client a believer, a rebooker, and eventually a buyer of a series or a home device. The initial inclusion is not a discount. It is the sampling period that makes the paid version sellable at all.
The margin argument, stated precisely
The case for charging separately is about protecting the base price and making the clients who want the service carry its cost. That is sound logic for a one-off treatment, and it is undermined by one detail: LED is the cheapest thing on the menu to run and one of the most expensive to leave idle.
A device that sits unused still consumes its purchase price, its service contract and its floor space. The relevant comparison is not "revenue per LED session versus revenue per facial" but "revenue per session with the device versus revenue per session without it, given that the device is already bought". If including LED lets the practice raise the base facial price by a modest amount, or hold the price while adding a genuine differentiator, or reduce discounting because the included service gives the treatment a reason to be priced as it is, the inclusion can outperform the add-on model while looking like a giveaway on the menu.
There is also a cost on the other side of the ledger. An included service is much harder to remove later than a paid one is to add. A client who has had LED in every facial for a year reads its removal as a price rise, and the practice ends up explaining that decision in a room, one client at a time. That is the main reason inclusion should be entered deliberately rather than by accident.
The three-position menu, and how to test it
Rather than settling on one answer, the practical route is to place the service in one of three positions, run it for a defined period, and compare the numbers that matter. The three positions are the familiar ones, but each has a version worth testing.
Pure add-on. Priced separately, offered at every consultation, with a script that explains why it works better as a course than as a one-off. This position tests whether the practice can sell the outcome rather than the session, and it works best where the client base is experienced and buys on explanation.
Included in every facial. Rolled into the base price with an increase that the practice can defend. The number to watch is not the LED revenue, which disappears, but the base price, the rebooking rate and the series conversion. This position tests whether the service can carry a price increase on the strength of a differentiator.
Included in packages and series, add-on for single visits. The compromise position, and often the strongest commercially, because it uses the device to make a package cheaper to sell while keeping a paid route for occasional visitors. It also gives the practice a clean answer when a single-visit client asks why the package costs what it does.
Whichever is tested, the comparison should run long enough to include at least one full rebooking cycle for the treatment in question. A month is not a test. The metrics that decide are rebooking rate, average ticket, the proportion of clients who move to a package or series, and the utilisation rate of the device across the test period.
What "the device has paid for itself" actually means
The phrase appears in most of these discussions and is usually left undefined, which is a problem, because it contains a decision.
A device is paid for when the contribution its sessions generate has covered its acquisition cost. Contribution means the revenue attributable to the service, less the cost of delivering it, less any share of the room and labour that would not otherwise have been incurred. For a service with near-zero marginal cost, contribution per session is high and the payback period is short — but only if the sessions happen. Idle capacity is what stretches payback, not low price.
Two consequences follow. First, the payback calculation should be done in sessions, not months: the practice knows how many LED sessions a month it actually runs, and dividing the device cost by the contribution per session gives a number it can plan against. Second, the fastest way to shorten payback is to increase session volume, which is precisely what inclusion does and what add-on pricing does not. This is the strongest argument for inclusion, and it is an argument about utilisation, not about generosity.
Where the device itself changes the answer
Not every LED unit is priced and operated the same way, and the equipment decision feeds directly into the menu decision.
The relevant properties are how much labour the session requires, how much room time it consumes, whether it can run concurrently with other parts of the treatment, and what it is capable of beyond LED. A unit that runs on its own for twenty minutes while the practitioner performs a massage on the arms, or completes the chart, costs almost nothing in labour and occupies time that was already committed. A unit that requires the practitioner at the controls for the full session is expensive to run and much harder to include profitably.
Multi-function devices change the arithmetic further, because the same room time and the same capital purchase generate more than one billable capability. A combined oxygen and LED dome, for example, gives the practitioner an oxygen-based service and a light-based service from one footprint, so the session time can carry either a specific claim or a broader one, and the menu can be built around a package rather than a single add-on. That flexibility is worth pricing at the outset: it is the difference between a device that supports one line on the menu and a device that supports a protocol.
For practices evaluating that combination, one example of the category is the Oxygen Jet Dome O2toDerm LED light therapy oxygen jet facial machine, which pairs an oxygen dome with LED in a single unit. The practical test when comparing units is not the specification sheet but how the session breaks down in the room — how many minutes the device runs unattended, and what the practitioner can do during them. A device that fills twenty minutes of the treatment with no hands on the client is a different commercial proposition from one that needs constant attention, even at the same price.
Answer the protocol question before the pricing question
Most menu debates about LED are really debates about something that was never settled: what the practice tells clients the service does, and over what period.
If the promise is a visible change in one session, no pricing model will support it, and the practice will end up discounting or apologising. If the promise is a course of sessions producing a gradual improvement in redness, calm, healing or the result of another treatment being performed alongside it, then the pricing model has something to attach to, the series makes sense to the client, and the add-on conversation at consultation has a purpose beyond revenue.
That framing also determines whether the practice can make any clinical claims at all. LED's effects and the appropriate number of sessions depend on the wavelength, the device and the client, and treating those parameters as settled when they are not is how practices end up making promises they cannot support. Writing the protocol down — sessions, intervals, what to expect and when — is the precondition for pricing it, and it is also what makes the service defensible in a consultation.
Switching positions without losing rebooking
If the decision is to move from add-on to included, or the reverse, the transition is where the damage happens. Both directions have a standard failure.
Moving to included without raising the base price converts a revenue line into a cost with no compensating benefit, and the practice concludes that inclusion does not work when the experiment was never priced. Moving away from included without a story reads as a price rise, and the clients most likely to object are the regulars, who are also the ones whose rebooking matters most.
The transition that works is staged. Introduce the change as a protocol upgrade at a defined date, with the base price adjusted at the same time and the reason stated in one sentence — what the service does and how often it needs to run to do it. Move existing series and package holders across at their next renewal rather than mid-course. And keep a paid route available for single visits, so the client who does want to buy LED on its own can still do so. That last point is what makes the change a re-pricing rather than a removal.
The answerable version of the question
Should LED be included in every facial or sold as an add-on. The answer depends on four numbers, and they are all measurable inside the practice: the contribution per LED session once the device is owned; the current utilisation rate of the device; the rebooking rate of clients who receive the service as an add-on versus as part of a protocol; and the base price the practice is able to hold with and without the service included.
Run one position for a full rebooking cycle with those four numbers tracked, and the menu question answers itself. What should not happen is what usually does: leaving the service in the position it inherited, priced the way it has always been priced, while the device is justified on results it was never given the volume to produce.
