Med spa financing options fall into two legal categories, not three marketing ones: open-end revolving credit, such as a CareCredit card, and closed-end installment loans, such as a Cherry plan. Which one a treatment page names decides which section of Regulation Z governs the copy around it.
The marketing question underneath is narrower than the vendor comparison pages suggest. A payment plan lifts conversion because the page says a complete, accurate thing about it, and the incomplete version draws complaints. Educational marketing guidance, not legal or financial advice, current as of October 2026.
Two legal categories, not three marketing ones
Regulation Z splits credit advertising by the shape of the credit, not by the vendor. Open-end plans, the revolving kind a card account creates, are advertised under 12 CFR 1026.16. Closed-end plans, a fixed amount repaid over a set term, fall under 12 CFR 1026.24. The triggers differ.
The two are not minor variants. The closed-end rule keys its extra disclosures to four payment figures. The open-end rule, in the Consumer Financial Protection Bureau's published text of 1026.16(b)(1), keys them to the account terms an advertisement mentions, positively or negatively.
What a healthcare credit card actually is
CareCredit's most common promotion is deferred interest, which is not the same product as 0% APR. CareCredit's own explainer says interest builds from the purchase date and lands on the account if the promotional balance is not paid in full by the end of the promotional period, as of October 2026.
The published shape of that offer, on the same page: six, 12, 18 or 24 months on qualifying purchases of $200 or more at enrolled provider locations. CareCredit also notes the minimum monthly payments may not clear the promotional balance in time.
That is a revolving card account issued by a bank rather than a plan the practice extends, which is why the open-end section is the relevant one. CareCredit publishes two other promotion types beside it, a reduced-APR fixed-payment option and a no-interest option, so the page has to name the one a location offers.
What a fixed-term installment plan actually is
An installment plan is closed-end credit: a fixed amount, a set number of payments, a stated annual percentage rate. Cherry's own site gives the range as an APR of 0% to 35.99%, terms between 1 and 60 months, and amounts from $35 to $65,000, as of October 2026.
Cherry states that it does not use deferred interest in its special financing options and that qualified borrowers are eligible for true 0% APR, as of October 2026. The load-bearing word is qualified, and it is the word that goes missing between the vendor's page and the practice's.
Worth noticing what the vendor does with that figure. Cherry prints the full APR, term and amount ranges next to the 0% claim rather than the 0% alone. That is the shape the closed-end rule describes.
The in-house plan goes to counsel first
An in-house plan, where the practice itself lets a patient pay over time, changes who is advertising credit. Regulation Z's advertising section is written around terms a creditor arranges or offers, and whether a practice extending its own terms is covered is a question for a lawyer, not a marketer.
What does not change is the marketing discipline. A number on a page either describes the arrangement a patient will actually be offered or it does not, and the second case is a problem under consumer protection law generally, not only Regulation Z. A prepaid package or a membership billed in advance is different again: nothing is lent.
| Plan shape | Credit type | Advertising section | What a published figure pulls in | Deferred interest |
|---|---|---|---|---|
| A healthcare credit card, such as CareCredit | Open-end revolving | 12 CFR 1026.16 | Disclosures keyed to the account terms named, positively or negatively | Yes, on the deferred-interest promotion |
| A fixed-term loan, such as Cherry | Closed-end installment | 12 CFR 1026.24 | Downpayment, repayment terms over the full term, the APR | Cherry's site says it uses none |
| Pay in four at checkout | Closed-end, four payments | 12 CFR 1026.24 | A number of payments is itself a triggering term | None stated |
| A plan the practice extends | Set by whatever the practice wrote | A legal question, not a marketing one | A stated figure still has to be the real one | Only if the practice wrote it in |
What the triggering terms rule does to a treatment page
On a closed-end plan, four figures pull in extra disclosures. 12 CFR 1026.24 names them as triggering terms: the amount or percentage of any downpayment, the number of payments or period of repayment, the amount of any payment, and the amount of any finance charge.
Set out any one of them and the advertisement owes the downpayment amount or percentage, the terms of repayment over the full term including any balloon payment, and the annual percentage rate using that term, plus the fact that the rate can rise where it can.
This is where a med spa site differs structurally: aesthetics pages are built per treatment, and each wants its own from-$X-a-month line, multiplying the problem by the length of the menu. The rule anticipates the fix. An electronic advertisement giving the detail in a table counts as a single advertisement where the table is clearly set forth and any credit term elsewhere refers to where it begins.
In practice: one financing page carrying the full table, with each treatment page pointing at it by name rather than floating a payment figure in a hero. That pays twice here, because the treatment-level page is the one you least want carrying a third-party script.
Three phrases that cause most of the trouble
Three lines do most of the damage in aesthetics financing copy: 0% financing where the product is deferred interest, as low as $99 a month where the low end is reserved for qualified borrowers, and no credit check where the vendor runs a soft one. Each fails differently.
The first two run into one sentence. 12 CFR 1026.24 opens: "If an advertisement for credit states specific credit terms, it shall state only those terms that actually are or will be arranged or offered by the creditor." Deferred interest is not 0% interest, and a rate available to some applicants is not what the page promises.
The third is a transcription error, and the vendor already wrote the accurate version. Cherry's site describes a soft credit check rather than none, and says eligibility depends on factors including credit score, monthly income and monthly expenses, as of October 2026. No hard credit check is a selling point; no credit check is a claim the vendor did not make.
What this looks like when it runs
HIPAA compliance across digital forms, CRM automations and ad landing pages is the buyer criterion a financing widget sits directly on top of. The working version: a pre-qualification form submits into a system the practice owns, the treatment-level page carrying it gets no retargeting tags, and no treatment detail reaches an ad platform.
Mirastart builds that layer. Booking systems that calculate genuine availability and send confirmations automatically, follow-up automation that chases what people forget, and reporting counted in booked chairs rather than clicks all run in production for Charlotte businesses today. For a financing offer the pieces are narrow: one page carrying the terms table, and a consult booking that arrives with the pre-qualified plan attached.
Those controls are worth checking on any agency, ours included, and we sign a business associate agreement where an engagement genuinely touches protected health information. The practice stays the covered entity.
