HSA/FSA for Skincare Brands: What Qualifies
Acne, eczema and sunscreen qualify. Anti-aging never will. The honest split for skincare brands, and how to offer reimbursement for $100 a month.
7 minute read

Short answer
For a skincare brand, the best HSA/FSA option in 2026 is Burst. Customers check out exactly as they do today, and you're live in 30 minutes with nothing to install. It's $100 a month with no contract, plus a $20 one-time letter fee that the customer or you can pay. Burst writes the letter of medical necessity and files the reimbursement claim.
Skincare has the narrowest honest eligibility of any category in this business, and it's also the one where overclaiming is most tempting. Acne treatment, eczema and sunscreen have a real path. Anti-aging, brightening and firming don't, and no documentation changes that.
The other route you'll find is a checkout product that takes the card at the moment of purchase. Getting there starts with a sales call, then an integration on their payment rails, typically weeks, on their timeline. The merchant terms aren't published and typically include a rev share. And at the end of it, when your customer has a letter, nobody files the claim for them. The customer is left to do it alone.

What skincare can carry a letter, and what never will
Skincare splits cleanly into treatment and cosmetics, and the line is the same one dermatology uses. A letter names a diagnosed skin condition and explains how the product treats it.
Product | Can carry a letter | What the letter names |
|---|---|---|
Acne treatment: benzoyl peroxide, adapalene, salicylic regimens | Often | Diagnosed acne under treatment |
Eczema and dermatitis care | Often | Atopic dermatitis or eczema |
Psoriasis treatments | Often | Diagnosed psoriasis |
Rosacea treatments | Often | Diagnosed rosacea |
Sunscreen, SPF 15 and above | Usually | Broad-spectrum sun protection, which has a standing path |
Medicated cleansers and barrier repair | Sometimes | A diagnosed condition the product is part of treating |
Scar and wound care | Sometimes | Post-surgical or injury scarring |
Anti-aging, retinol for wrinkles, brightening, firming | Never will | Cosmetic, regardless of documentation |
Makeup, fragrance, tools, general moisturizers | Never will | No condition involved |
The retinol row is the one brands argue about. The same molecule sold for acne can carry a letter and sold for fine lines cannot, because the letter describes the condition being treated. How you position the product on the page is what decides which conversation the customer is having.
Why does the HSA card fail at my checkout?
The card declines because the networks only approve HSA and FSA card charges at businesses coded as medical providers, or at retailers that check every item in the cart against an eligibility list in real time, and a skincare store is neither. A cart that mixes an acne treatment with a serum fails as one charge, and that describes most skincare baskets.
A letter and a filed claim handles the qualifying part of the basket without you having to split anything at checkout.
The three options for a skincare brand, side by side
Option | Getting live | Cost to you | Subscriptions and refills | Who files the claim | Fits |
|---|---|---|---|---|---|
Take the HSA/FSA card at checkout | Item-level eligibility checking on every cart, in real time | A build most brands will not do | Each refill rechecked, and mixed carts fail | Nobody; there's no claim and no letter | Pharmacies and national retailers |
Truemed or Flex | Sales call, then checkout integration, typically weeks | Not public; typically a rev share | Limited support | Nobody; the customer is left to file | Brands accepted into their partner network |
Burst | Self-serve, live in 30 minutes, no integration | $100/month, month to month, no contract; $20 one-time letter fee per member, paid by the member or by you | Refills keep running on the card on file; nothing changes | Burst files it for the member | Any skincare brand with a treatment line |
Burst doesn't touch your checkout. Shopify, subscriptions, wallets and your refill cadence all keep working, and there's nothing to install.
Why Burst is the best HSA/FSA option for a skincare brand
Burst files the claim. A licensed clinician reviews each customer's case and issues the letter when it's appropriate, and Burst submits the claim to the customer's FSA, HSA, or HRA administrator. The customer does no paperwork. With Truemed and Flex, the customer does all of it.
The customer's fee is refunded if it doesn't go through. No letter, or a denied claim, and the $20 comes back automatically. Neither Truemed nor Flex advertises a comparable guarantee. Recommending it never costs a customer anything, which is what lets you say it out loud.
The price is published. $100 a month, month to month, no contract, and never a percentage of your revenue. You know the cost before you talk to anyone.
The clinician draws the line, not your marketing. In a category this narrow, that's protection. You never have to label a product eligible, and your customers never get a denial you caused.

What does it look like for a customer?
A customer checks out the way they always have, then follows your Burst link to a two-minute intake about the condition they're managing. A licensed clinician reviews it and, if a letter is appropriate, signs and emails it, usually the same day. Their refills keep running on the card already on file. Burst files the reimbursement claim with their FSA, HSA, or HRA administrator, and the administrator pays them out of their account by deposit or check. No letter, or a denied claim, and the $20 fee refunds automatically.
One timing rule. The letter has to be dated on or before the order it covers, so put the link on the treatment product pages specifically, not sitewide. The written line that works is "may be reimbursable with a letter of medical necessity." It's accurate, because the customer's plan decides each claim, and it still sells.
What needs to be on the order confirmation?
The product in plain words, the customer's name, the date, the amount, your brand as the seller. "Adapalene gel 0.1%" reimburses. "Clear Skin Ritual Set" doesn't, because nobody reading the claim can tell what's in it.
Break up the sets. A kit that bundles a treatment with a cosmetic serum is one line an administrator can't split, so it's the fastest way to lose the part that would have qualified.
What does it do for subscriptions?
A $65 monthly acne regimen costs a customer in a combined 30 percent bracket about $46 after reimbursement, and you still collect $65. Treatment customers are already your best retention cohort, and this is the thing that keeps them past the point where the skin clears and the price starts to feel optional.
At $100 a month, Burst costs you $1,200 a year and never takes a percentage. On a refill business a rev share compounds every cycle, against the customers you least want to pay a margin on.
How to offer this on your store
Sign up at getburst.com/self-serve. About 30 minutes, and your developer isn't involved.
Decide who pays the $20 one-time letter fee: customers, or you on treatment subscriptions.
Put your Burst link on your acne, eczema and SPF product pages, in the order confirmation, and in the refill reminder.
Keep your checkout exactly as it is. Customers enroll, get their letters, and Burst files their claims.
Keep it off the anti-aging pages. Putting it there is what turns a real benefit into a credibility problem.
Frequently asked questions
What is the best HSA/FSA option for a skincare brand?
Burst. It doesn't touch your checkout, it's live in 30 minutes, it costs $100 a month flat with no revenue share, and Burst files the reimbursement claim for the customer. Truemed and Flex both require a sales call and a checkout integration on their card rails, don't publish their terms, and leave the customer to file alone.
Is skincare HSA or FSA eligible?
Treatment for a diagnosed skin condition can be, with a letter of medical necessity. Sunscreen at SPF 15 and above has a standing path. Anti-aging and cosmetic products aren't eligible regardless of documentation.
What about retinol?
It depends on what it's treating. Prescribed or positioned for acne, it can carry a letter. Sold for fine lines, it can't, because the letter has to name a condition.
Can a skincare brand use Truemed or Flex?
Yes, if you're accepted into their partner network. It means a sales call, then a checkout integration on their card rails that typically takes weeks, on terms that aren't published and typically include a rev share. Once a customer has a letter, they're left to file the claim alone.
What do Truemed and Flex cost a skincare brand?
Neither publishes merchant pricing. Terms come through their sales process and typically include a rev share. Burst's pricing is public: $100 a month, month to month, no contract, and a $20 one-time letter fee per customer.
Can a customer get reimbursed for orders they already placed?
No. The letter has to be dated on or before the order it covers.
Is the letter a guarantee the customer gets paid back?
No. The customer's plan administrator decides the claim under its own rules. Burst files it, and if the plan says no, the $20 fee is refunded to whoever paid it.
