Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) let you set aside pre-tax dollars for eligible healthcare expenses. Smuuv Body has partnered with Flex so you can use your HSA/FSA dollars on approved devices like Lulu Pro and Revi Pro+. If you’re unsure whether you have one of these accounts, check with your employer or insurance provider.

Add Lulu Pro or Revi Pro+ to your cart as normal. At checkout, choose “Flex | Pay with HSA/FSA” as your payment option, enter your HSA/FSA debit card details, and click "Pay Now" to complete your order.

Tip: If you don’t see the option, you may be in Shop Pay. Select “Checkout as Guest” to view Flex as a payment method.

1. Add your Smuuv Body device (Lulu Pro or Revi Pro+) to your cart.
2. At checkout, select “Flex | Pay with HSA/FSA” under payment options.
3. Complete the quick Flex form and enter your HSA/FSA card details.
4. If required by your plan, Flex will provide a Letter of Medical Necessity, valid for 12 months, straight to your inbox.

Yes — both Lulu Pro LED Mask and Revi Pro+ are eligible through Flex. Plan rules can vary, so it’s always a good idea to confirm eligibility with your provider.

A Letter of Medical Necessity (LOMN) is written by a healthcare provider and explains why a treatment or device is needed. For HSA/FSA use, some plans require this letter for expenses not clearly listed under IRS guidelines.

With Flex, if your plan requires an LOMN, you’ll automatically receive one by email within 24 hours of purchase — valid for 12 months.

No problem. At checkout, still select “Flex | Pay with HSA/FSA.” You can use a standard credit card, and Flex will send you an itemized receipt to submit for reimbursement (as long as the product is eligible).

This means the product you’re trying to buy isn’t eligible. Only Lulu Pro and Revi Pro+ qualify for HSA/FSA purchases through Flex.

The most common reasons are:

• Insufficient funds in your HSA/FSA account
  
• Incorrect card details (number, expiration, ZIP code, etc.)
  

Flex will alert you during checkout if any details are missing or incorrect so you can update them. If funds are the issue, contact your HSA/FSA provider to confirm your balance before trying again.

First, check your spam/junk folder — sometimes messages from notifications@withflex.com get filtered. If you still can’t find it, email support@withflex.com with the same email address you used to place your order.

There’s no set spending cap on eligible devices like Lulu Pro and Revi Pro+. Your only limit is the available balance in your HSA or FSA account.

Always keep your receipts. Flex provides an itemized receipt with product details, purchase date, and amount paid. Your HSA/FSA administrator may request this for verification.

If you return an eligible Smuuv Body device purchased with HSA/FSA funds, your refund will go back to the original HSA/FSA card you used at checkout. Processing times may vary depending on your plan provider.

No. HSA/FSA rules require refunds to go back to the same account used for the original purchase. Store credit or gift cards can’t be issued for these transactions.

Yes. Hold on to your Flex receipt and any refund confirmation. Your HSA/FSA administrator may require proof of both the purchase and the refund for their records.
