How It Works

Build Your Cart

Look for the 'HSA | FSA Eligible' badge on product pages. Eligible categories include sunscreens, skin care and beauty and wellness tools and devices.

Select Flex At Checkout

Pay with HSA/FSA. If you don't have your HSA/FSA card handy, you can also check out with a regular credit or debit card and submit your receipt to your HSA/FSA administrator for reimbursement.

Confirm Eligibility

You may need to fill out a quick telehealth questionnaire to confirm eligibility for some products. Simply complete the prompts and proceed to payment.

Enter HSA/FSA Card Details

Then, complete checkout. Flex will email an itemized receipt and, if applicable, a Letter of Medical Necessity. Keep these documents in case your HSA/FSA provider requests them.

Make Sure Your Covered

Some products are auto-eligible, but others may require a Letter of Medical Necessity to check out using HSA/FSA. Don't worry — if needed, you'll answer a quick questionnaire, and Flex will email the letter straight to your inbox. It's good for a full year of eligible shopping.

FAQs

Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA) are tax-advantaged savings accounts that help you to pay for healthcare expenses.

Dermsilk has partnered with Flex to allow you to use your Health Savings Account (HSA) or Flexible Spending Account (FSA). This means you can now use your HSA or FSA debit card to buy certain brands more with pre-tax dollars, resulting in net savings of 30-40%, depending on your tax bracket.

Since these funds are pre-tax, you will save up to 30-40%!

No, but some products require documentation from a licensed healthcare provider stating that the item is necessary to treat or manage a specific medical condition. This documentation is called a Letter of Medical Necessity (LOMN). If a product requires a LOMN, Flex facilitates a chat-based consultation that generates the letter in real time.

A letter is essentially a note from a doctor stating that you are purchasing an item to treat or manage a medical condition. More details can be found below.

While Flex offers a telehealth consultation within the checkout process for a frictionless experience, you may request a LOMN from your health care provider instead and submit your purchase for reimbursement with your FSA/ HSA administrator.

HSA/FSA cards are debit cards, and the most common reason for declines is insufficient funds. Please reach out to your HSA/FSA administrator to confirm your balance.

We strongly recommend checking with your HSA/FSA provider to confirm if the items you are purchasing are eligible prior to completing your purchase. However, if you believe your claim has been wrongly denied, please send over any response from your HSA/FSA provider to support@withflex.com and they will provide more information. Please note that employer-sponsored FSAs can determine what products are eligible beyond the IRS's guidelines, so it's important to check prior to purchase.

Yes, you may use the remaining funds on your purchase of eligible items, and a credit or debit card to cover the remainder.

Flex will email you an itemized receipt within two hours of your purchase.

Please forward the request from your FSA to support@withflex.com, who can assist with additional information or a new receipt.

Your return will follow the same process and policies for all items at Dermsilk.

No, this feature is coming soon.

Yes, you will earn Rewards points on any purchase at Dermsilk regardless of payment method.
