Refund policy

No Returns, Refunds Only 

Because Longevity Protocol is a topical skincare product applied directly to the skin, we do not accept physical returns of opened or used product. Once a unit leaves our facility, we cannot resell it for hygiene and safety reasons. 

We've built in two ways to make it right if something isn't working for you: a 45-Day Satisfaction Guarantee and our Damage & Defect Policy.

45-Day Satisfaction Guarantee

If you've genuinely given Longevity Protocol a fair trial and aren't seeing results, we'll refund your order within 45 days of delivery.

To qualify:

• The request must be submitted within 45 days of the original delivery date (per carrier tracking)
  
• The guarantee applies to your first order only.
• Refunds are issued for the product price only. Original shipping, duties, and taxes are non-refundable.
• Refunds are processed to the original payment method within 10 business days of approval. Bank posting times vary.
• The guarantee covers orders purchased directly from darkfinlabs.com. Orders from third-party retailers must be handled through that retailer.
• Bulk orders, promotional bundles, gifts with purchase, and discounted/sale items are excluded.
• We reserve the right to decline refund requests that show a pattern of abuse across accounts, addresses, or payment methods. 

  
  

  Damaged, Defective, or Incorrect Orders

  If your order arrives damaged, defective, or incorrect, we'll make it right — no qualifying period, no fine print.

  • Inspect your order upon delivery and contact us within 7 days of receipt if there's an issue.
  • Email support@darkfinlabs.com with your order number and clear photos of (1) the damaged/incorrect item and (2) the outer shipping packaging.
  • Once verified, we'll offer your choice of a full replacement or a full refund, including shipping.

  Claims submitted after 7 days, or without supporting photos, may not be eligible. 

Refund Processing

Once a refund is approved, you'll receive a confirmation email. Refunds are issued to your original payment method within 10 business days. Depending on your bank or card issuer, posting can take an additional 3–5 business days.

If more than 15 business days have passed since your approval email and the refund hasn't appeared, contact support@darkfinlabs.com and we'll investigate.
