We are so confident in the quality of our products that Rejuvenation Science provides an unconditional 100% money back guarantee on all of our nutritional products to our retail customers. Rejuvenation Science guarantees:

  • If you are unhappy with the products for any reason, simply return the product within 30 days of your receipt of the product. We will provide a refund for any number of unopened bottles and 1 opened bottle (even if it is completely empty!) that you purchased from us. Return procedures are listed below.

Return Policy

In trying to keep our business simple for you, we have established the following procedures for customers who have purchased products from us. You don't need a return authorization. You don't need tracking numbers. You don't need permission. You don't need to call us and explain anything.

Just include your name and address on a slip of paper. Please write clearly so we can get your money back to you quickly. We also would appreciate your noting the reason for your return, but it is not necessary.

Mail products to be returned, postage paid, within 30 days of your receipt, with the above information included in the package to:

Rejuvenation Science
5334 Torrance Blvd, 2nd Floor
Torrance, CA 90503

We will promptly issue a refund of the price you paid to us to your credit card upon receipt of your package. We require products to be returned for a refund to be issued. This keeps those few customers who are so inclined from taking advantage of our return policy.
