We stand behind our products completely and work hard to ensure a satisfied experience. Science, clinical testing and user feedback tell us that maximum benefit from MeridaSKIN products comes after at least 6 weeks of consistent use, and that some people have skin that temporarily looks or feels worse before it improves. With those things in mind, we accept returns for a full refund in the original form of payment if the remaining product is postmarked back to us within 90 days from date it was shipped to you. To receive a Return Authorization Number and prepaid shipping label, please email firstname.lastname@example.org. We are always looking to improve and are grateful for any information about the reason(s) for your return.
