The Kinzeno gel contains no oral NSAIDs and has no known drug interactions with common medications including blood thinners, blood pressure medication, or heart medication. However, if you are on a complex medication regimen, we always recommend checking with your pharmacist or physician before adding any new topical product to your routine.

No. The magnetic rollerballs in the Kinzeno applicator contain neodymium magnets. If you have a pacemaker, ICD, cochlear implant, insulin pump, or any other implanted electronic medical device, do not use this product. Please consult your cardiologist or device specialist before use.

No on both counts. The Kinzeno gel is formulated to be odor-neutral — there is no strong menthol or medicinal smell. It is also fast-absorbing and non-greasy. You can apply it before bed without worrying about staining your sheets, and before getting dressed without worrying about residue on your clothes.

Most users report noticing a difference within the first few applications. The Mannitol in the formula has been shown in clinical studies to begin working in approximately 16 minutes with a median relief duration of 4 hours. Individual results vary depending on the severity and type of pain. We recommend consistent daily use for at least 2 weeks to assess the full effect.

Then you pay nothing. Kinzeno comes with a full 60-day money-back guarantee. If you are not satisfied for any reason — including if you simply feel it didn't work well enough for your pain — contact our support team within 60 days of your purchase for a full refund. No lengthy explanations required. No hassle. We stand behind this completely.
