Although Kinzeno is marketed for everyday external use, consumers should still use reasonable precautions.
The product should be kept away from the eyes and mucous membranes. It should not be applied to broken, irritated, or damaged skin unless a healthcare professional has specifically recommended doing so.
Kinzeno's own instructions advise discontinuing use if irritation occurs and consulting a healthcare professional when appropriate.
