They do absolutely nothing
Update following contact from the founder
I initially left a negative review because the sleep patches did not work for me and, after looking into the ingredients and science, I questioned the claims being made about them.
Since then, Ara, the founder, has contacted me personally and refunded me in full. This was not conditional on changing my review. I want to give credit where it is due: her customer service has been excellent, she has engaged openly with my questions and has been refreshingly candid rather than dismissive.
However, that conversation has actually confirmed my main concern about the product.
RESTELLE advertises its patch as containing 5mg melatonin delivered through the skin over approximately eight hours, and I have also seen advertising making specific claims about duration and absorption.
I asked Ara whether RESTELLE has independent permeation or pharmacokinetic testing on the finished patch demonstrating how much melatonin actually crosses the skin and the resulting blood concentrations. She confirmed that it currently does not.
I therefore remain uncomfortable with specific claims about absorption and an eight-hour effect without finished-product evidence demonstrating them.
I have genuine sympathy for a founder building a growing business, and my dealings with Ara have left me with a very positive impression of her personally. But I don’t think excellent customer service can substitute for evidence behind objective health-product claims.
I will give the remaining patches the longer trial Ara suggested and update this review again if my experience of the product changes and have improved my score to reflect the customer service standards.
