Q. Does skin poration work?
A. It depends. Hyaluronic acid is rapidly degraded in the skin unless it is crosslinked. Crosslinked hyaluronic acid is used in all currently marketed fillers to increase the longevity of the product in the skin; however, it is not a thin liquid.
Is it possible to put crosslinked hyaluronic acid into the skin with a poration device? I am not sure. Since these devices are sold over-the-counter, no one really wants to know because injection into the skin would technically make the rollers a device that would require Food and Drug Administration attention.
