Facial massage rollers are a beauty favorite, but what does science reveal? Japanese researchers found they enhance skin blood flow for over ten minutes post-massage and may improve long-term vasodilation—the widening of blood vessels. With few prior studies on facial massagers, the team ran short- and long-term experiments with healthy male and female volunteers to assess effects on facial skin and circulation.
In the short-term test, a five-minute massage boosted blood flow to the massaged cheek by up to 25%. They visualized this using laser speckle flowgraphy, a non-invasive technique.
Strikingly, the effect endured longer than expected. “The increase in skin blood flow after applying the massage roller lasted much longer than we expected,” the researchers noted. “Short-term mechanical stimulation by a facial massage roller increased skin blood flow for more than ten minutes, exclusively in the massaged cheek.”
In the long-term experiment, daily massages on the right cheek spanned five weeks. They tested blood vessel reactivity to a 40°C heat probe for changes in vasodilator response.
Findings indicated improved blood flow response to heat, likely from endothelial cells producing more nitric oxide—a potent vasodilator—in the massaged area.
