Supplements containing coriander seed oil may reduce skin sensitivity and reduce itching, suggest new data from a pilot study from France.

Writing in Food & Nutrition Research​, scientists from Seppic Research and Innovation report that coriander seed oil (CSO) reduced skin redness in response to repeat skin “stripping” (multiple applications and remove of surgical tape from the skin), and less itching in response to a lactic acid application, compared with placebo.

“To the best of our knowledge, this is the first time that CSO has demonstrated a soothing effect in vivo. In the first intention, as it was a pilot study, only women with sensitive skin were recruited to ensure as much as possible a homogeneous group for inclusion. Furthermore, the prevalence of sensitive skin is higher in women than that in men,”​ wrote the researchers.

Sepibliss

The study used Seppic’s branded Sepibliss coriander seed oil, which was launched in 2018 from preliminary work conducted by the company’s innovation group in France, Sebastien Merchet, Sales & Marketing Manager, Nutrition for Seppic Inc, told us.

“It is the nutricosmetic ingredient dedicated to sensitive skin,” ​he said. “Since then [2018], we have conducted additional research, including the just published clinical study.”

The ingredient is described as a 100% virgin coriander seed oil, extracted without solvent and manufactured locally in the South West of France.

Study details

The new pilot trial included 60 women with sensitive skin randomly assigned to receive either sunflower oil (control) or the coriander seed oil (200 mg) for 56 days. Sensitive skin was determined by reactivity induced by mechanical (stripping) or chemical stress (lactic acid).

The data indicated that the coriander seed oil attenuated the redness induced by successive skin stripping on the forearm of volunteers. In addition, CSO regulated the itching sensations induced by applying lactic acid around the nose, and such effects were observed after 28 days of consuming the coriander seed oil supplements.

“From a user perspective, the efficacy of CSO was perceived by the subjects as better than the placebo, especially on the criteria of repair, relief, tolerance, and protection,” ​stated the researchers.

Commenting on the potential bioactives responsible for the observed effects, the researchers noted that CSO contains an omega-12 fatty acid called petroselinic acid, which has been reported to “reach tissues and decrease arachidonic acid concentration, and thus, petroselinic acid could contribute to the anti-inflammatory and soothing effect of CSO.”

CSO also contains linoleic acid, said the researchers, and this may contribute to the structure and barrier function of the epidermis, but linoleic acid is also found in sunflower oil, and no benefits were observed in that group.

“The soothing effects observed with CSO in women with sensitive skin are very promising,”​ concluded the study researchers. “Further studies are now needed to confirm them and to understand the associated mechanisms of action.”

Seppic’s Merchet confirmed that additional studies are indeed planned. “One is ongoing, and we hope to be able to share conclusions within the year,”​ he said.

“We are excited to continue bringing peer reviewed science to the ingestible beauty space on innovative areas such as skin soothing,” ​he added.
