The researchers found lemon-derived enzyme-treated hesperidin could reduce swelling in the face and leg, with the study, which is published, claiming to the first in Japan to study this ingredient and its effect.
They first presented the verification study findings at the Health Ingredients exhibition in Tokyo.
The study recruited 88 healthy Japanese men and women who were experiencing daily facial swelling.
Participants were assigned into the lemon-derived enzyme-treated hesperidin (LEH) treatment group or placebo group.
They were told to consume either a LEH (400mg/day of lemon-derived polyphenol powder which contains 300mg of mono-glucosyl hesperidin) or placebo test food for two weeks.
A visual analog scale was used to determine facial swelling symptoms as such skin texture and volume. Calf volume, circumference, and blood pressure were also measured.
The researchers said LEH ingestion contributed to the alleviation of swelling of the face and eyes in the morning.
In addition, LEH was also found to reduce calf swelling.
The company conducted a survey on 1094 participants in September 2019, revealing that more than 70% of women in Japan experience some form of swelling.
The firm hopes this initial clinical trial findings can contribute towards improving women’s quality of life.
