article imageFermented milk improves the skin of young women

Tsukuba - Bizarre as it may seem, one team of scientists have declared that fermented milk, produced using a probiotic, can benefit the skin of young women.
Previous research has shown that probiotic bacteria in milk can help to address certain skin diseases, such as atopic dermatitis. Probiotics are cultured of specific live microorganisms that can theoretically confer a health benefit. The types of microorganisms are lactic acid bacteria.
A new study has turned the focus to healthy humans to see if probiotic bacteria benefit the skin. For the research, the effects of fermented milk produced using a bacterium called Lactococcus lactis (strain H61) was conducted using what became known as H61-fermented milk. The subjects were all young women.
With the trial, twenty-three healthy young women aged between the ages 19- 21 were given H61-fermented milk or conventional yogurt (without probiotics) for one month. Samples of blood were taken before and at the end of the four-week period. In addition, skin hydration (inner forearms and cheek) and melanin content, elasticity, and sebum content (cheek only) were assessed.
At the end of the study the results were evaluated. It was found that skin hydration was higher in both sets of subjects. With the H61-fermented milk group, sebum content in the cheek rose was much higher. This was not found with the conventional yogurt group. For both groups, blood count and serum biochemical measurements were similar and these were within normal ranges.
As skin disorders like psoriasis are worse in colder months, a high sebum content can help. Therefore the results suggest the skin of the women who consumed the probiotic yoghurt was healthier and would be of benefit during colder months. The finding also forms part of a wider review into whether probiotic bacteria can be used to treat skin diseases.
The study was performed at the National Agriculture and Food Research Organization (NARO) Institute of Livestock and Grassland Science (NILGS), Tsukuba, Japan. The research has been published in the Journal of Dairy Science. The paper is titled “Effects of ingesting milk fermented by Lactococcus lactis H61 on skin health in young women: A randomized double-blind study”.
