Body odour is unpleasant. Sweating, however, offers one great benefit for your skin: Some bacteria such as Nitrosomonas eutropha metabolise, among others, components of sweat and may improve skin health positively. Researchers in the US have confirmed these findings in a placebo-controlled study.
For the study, they asked participants to apply a suspension of live Nitrosomonas bacteria on their face and scalp for one week. Afterwards, the subjects reported qualitative improvements in skin condition. The researchers were also able to show that in almost one of three test persons, presence of the bacteria could be detected even two weeks after application. Also, improvement in skin condition correlated with the verified level of bacteria.
The scientists say that the bacterial species Nitrosomonas eutropha – a natural and ubiquitous inhabitant of soil and water – has the ability of converting ammonia into nitrite. Apparently, this is just what the skin needs. Nitrite and nitric oxide, which are products of ammonia conversion, play an important role in wound healing and inflammations, the US researchers report. In their next step, they intend to assess the therapeutic potential of the bacteria for acne or chronic wounds.
