Sweat contains a natural antibiotic that controls the bacteria living on your skin.
Birgit Schittek and her team at Eberhard-Karls-University at Tubingen in Germany discovered that human sweat has an antibiotic that they called Dermcidin. It controls the nastier bugs – for example, it kills the bacteria E. coli and Staphylococcus aureus, and the yeast Candida albicans
Dermcidin is an unusual protein/antibiotic. Dermcidin, which has 47 amino acids in it, has a broad spectrum of activity against many different bacteria. It’s made only in the sweat glands.
People with repeated skin infections could need antibacterial boosters on their skin. Maybe they could be sold in a cream.The big difference between Dermcidin and the other antibacterial skin chemicals is that it’s produced whenever you sweat – not when you’ve got inflammation.
Now rock singers generally lead fairly unhealthy lifestyles with very odd hours. But they usually have very good skin. They sweat a lot. Maybe Dermcidin is the secret of their solid gold complexion. And maybe people who sweat a lot could get a little extra income by squeezing the Dermcidin from their sweaty t-shirts …
