The skin forms a natural barrier between the external environment and our body. It acts as a mechanical barrier, preventing the penetration of various substances and microbes into the body’s tissues. Sweat, which is secreted on the skin, has an acidic pH and contains substances that destroy microbes and support immunological recovery, as the skin is part of the body’s defense system. A variety of beneficial microbes live on the skin, preventing harmful microbes from settling and thriving. When the skin is compromised, our ability to defend against external influences is also reduced. The most common form of skin disruption is dehydration.
