Skin microflora is a delicate balance of bacteria and fungi, which feeds from our sweat, Sebum and dead Skin. They do not harm the Skin because they need the Skin in order to survive. In return they protect us from hostile bacteria and fungi that can cause itching, redness, excess scaling, red spots and irritation. Recent studies show that the first barrier of our body is formed by billions of friendly and beneficial microorganisms living on our Skin. These microorganisms are called Skin microflora or Skin microbiota. They adapt to our natural Skin conditions like pH levels, humidity and temperature. Our Skin, and these friendly organisms live together in perfect harmony. Beneficial microorganisms (Saprophytic flora) inhabit the Skin surface, leaving no place for foreign and hostile organisms (Pathogenic flora). When a harmful foreign organism wants to settle down on our Skin it encounters several serious problems:
- The Skin conditions are in favour of the friendly organisms and restricts the ability of harmful ones to grow.
- Beneficial organisms are present in high population. They eat all the food available leaving nothing for the harmful organisms to eat, and therefore restricting their chances of growth.
- More harmful bacteria penetrate into the Skin
- The Skin defence system is alarmed and produces more and more oxidising components to kill the harmful bacteria. Excess oxidation destroys healthy Skin cells, leading to redness, itching and irritation.
- The destruction of healthy Skin cells leads to destruction of the Skin barrier.
- The destruction of the Skin barrier leads to more penetration of foreign substances such as harmful bacteria.
- These changes lead to infection and inflammation
- Use of harsh chemicals like powerful detergents which can remove the beneficial flora, Alkaline soaps which change the pH of Skin and leads to the destruction of Skin flora.
- Personal care products can change the pH of Skin. Preservatives in these products can destroy friendly organisms.
- Medications, especially antibiotics which destroy friendly organisms.
- Ageing reduces Sebum secretion which results in less protective organisms.
- Hormonal changes in pregnant woman.
- Help prevent itching, redness and inflammation
- Help maintain and restore the Skin barrier
- Help prevent mal odour
