Parabens are preservatives. And preservatives are necessary, whatsoever. There is no other way to keep bacteria and fungi from developing in cosmetics (and foods), simply because the vast majority of formulas contain water and other nutrients which allow microorganisms to flourish. For them (the microorganisms) water and nutrients are a natural habitat, an oasis.
So, naturally, a question arises: if natural cosmetics do not contain parabens as they claim, how can they keep micro-organisms from growing? How do they keep us from infections? The answer is simple and it is another (rhetorical) question: Who says parabens are the onlypreservatives?
Let me give you a hint. In the early 20th century, there were no refrigerators or deep frosts to store food. To prevent meat from going bad, people (not only in the Greek but in most cultures) stored it in its own fat. As disgusting as this might sound, it was a really effective method. Similarly, to preserve sugar-based homemade sweets, people used citric acid (lemon juice), while to preserve cheese they used olive oil and/or salt. And the beauty of it is that apart from preservation they also achieved fantastic taste!
Citric acid, salt, potassium, various herb extracts like rosemary extract, grapefruit extract, grape seed extract etc, essential oils… These are nature’s preservatives and they are much more effective than chemicals. They are also beneficial for our body in ways you cannot imagine. Learn more about natural preservatives here.
