Parabens are a chemical preservative used in a multitude of different products, but most commonly associated with hair and skin products and medications.
They are very effective as antifungal and antibacterial agents to give products a longer shelf life, but unfortunately can act as an irritant in some people and can cause contact allergic reactions. Parabens are more commonly shown to irritate the skin after it has already been inflamed by another allergen. This is called the ‘Paraben Paradox’.
They have low toxicity compared to other preservatives and rarely cause allergic reactions from being ingested (in the form of medications).
