Are Parabens Harmful?

 Yes and No.The simple answer is that there are no studies that prove that parabens, as a topically applied ingredient and in the doses that they normally occur in cosmetics, have toxic or carcinogenic effects. For more on the paraben cancer scare, see Mythfoliation: Do Parabens Cause Cancer?.

Parabens, aluminum, lead in lipsticks, talc: there are many panic-inducing headlines about ingredients commonly found in cosmetics. While some are completely spurious, others are well-studied and others are somewhere in between—possibly based on scientifically-valid studies but with circumstances that may not directly applicable to cosmetics (such as for ingredients ingested by lab animals in high concentrations over a long period of time) or with key findings left out of reports that make it to public circulation (such as in the case of an ingredient being proven as cancerous in mice, but the findings being inconclusive in humans).

It may also help you to know that many ingredients used in cosmetics are present in minuscule concentrations that a) have molecules that are large enough to make them unlikely to penetrate the skin, b) even if they could, the concentration is so low and diluted that any impact on the blood or internal organs is still considered unlikely.

Evidence on parabens is still very inconclusive in terms of its link (if it has any at all) to cancer. VMV HYPOALLERGENICS® stopped using parabens because of their allergenicity, not because of their supposed toxicity or cancerous link, both of which have yet to be proven. We use only ingredients that are clinically proven, via published studies, in legitimate medical and pharmaceutical sources, to be safe for their intended use.

While the link between parabens and cancer is weak, the link between parabens and contact dermatitis is very strong. A 2001 review of the published literature on paraben safety[1] states, “Propyl paraben is not carcinogenic, mutagenic or clastogenic … (but) parabens have been implicated in numerous cases of contact sensitivity associated with cutaneous exposure.” This is corroborated by extensive published medical articles[2] and by their consistent inclusion in top allergen lists.[3]

Clearly it works in our favor to have hordes of “parabenighted” folk flock to our paraben-free products. But it would not be right to promote something as serious as a (still unproven) cancer scare. So, by all means, try our paraben-free topical products. But do so to reduce the risk of irritations—not for fear for anything more sinister.
