The quick answer: no
For the long answer: I quote the American Cancer Society and the summary is no too.
“Parabens are chemicals used as preservatives and as food additives. They can be found in many types of make-up (like lipstick, mascara, concealer, and foundation) and skin care products (like lotion, shaving products, and sunscreen). Parabens can be absorbed through the skin.
Intake of parabens is a possible concern because studies have shown that parabens have weak estrogen-like properties. Estrogen is a female hormone known to cause breast cells (both normal and cancerous) to grow and divide…
In 2004, a small study found traces of parabens in some samples of breast cancer tumors…there are some points about the study findings:
They looked only for the presence of parabens in breast cancer samples, it did not show that parabens caused or contributed to breast cancer development in these cases – it only showed that they were there. What this meant is not yet clear.
…parabens have weak estrogen-like properties, the estrogens that are made in the body are many times stronger…natural estrogens (or hormone replacement) are much more likely to play a role in breast cancer development.
This study did not contain any information to help find the source of the parabens found in the breast tissue – it’s not clear if they might have come from antiperspirants or from some other source.
Most people are exposed to parabens…studies have found some form of parabens in the urine in up to 99% of people in the US…so far, studies have not shown any direct link between parabens and any health problems, including breast cancer…many other compounds in the environment that mimic naturally produced estrogen”
A few Myths & Facts about Parabens
Myth: Parabens cause cancer.
Fact: Parabens have been extensively studied to address this claim and have been deemed safe.
Myth: Parabens are harmful to skin & hair.
Fact: Some people are allergic to parabens & fragances in cosmetics therefore those who are sensitive will have a negative reaction and should avoid them. It is important to visit your doctor if you have any skin concerns, a physician is the most qualified person to help you with your skin concerns.
Myth: Parabens are bad for the environment or “nasty” beauty.
Fact: In a study published in 2015 parabens were found in Marine life, but there seemed to be no negative effects on the study subjects. The significance of this finding is yet to be determined, and probably more studies will be conducted in the future. As of today no environmental damage can be attributed to parabens, partly because what is known about this compound is that it degrades quite fast so it does not seem to accumulate.
What is the use of parabens, anyways?
Parabens are preservatives and preservatives are important to keep our personal care products free of contamination by bacterias or other harmful agents and extend their shelf life, they are not active ingredients but more of an agent necessary to maintain the integrity of a product from it’s manufacturing process until the moment it reaches the consumer and while it is being used by said consumer, basically all of us.
Preservatives are not a bad thing, fear mongering is.
