No worry boos, Cambio's got you.
Turns out, parabens aren't just some evil chemical cosmetic brands are putting in our products just to poison us. When our fave creams, shampoos or some makeups are made, manufacturers will include parabens to prevent bacteria or fungi from growing in our products. Gross. Basically, parabens help our products last longer, and keep us from developing a nasty illness from using that mascara a bit too long.
That being said, parabens may be more dangerous than we thought before. Previous research has found that parabens can often mimic the effects of estrogen, the female sex hormone. When this happens, your body is tricked into thinking it's made more estrogen than it actually has, which leads to reproductive problems and possibly even cancer.
Most parabens in our lotions, hair care products and cosmetics are in very low doses, but researchers at UC Berkley are becoming weary of even that amount. In their study, they found that exposing breast cancer cells to parabens in low doses allowed the cells to grow pretty quickly.
Reading labels can help as well; most products will detail if they're paraben-free. But if you're still curious about whether the products you use have parabens, the Enviromental Work Group's online database Skin Deep allows you to type in your favorite product and will give you a list of all the chemicals in it.
