This is a spectacularly useful post about the function and safety of parabens in cosmetics, in which the author collects information from a variety of sources and evaluates the reliability of those sources. For example, she provides a nice critique of the Environmental Working Group (EWG), which is the source of many of the OMG TOXIC POISON CANCER scares that come up in relation to makeup and skin care ingredients.
Here is a summary of the post's conclusions, but I highly recommend reading the entire thing. It's fascinating and informative.
So to sum up - my conclusion is based on several key points I've touched on over the 4 headings:I just really love smart, critical writing about cosmetics.
1. The bulk of scientific data shows that parabens are safe, and they are determined to be safe for us in almost all jurisdictions. 2. The scientific literature that fuelled the anti-paraben movement can't prove causation, and in any case the authors themselves say that they can't draw a link and further study is needed. 3. Your body breaks down parabens applied topically through urine and bile. 4. Parabens are used in tiny concentrations at less than 1% in cosmetics and skincare 5. Paraben alternatives are not necessarily safer, or more effective. 6. Parabens are broken down naturally in our environment.
