Assessing the Safety of Parabens: Percutaneous Penetration and Risk Analysis
In cosmetics, parabens are widely used due to their low cost and efficacy. In recent years, however, some reports have claimed that these materials exhibit estrogenic activity, which has led to attempts to replace them in formulations. This article reviews penetration studies of parabens spanning the past 20 years to determine whether they pose a risk to human health.
