Parabens are a group of synthetic compounds commonly used as preservatives in cosmetics, personal care products, and some food items. They help prevent the growth of harmful bacteria and mold, extending the shelf life of products. Common types of parabens include methylparaben, ethylparaben, propylparaben, and butylparaben. Despite their effectiveness, there has been concern about the potential health effects of parabens. Some studies suggest that parabens can mimic estrogen in the body, leading to worries about their role in hormone-related issues. As a result, many consumers are seeking paraben-free alternatives in their products.
