Which common preservative is often found in cosmetic products?

Parabens are commonly used preservatives in cosmetic products because they effectively prevent the growth of harmful bacteria, mold, and yeast, thereby extending the shelf life of these products. By inhibiting microbial growth, parabens help maintain the integrity and safety of cosmetics, ensuring that they remain effective for consumers. These compounds mimic natural hormones in the body, which has led to some controversy; however, regulatory agencies have deemed them safe for use in cosmetic formulations at certain concentrations. Their widespread use in creams, lotions, shampoos, and other personal care items illustrates their effectiveness and importance in the cosmetic industry.
