Parabens
Parabens are common ingredients used to preserve cosmetic and personal care products, helping them stay fresh and safe to use for longer periods. They prevent the growth of harmful bacteria and mold in products like lotions, shampoos, and makeup. While some companies now advertise "paraben-free" products due to consumer preferences, parabens remain widely used in the industry. For recruiters, understanding parabens is important because candidates in cosmetic formulation often work with these preservatives or their alternatives, and this experience is frequently mentioned in resumes and job descriptions.
