FAQs About Methylparaben
Are parabens in skincare safe?
According to the EU Cosmetics Regulation, FDA, and independent safety reviews, parabens at the concentrations used in cosmetics are considered safe. The evidence that they pose a health risk at cosmetic use levels is not considered conclusive by major regulatory bodies.
Why do some brands avoid parabens if they're safe?
Consumer demand for "paraben-free" products grew significantly after a 2004 study found parabens in tissue samples. While the study was widely criticized for methodology issues, the consumer preference shift was real and brands responded to market demand.
