The chemical ingredient: Phenoxyethanol
Explanation: "Phenoxyethanol is less well-known than parabens, but it has the same preservative qualities. So often products listed as paraben-free will have just replaced it with phenoxyethanol. It's restricted in the E.U., and potential health concerns include allergies and nervous system effects."
The natural option: Anise berry
Why it works: "Anise berry preserves the organic compounds in products and maintains the integrity and the efficacy of formulas. It's best used in oil-based products rather than emulsions."
