Analysis updated September 2026 · How Scout scores
At a glance
Summary
This eyebrow pencil contains a mix of ingredients, including hydrogenated castor oil, which is beneficial for skin hydration. However, the presence of methylparaben, a preservative with potential endocrine-disrupting effects, and PEG-6 beeswax, a synthetic compound, contribute to a moderate processing level. The product's formulation is not entirely natural, which affects its overall safety score.
