Summary
This eyeliner contains a mix of synthetic and natural ingredients, with iron oxides providing color and synthetic waxes for texture. While it avoids harsh chemicals like parabens and phthalates, it includes synthetic components like dimethicone and synthetic fluorphlogopite, which are generally considered safe but are not natural. The product's formulation is relatively clean, with no major harmful additives, but the presence of synthetic ingredients prevents it from achieving a top-tier rating.
