At a glance
Summary
This mascara contains beneficial natural ingredients like beeswax and carnauba wax, which are well-tolerated and enhance the product's texture. However, the presence of sodium laureth sulfate, which poses a risk of irritation and potential contamination, along with alcohol denat., which can be drying, affects the overall safety profile. The inclusion of synthetic polymers and preservatives further contributes to a moderate processing level.
