Is Clean Lash waterproof?

No. It is a washable everyday mascara, not a waterproof formula. It is not the pick for swimming or for heavy crying.

Does it smudge under the eyes?

The no-smudge claim is the product's main selling point, and most owners report it holds through a normal day. Very oily lids or heavy rubbing can still cause transfer.

How many coats do I need?

One coat gives a tinted, defined look. Two coats add noticeable length. More than that tends to clump rather than build volume.

Curl hold is modest. On straight lashes, use a lash curler first and expect some drop by the end of the day.

Is it good for sensitive eyes or contact lens wearers?

Many contact lens wearers use it without trouble, but it is a mascara, not an allergy-tested product. Check the ingredient list if you react to cosmetics.
