What's the difference between a tubing mascara and a regular one?

Tubing mascaras form little polymer tubes around each lash that slide off with warm water, while traditional mascaras use waxes and pigments that need oil or makeup remover. Reviewers across r/drugstoreMUA and mainstream press describe tubing formulas as more smudge-resistant during the day but sometimes less buildable for volume. Heroine Make and the Maybelline Sky High family come up most often when shoppers ask about tubing-style wear.
